EN Standards for Stainless Steel C.R. Sheet

For Cold rolled stainless steel the old BS1449 standard has been replaced by two EN Standards:

EN10088-2 Replaces BS1449-Part 2: 1983

EN10059 - Covers Heat Resisting Grades

EN10259 & Now ISO 9445: Tolerances for COLD Rolled material

Material Certification

Where multi-certification is required, a combination of EN10088-2, EN10029 or 10051 will appear together with the appropriate ASTM Standards.
