AISI 4032 is a molybdenum alloy steel of moderate hardenability. It is used extensively in the automotive industry. This steel combines moderate strength and hardness with good ductility and toughness in the quenched-and-tempered condition because it is relatively free from temper embrittlement when tempered in the range 850-1100 F. Among its many uses are nuts, bolts, studs, machinery parts and fasteners for the transportation and other industries. AISI 4032H is a similar steel except that it has a slightly wider range of carbon and manganese. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: SA-411. Producer or source: Alloy steel mills and foundries.
