AISI 5147 is a low-chromium (nominally 1% chromium), intermediate-hardenability alloy steel for medium-duty applications. It is normally hardened by quenching in oil. It has a wide range of applications for transportation equipment, farm implements, tools and industrial machinery. 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-334. Producer or source: Alloy steel mills and foundries.
