Cast Stainless Steel CF3M



Cast Stainless Steel CF3M

 

Type CF3M is a Fe-Cr-Ni-Mo alloy of the same family as type CF8M, but with the carbon content restricted to 0.03 percent maximum. This extra-low carbon limit makes the alloy useful in applications requiring field welding where post-weld heat treatment is inconvenient or impossible. Corrosion resistance of CF3M

and general fields of application for the alloy are essentially the same as those of the CF8M grade, and equal to or better than that of the corresponding wrought grade.

Chemical Composition

 

ASTM A743  A351 A744, AISI 316L, DIN 1.4404 X2CrNiMo17-12-2  

Equivalent Grades

1425

Melting Point(oC)

For maximum corrosion resistance, castings of CF3M should be heated in the range 1050 to 1121°C, and then quenched in water to ensure complete solution of carbides and sigma phase.
