ARMCO GAINEX Steels comprise a family of five low-cost structural carbon steels. This family includes: GAINEX-35, GAINEX-40, GAINEX-45, GAINEX-50 and GAINEX SA (Strain ageable); the numbers following GAINEX refer to minimum specified (ordered) yield strengths in 1000 psi. These steels are well suited to the automotive, farm and construction equipment, and appliance industries for such applications as truck bodies, light poles, bumper support members and parts for agricultural implements. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness and fatigue. It also includes information on corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: CS-69.
