Steel alloy 41L40 cold roll is a free-machining alloy (FMA), ideal for parts that require high wear resistance and toughness. The addition of lead makes it easy to machine, but results in lower impact strength than other steel alloys. 41L40 has good strength and ductility, and resists stress and creep at prolonged high temperatures.
41L40 has a machining cost factor of 2.8 when compared to steel 12L14. It is not ideal to weld due to its lead content. 41L40 can be heat treated, plated, forged, and annealed.
