Regular Austenitic Supply

201 / 304 / 304L

201304304L

Common plate and sheet grades for fabrication, equipment, enclosures, general components and projects where these grades are already specified.

316-Series Supply

316 / 316L

316316L

Supplied when the drawing, project specification or service requirement calls for the 316-series material route.

Heat-Resistant / Project Grades

309 / 309S / 321

309309S321

These grades are normally purchased because temperature, fabrication or service requirements have already been defined. We confirm the full grade and delivery condition before quotation.

Duplex / Other Regular Supply

2205 / 410 / 904

2205410904

2205 follows a duplex stainless route, while 410 and 904 belong to other distinct stainless material routes. These grades are quoted from the exact grade, size, finish and project requirement rather than treated like ordinary 300-series stock.

Product specifications such as ASTM A240 and general flat-rolled requirements such as ASTM A480 can be reviewed at quotation stage when they apply to the order.

Grade Routing

Keep the Grade Decision Simple

The website should help you send an RFQ, not encourage material substitution. If the grade is already fixed, use it. If the grade is not fixed, tell us the service and fabrication requirement so the material can be reviewed before quotation.

Do not choose stainless grade from appearance alone.

Two sheets can look similar while having different chemistry and service requirements. Grade, finish and surface treatment are separate items and should all appear correctly on the RFQ.

Rolling Route

Plate and Sheet Do Not Use the Same Surface Route

Hot-rolled stainless plate and cold-rolled stainless sheet can share the same grade family, but their thickness route, finish and handling requirements are different.

01

Hot-Rolled Plate

Common for thicker plate, fabricated equipment and cut components, often supplied with a No.1-type hot-rolled finish.

02

Cold-Rolled Sheet

Used when thinner gauge, cleaner surface and finishes such as 2B or BA are part of the requirement.

03

Order by Thickness × Width × Length

Example: 6 × 1500 × 6000 mm for plate, or 1.5 × 1219 × 2438 mm for sheet. Final availability depends on grade, finish and mill route.

Surface Finish & Treatment

Specify the Surface Before We Quote

We can supply standard mill finishes, polished and brushed finishes, mirror and decorative surfaces, plus post-fabrication treatments. The grade and surface should be stated separately because the same stainless grade can be delivered with very different surface requirements.

Mill, Polished & Brushed Finishes

These are the finishes most buyers specify directly on plate and sheet RFQs.

No.1Hot-rolled, annealed and pickled industrial surface, common on thicker stainless plate.
2DCold-rolled matte finish with lower reflectivity than 2B.
2BCommon smooth cold-rolled finish for sheet and general fabrication.
BABright-annealed finish where a cleaner, brighter surface is specified.
No.3Coarser polished finish for orders that require that grinding route.
No.4Common brushed / ground finish with visible directional texture.
No.6 / SatinLower-reflection satin appearance for specified decorative or equipment surfaces.
HL / HairlineLong directional lines for projects that call for a hairline appearance.
SB / Scotch-BriteFine satin-brushed surface with a controlled low-gloss appearance.
No.8 / 8K MirrorHighly polished reflective mirror surface for orders where a mirror appearance is specifically required.

Decorative & Patterned Surfaces

These finishes are quoted from the required appearance, pattern, color and finished sheet size rather than treated as standard 2B stock.

VibrationNon-directional fine texture without one dominant straight brushing direction.
Bead BlastedUniform low-reflection matte appearance produced by controlled blasting.
EtchedPatterned surface produced where an etched design is part of the order.
Embossed / PatternedRaised or pressed surface pattern supplied to the selected design and sheet requirement.
PVD ColoredDecorative colored surfaces such as gold, black or other specified tones where PVD treatment is required.
Stainless steel vibration bead blasted embossed etched and PVD decorative finishes

Post-Fabrication Surface Treatment

These treatments serve a different purpose from No.4, HL or 8K appearance finishes and are specified according to fabrication and service requirements.

PicklingUsed to remove heat tint, scale or suitable surface contamination after fabrication where required.
PassivationUsed on clean stainless surfaces when the order calls for a passivation treatment after processing or fabrication.
ElectropolishingElectrochemical surface finishing for projects that specifically require a smoother, cleaner finished surface.
Stainless steel pickling passivation and electropolishing treatment
Finish and treatment are not the same field.

For example, a buyer can order 304 sheet with a No.4 finish and still have a separate requirement for protective film. A fabricated stainless part can also require pickling or passivation after cutting and welding. Put each requirement on the RFQ separately.

Protective Film

Does the Surface Need Protection During the Next Process?

Protective film is most relevant when a finished sheet surface must survive cutting, bending, forming or site handling. It should be confirmed before processing, not added as an afterthought.

01

One Side or Both Sides

State which surface needs film protection when the order has a visible or controlled face.

02

Keep Film During Cutting?

