CF8M is a pressure-bearing component, austenitic stainless steel casting. Executive standard: ASTM A351-2018. CF8M is one type of 316 stainless steel

The chemical composition of CF8M is as follows:

Content	C	Si	Mn	P	S	Ni	Cr	Mo
Min.	–	–	–	–	–	9.0	18.0	2.0
Max.	0.08	1.5	1.5	0.040	0.040	12.0	21.0	3.0

CF8M vs SS316 Standard

CF8M is defined in ASMT A351, ASMT A743, and ASTM A744, which is for casting purposes only.

If they used AISI 316. The difference is clear too.

AISI 316 belongs to American Standard austenitic stainless steel. Executive standard: ASTM A 959-2004. The chemical composition of AISI 316 is as follows:

Content	C	Si	Mn	P	S	Ni	Cr	Mo
Min.	–	–	–	–	–	10.0	16.0	2.0
Max.	0.08	1.0	2.0	0.045	0.03	14.0	18.0	3.0
