The applicable edition of each standard should be confirmed in the purchase order.

Raw material compliance does not automatically certify a fabricated assembly, welded pressure component or finished product for a specific engineering application.

Where applicable, finished components must also comply with customer drawings, approved welding procedures, dimensional requirements and relevant industry regulations.

6. Custom Dimensions, Tolerances & Surface Requirements

Unlike standard stainless steel products, custom-manufactured components do not have a single universal dimensional range or tolerance.

Production capability depends on material thickness, machine capacity, geometry, finishing operations and component complexity.

Custom dimensions are manufactured according to approved drawings.

Important parameters include:

Overall length, width and height

Material thickness

Hole diameter and location

Edge distance

Bend angle and bend radius

Tube OD and wall thickness

Machined diameters and threads

Assembly dimensions

Manufacturing Tolerances

Tolerance requirements should distinguish between:

General Dimensions: Non-critical dimensions governed by the agreed drawing requirements.

Precision Features: Functional holes, mating surfaces, threads and other features requiring tighter control.

Fabricated Assemblies: Overall dimensions affected by multiple cutting, bending and welding operations.

Surface Requirements: Roughness, finish direction, appearance and acceptable surface defects.

Critical tolerances must be reviewed before quotation.

General tolerance standards may be adopted where appropriate, but they should be explicitly agreed rather than assumed.

Drawing Requirements

For efficient technical review, provide:

2D Drawings: PDF, DWG or DXF