If the film must remain during laser cutting, bending or fabrication, include that in the RFQ.

03

Finish Matters

2B, BA, No.4, HL, SB and 8K / Mirror orders can have different protection needs depending on the buyer's next operation.

Dimensions & Surface Acceptance

A No.1 Plate and an 8K Mirror Sheet Are Not Inspected the Same Way

The inspection route follows the ordered finish and product form. A heavy No.1 plate is judged differently from 2B, BA, No.4, HL or 8K sheet where surface appearance carries more weight.

Dimensions

Thickness, Width, Length & Flatness

Dimensions are checked against the confirmed order using measurement methods appropriate to the product thickness and form.

Surface

Scratches, Marks & Finish Consistency

Surface acceptance follows the ordered finish rather than applying one visual standard to every stainless sheet and plate.

Protection

Film, Edges & Handling Damage

Protective film, sheet edges and handling marks are checked where the delivered surface condition makes them relevant.

Cutting & Clean Handling

Stainless Steel Should Not Be Handled Like Carbon Steel

Cutting quality matters, but so does what touches the stainless surface before and after cutting. Avoidable carbon-steel contamination can create problems even when the stainless grade itself is correct.

01

Laser / Plasma / Shear Routes

The cutting method is selected from thickness, part geometry, edge requirement and surface finish.

02

Cut Edges

Processed edges are reviewed for the finished dimension and the condition required by the next fabrication step.

03

Cross-Contamination Control

Stainless surfaces should be kept away from avoidable carbon-steel grinding dust, rusty contact surfaces and unsuitable handling tools.

04

Clean Separation

Finished sheets and cut parts can use clean separators or protected supports where surface preservation matters.

Grade Verification

When the Grade Matters, Verify the Material

PMI can support grade identification on stainless orders where material mix-up is a concern. It is useful for confirming alloy identity, but it is not a replacement for the complete material certificate.

01

304 vs 316 Family

PMI can support alloy-family identification where mixed stainless grades are handled in the same project.

02

Duplex 2205

Grade verification becomes especially important when the order contains a duplex stainless route rather than an ordinary 300-series stainless order.

03

PMI Has Limits

PMI does not prove every mechanical property, heat treatment condition or requirement shown on the MTC.

MTC & Traceability

Cut Pieces Still Need to Match the Original Stainless Material

When a full sheet or plate is cut into smaller parts, the identification required by the order should remain linked to the original heat, plate or coil records.

01Mill / heat identity
02Plate / coil record and MTC
03PMI where required
04Cut-piece identification
05Package / pallet tag
06Shipment documents
PMI and MTC do different jobs.

PMI supports material identity checks on the physical product. The MTC carries the broader mill test information for the ordered heat or batch.

Packing & Shipment

Protect the Surface That the Buyer Ordered

Heavy No.1 plate, 2B / BA sheet, No.4 / HL / 8K decorative sheet and finished cut parts do not need the same export packing. Packing follows the surface, weight, edges and handling risk.

01

Heavy No.1 Plate

Stable dunnage, multiple support points, steel bands and practical lifting access are the main concerns.

02

2B / BA / No.4 / HL / 8K

Protective film, clean separators, edge protection and suitable wrapping are increased when the finished surface must arrive without avoidable scratches or rough contact marks.

03

Cut Parts

Pallets, boxes, clean separators and individual identification can be used when smaller finished pieces need controlled handling.

Ordering Questions

Common Questions Before Quotation

What is the practical difference between 304 and 316L plate?

They are different stainless grades and should follow the project requirement. Buyers often consider 316/316L when the service environment calls for a different corrosion-resistance route than 304/304L. Do not substitute one for the other without material review.

Should I specify No.1 or 2B?

No.1 is commonly associated with hot-rolled stainless plate. 2B is a common cold-rolled sheet finish. Use the finish stated on the drawing or tell us how the surface will be used after delivery.

Can stainless sheet be supplied with protective film?

Yes, where the finish and processing route support it. State whether one or both sides need protection and whether the film must remain during cutting or forming.

Can you supply 2205 stainless steel plate?

Yes. 2205 is included as a regular duplex stainless route. Send the full grade, thickness, width, length, finish and any PMI or project-document requirement so we can quote it correctly.

Can you supply 8K mirror, PVD, embossed and other decorative finishes?

Yes. We can supply No.8 / 8K mirror, vibration, bead blasted, etched, embossed / patterned and PVD colored surfaces. Send the grade, thickness, sheet size, finish and whether protective film is required.

Do pickling, passivation and electropolishing mean the same thing?

No. They are different post-fabrication surface-treatment routes. State the required treatment separately from the visual finish such as 2B, No.4, HL or 8K.

Does PMI replace the MTC?

No. PMI supports physical material identification. The MTC provides broader mill test information for the heat or batch, so the two serve different purposes.
