Tri-Steel is a high strength low-alloy steel which is resistant to shock, atmospheric corrosion, abrasion, and fatigue and has good workability and welding properties. It is intended for applications requiring high strength for which a carbon steel is not adequate. This datasheet provides information on composition, physical properties, elasticity, tensile properties, and compressive and shear strength as well as fatigue. It also includes information on corrosion resistance as well as forming, machining, and joining. Filing Code: SA-189. Producer or source: Inland Steel Company.
