CG3M ASTM A743 A744 A351 Grade（UNS）：J92999 Alloy Family: Austenitic Stainless Steel Equivalent: 317L stainless steel
CG3M alloy is an austenitic alloy based on molybdenum. Compared with conventional Cr-Ni austenitic stainless steel such as CF3 alloy, it has stronger chemical corrosion resistance.
Compared with conventional stainless steel, this alloy has higher ductility, stress corrosion resistance, compressive strength and high temperature resistance. It is a low carbon grade, which has anti sensitization performance during welding and heat treatment.
The alloy has good sea water resistance and corrosion resistance, which is often used to make marine equipment and chemical products.

317L stainless steel
National standard: ASTM
317L stainless steel is more resistant to the corrosion of sulfuric acid solution than conventional chromium nickel stainless steel. The corrosion resistance of the alloy increases with the increase of molybdenum composition. 317L can withstand up to 5% sulfuric acid at temperatures up to 120 ° f (49 ° C). These alloys exhibit excellent corrosion resistance at temperatures below 100 ° f (38 ° C) and resist higher concentrations of solutions.
317L stainless steel has excellent oxidation resistance, and the scale formation rate is low when the temperature is not higher than 1600-1650 ° f (871-899 ° C) in ordinary atmosphere.
