Plate selection path

Start with the duty, not a grade number.

A useful enquiry separates the application requirement from the material choice. Record what the plate must withstand, then confirm the designation and acceptance criteria under the selected standard.

01 / Service conditions

Describe where the plate will work.

State the medium, temperature range, exposure, cleaning regime, fabrication route, and any project-specific design constraints.

Material suitability and engineering approval remain project decisions.

02 / Standard

Name the governing document.

Record the ASTM, EN, JIS, or project specification reference and revision required by the buyer.

03 / Grade

Use the matching designation.

Keep the grade name tied to the selected standard; do not assume that similarly named designations are interchangeable.

04 / Geometry

State dimensions and tolerances.

Include nominal thickness, width, length, quantity, and the dimensional or flatness criteria that matter to the job.

05 / Finish

Define the required surface.

Separate mill condition, visual finish, surface-direction requirements, and any protective handling instructions.

06 / Processing & QA

Attach the acceptance detail.

Describe cut profiles, edges, holes, forming needs, inspection points, test requirements, and requested documents.

Stainless steel plate stock with protected, identifiable handling.

Plate thickness and surface inspection context.

Plate machining route and delivered-condition context.

Quote-ready worksheet

Make every requirement visible.

A complete specification reduces hidden assumptions. If a field is not yet known, mark it for supplier review rather than inventing a value.

Review the buyer’s guide

Field What to state Why it matters

Standard & grade Document reference, revision, grade designation, required condition Sets the governing material and acceptance language

Dimensions Thickness, width, length, quantity, dimensional tolerances Defines the required product geometry

Surface Finish, visual direction, handling or protection instructions Aligns appearance and downstream fabrication needs

Processing Cut shape, edge or bevel detail, holes, forming notes, drawing reference Clarifies the requested supply scope

Inspection Test, inspection, marking, traceability, and document requirements Makes buyer acceptance criteria reviewable

Delivery context Destination, packaging constraints, requested date, contact details Allows a supplier to assess the commercial request

Finish & processing

Separate material choice from supply scope.

Grade alone does not define a finished plate requirement. Use the surface and process resources to state what condition is required and what work, if any, should be included in the request.

Surface planning

Define finish and appearance.

Review finish terminology, then record the exact condition required by the drawing or project specification.

Open surface finish guide Processing planning

Describe downstream work.

Identify cutting, edge, forming, welding, or inspection instructions that should be reviewed with the material request.

Plate resources

Move from research to a reviewable request.

Use the guide for selection context, the calculator for an estimate, and the RFQ page to send the known specification fields for supplier confirmation.
