A351 CF8M vs SA351 CF8M

iainuts (Mechanical) 8 May 06 19:21. Material per ASTM specifications are preceeded by the A, hence the A351. ASME code materials for pressure vessels take this ASTM spec, and then add test requirements to them. The ASME Code material for vessels then gets an S before the ASTM spec, hence the SA351 designation.

CF8M VS CF8 Stainless Steel Casting | JC Casting

As the chemical composition of CF8 includes approximately 18% chromium and 8% nickel by weight, it is also known as 18/8 stainless steel. For its good cavitation resistance, CF8 is the primary choice to cast stainless steel components. Such as pump impellers, some important parts for water handling application.

CF8M

The most significant difference is that A351 has tensile property, inspection, and quality requirements not found in A743. A351 references A703 which in turn sets out the testing & analysis methods and requirements. A743 references A781, a general specification for casting used in non-pressurized applications.
