AS 1204 steel plates

[mariovalenti]

I have not enough information about the chemical composition of AS 1204-10 steel (somebody also talked to me about it as ASME 1204 instead of AS 1204).

I would like to know if this steel is resistent to NH3 (ammonia). For example to know if its chemical composition have copper.

Thank you in advance.

AS 1204 could refer to an Australian Standard - Structural Steels: ordinary weldable grades. These are just C-Mn steels with no intentional Cu additions.

However, I can't match the '-10' part to anything. The grade designation in AS 1204 is based upon yield strengths (e.g. AS 1204 grade 200 = 200 MPa min yield).
