ASTM: American society for testing and material

Standard ASTM A500 featured for welding pipe.

ASTM A500 featured class B, specific parameters are as follows:

Tensile strength of 400 mpa yield strength 310 mpa chemical composition: C 0.26 Mn - P 0.04 S 0.05 you can refer to GB 3094 cold drawn square tube standard.

ASTM standard A500 featured involves many grades of material inside. Such as Grade A, Grade B... And so on. Each grade of material has different requirements in performance, can't be replaced general said can take what standard.

Usually material replacement, the replacement material and replaced with the same composition, the mechanical properties of the same.
