BS EN 10088-3 chemical composition tables 2024-4-15

BS EN 10088-3 is the material standard for stainless steel semi-finished products, bars, rods and sections for general purposes. Ferritic, martensitic, precipitation hardening, austenitic and austenitic-ferritic, (duplex), grades are included. The chemical composition of all the grades of stainless steel covered in the standard are listed.

The data given is not intended to replace that shown in individual standards to which reference should always be made.
