冷間圧延ステンレス鋼については、従来のBS1449規格が2つのCN規格に取って代わられた：
- EN10088-2: Replaces BS1449-Part 2:1983
- EN10059: Covers heat resisting grades
- EN10259 & Now ISO 9445: Tolerances for cold rolled materials

*NOTE:
Special finishes indicate hot rolled (1) and cold rolled (2) sheets, e.g.: Ground polished hot rolled sheets + 1G/Ground polished cold rolled sheets = 2G.
For further information on stainless steel finishes, please refer to the Zhong Wang technical datasheet on this subject.
Material Certification
Where multi-certification is required, a combination of EN10088-2, EN10029 or 10051 will appear together with the appropriate ASTM Standards.
