The design and manufacture of a metal component involves a multitude of decision points and will be influenced by considerations such as structural performance, weight, lead time, cost and aesthetics. It is understandable, therefore, that thoughts about how precisely that component is going to be manufactured are often left until the design is at a fairly … Read more
STAINLESS STEEL SA-351 GRADE CF3M
CF3M is a molybdenum bearing modification of CF3 Austenitic Steel alloy and is the cast equivalent of wrought AISI 316L stainless steel. It is the low-carbon modification of CF8M. The presence of molybdenum increases the general corrosion resistance and the resistance to pitting by chlorides.
CF3M has similar corrosion resistance and mechanical properties to CF8M. The difference is that the tensile yield strength of CF3M is somewhat less than that of CF8M at ambient temperatures. CF3M alloy is limited to a maximum temperature of 800F. Applications for the low carbon version (CF3M) would include valve bodies, pump casings, flanges, fittings and other pressure-containing parts where excellent corrosion resistance is required and should be used for parts that will be welded and cannot be solution annealed after welding.
