USA UNS	G51601
Corresponding Standard	ASTM A29/A29M-2023 General Requirements for Steel Bars, Carbon and Alloy, Hot-Wrought
Classification	Alloy Steel

51B60 Chemical Element Composition Content (%)

Component	C	Si ^①	Mn	P	S	Cr	Ni ^②	Cu ^②	Mo ^②	B ^③
Minimum Value	0.56	0.15	0.75	-	-	0.7	-	-	-	0.0005
Maximum Value	0.64	0.35	1	0.035	0.04	0.9	0.25	0.35	0.06	0.003

① Silicon may be specified by the purchaser as 0.10 % maximum. The need for 0.10 % maximum generally relates to severe cold-formed parts.
② Residual elements.
③ These steels can be expected to contain 0.0005 % to 0.003 % boron. If the usual titanium additive is not permitted, the steels can be expected to contain up to 0.005 % boron.
