CF8 Stainless Steel Casting. AISI 304 or CF8 stainless steel castings means the casting parts made of CF8 stainless steel. It is a general grade, belonging to austenitic stainless steel. It is widely used in the foundry industry. The standard composition of CF8 stainless steel is 18% chromium plus 8% nickel. It is non-magnetic.
SS316 is defined in ASTM A240 and ASTM A276, it's for plate, sheet, strip or stainless steel bars. Another grade is named as F316, which is from ASTM A182 for Forged parts only. TP316 will be found in ATSTM A376 for pipe only. If you want to buy castings, Pls indicate CF8M as material, otherwise you can adopt SS316.

CF8M and CF3M are two different types of austenitic stainless steel with distinct differences between them. While they share similar mechanical properties such as tensile strength and elongation values, their chemical compositions set them apart from each other—with the major difference being the amount of chromium present within each …
