SELECT B: Cold Work Die Steel, Type A2

SELECT B is a fully uniform air-hardening die steel having abrasion resistance intermediate between Olympic (AISI Type D2) high-carbon, high-chromium die steel and Badger (AISI Type O1) oil-hardening die steel. SELECT B has excellent non-deforming, deep-hardening characteristics and good toughness. Its machinability is comparable to most oil-hardening tool steels. Among its many uses are cold blanking and forming dies, rolls, punches, gages and broaches. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on forming, heat treating, and machining.
