ASTM A131 AH40 high Strength Chemical Composition:

A131 AH40 high Strength Chemical Composition
Grade	The Element Max (%)
Grade	C	Si	Mn	P	S	Al	N
A131 AH40	0.18	0.1-0.50	0.90-1.6	0.035	0.035	>0.015
	Nb	V	Ti	Cu	Cr	Ni	Mo
	0.02-0.05	0.05-0.10	0.02	0.35	0.2	0.4	0.08

Crack Sensitivity: Pcm = (C+Si/30+Mn/20+Cu/20+Ni/60+Cr/20+Mo/15+V/10+5B)%
Carbon Equivalent: Ceq = 【C+Mn/6+(Cr+Mo+V)/5+(Ni+Cu)/15】%
