SS400 (SS41) material

hi, I couldn't find the chemical analysis and physical properties of ss400 (ss41). (these materials are JIS standarts I only know this) and I couldn't match this material with EN standarts. If anybody help me, I will be very happy. thanks for your help..

There is no a 400 stainless steel in the AISI nomenclature. There is however the 400 serie of stainless steels, that includes many ferritic and martensitic stainless steels, each one having its own formula and properties.
The AISI 410, for example, is a martensitic stainless steel with a chromium content of 11-13%.

SS400 (e.g., SS41) is used by JIS and KS (Korean Standard) to designate a carbon steel product similar in nature to that of ASTM A-36.

However, there are significant differences in shape material thickness (e.g., Metric sizes are used), shape sizes and profiles (e.g., Roll I and H beams do not have the standard "American" taper) and yield strengths.

Chemical analysis differs slightly.

One learns something new every day. Frankly speaking, I know nothing of Japanese and Korean standards.
