ASTM A204 grade C standard specification for Alloy Steel plate

ASTM A204 grade C is a type of ASTM A204 steel. Cited properties are appropriate for the as-fabricated (no temper or treatment) condition. It has the highest strength and lowest ductility compared to the other variants of ASTM A204 steel.

ASTM A204 grade C chemical composition:

Thickness(mm)	C	Si	Mn	P	S	Mo
T≤25	0.23	0.15-0.40	0.90	0.035	0.035	0.45-0.60
25<T≤50	0.26
50<T≤100	0.28
T>100	0.28
