What is this standard about?
This is the first of a five-part European standard on stainless steels. This part details the chemical composition of stainless steels. The other parts cover technical delivery conditions for different types of stainless steels.
Who is this standard for?
- Manufacturers, suppliers and procurers of stainless steel products
- Users of stainless steel products
Why should you use this standard?
BS EN 10088 offers the most up-to-date guidance on specifications and composition of materials relating to stainless steel products. It lists the chemical composition of stainless steels, subdivided in accordance with their main properties into:
- Corrosion resisting steels
- Heat resisting steels
- Creep resisting steels
What’s changed since the last update?
This revision supersedes the 2005 version of the standard which is withdrawn. It has been updated by industry experts to harmonize with other standards and align with latest developments and best practice. It includes the following technical changes:
- Addition of austenitic grades 1.4615 (also part 3), 1.4618 (2), 1.4376 (2), 1.4640 (2), 1.4646 (2, 3), 1.4020 (3), 1.4378 (3)
- Addition of austenitic-ferritic (duplex) grades 1.4162 (2, 3), 1.4662 (2, 3), 1.4658 (3), 1.4482 (2, 3), 1.4062 (2, 3), 1.4669 (3),
- Addition of ferritic grades 1.4621 (2), 1.4600 (2), 1.4607 (2), 1.4611 (2, 3), 1.4613 (2, 3), 1.4630 (2), 1.4634 (2)
- Addition of martensitic grade 1.4150 (3), addition of precipitation hardening grade 1.4612 (3)
- Chemical composition changed for:
- austenitic grade 1.4371, 1.4597
- austenitic ferritic grade 1.4362
