FORGED VALVES MATERIALS

Forged valves are those valves whose bodies are manufactured out of forged steel. The most common forged materials for valves are:

ASTM MATERIAL	MATERIAL GROUP	RECOMMENDED SERVICE	CASTING MATCHING GRADE
A105(1)	Carbon Steel	General service such as oil, oil vapor, gas, steam and water at temperatures -20°F to 1000°F (-28°C to 537°C).	A216-WCB
A350-LF2 CL1	Low Temperature Carbon Steel	Suitable for temperatures -50°F and not above 650°F (-46°C and not above 343°C).	A352-LCB
A182-F11 CL2	1 1/4% Cr, 1/2% Mo Alloy Steel	High temperatures from -20°F to 1100°F to minimize graphitization (-28°C to 593§C).	A217-WC6
A182-F22 CL3 (2)	2 1/4% Cr, 1% Mo Alloy Steel	For services requiring greater strength than F11 at temperatures from -20°F to 1100°F (-28°C to 593°C).	A217-WC9
A182-F5	5% Cr, 1/2% Mo Alloy Steel	For corrosive/erosive refinery use requiring resistance at temperatures from -20°F to 1100§F (-28°C to 590°C).	A217-C5
A182-F9	9% Cr, 1% Mo Alloy Steel	For services involving media with higher Sulphur content to combat oxidation to 1100oF (593°C).	A217-C12
A182-F304	18% Cr, 8% Ni Stainless Steel	For corrosive services and atmospheres from -450°F to 1000°F (-268°C to 537°C).	A351-CF8
A182-F316	18% Cr, 8% Ni, 2% Mo Stainless Steel	For superior resistance to corrosion from -450°F to 1000°F (-268°C to 537°C).	A351-CF8M

1. Allowed but not recommended for long term use above 800oF (425oC)
2. Warning to the possibility of excessive oxidation (scaling) when used above 1050oF (563oC)

ASTM A105 VALVE

ASTM A105 are widely used carbon steel (forged) valves:
