Chemical and Mechanical Requirements for Stainless Steel - ASTM A351 CF8M

Jan 21, 2024

For stainless steel (CRA) valves, ASTM A351 CF8M (Austenitic Stainless Steel) is mostly commonly used for casting of body&bonnet and other base materials of pressure-containing parts.

Notes: All requirements are for standard material, for special requirements like NACE please refer to the relevant standard.

Chemical Requirements

Element % (max, except where a range is given)

Material Grade

NiC

CF8M J92900

0.08

1.50

0.040

18.0~21.0

9.0~12.0

2.0~3.0

Tensile Requirements

Material Grade	Tensile Strength, ksi (MPa)	Yield Strength, ksi (MPa)	Elongation in 2 in.(50mm), %
CF8M J92900	70 (485)	30 (205)	30

The equivalent material in forged type is ASTM A182 F316(refer to the standard accordingly).
