Abstract

SAE 50B50 is a low-chromium alloy steel with boron added to provide a substantial increase in its hardenability. Its higher hardenability is reflected in higher hardness, especially in the liquid quenched-and-tempered condition. It is used a wide range of machinery and tool applications where its medium hardenability and strength meet the requirements. 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, and joining. Filing Code: SA-386. Producer or source: Alloy steel mills and foundries.
