2.Chemical Composition(wt.%)

Grade	C	Si	Mn	P	S	Cr+Ni+Cu+Sb	Nb+V+Ti	Alt	Ceq
A~E	≤0.18	≤0.35	0.60~1.60	≤0.035	≤0.035	≤1.0	≤0.12	0.020~0.060	≤0.36
AH32~EH36	≤0.18	≤0.50	0.90~1.60	≤0.035	≤0.035	≤1.0	≤0.12	0.020~0.060	≤0.36

Note: Nb, V and Ti composite micro-alloying were adopted;
Cr, Ni, Cu and Sb are intentionally added to improve corrosion resistance;
Ceq(%)=C+Mn/6+(Cr+Mo+V)/5+(Cu+Ni)/15.
