Type CF-3M is an iron-chromium-nickel-molybdenum alloy with carbon limited to 0.03% maximum. This extra low carbon limit makes the alloy useful in applications requiring field welding where post-weld heat treatment is inconvenient or impossible. As normally produced, this alloy has an austenitic microstructure containing discrete pools or stringers of ferrite amounting to about 20% by volume. Type CF-3M has high resistance to corrosion and is recommended for the chemical and allied industries. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness. It also includes information on corrosion resistance as well as casting, heat treating, machining, and joining. Filing Code: SS-335. Producer or source: Stainless steel foundries.
