Ovako 21CrMoV5-7 Imanite (6132) Steel, +QT
Categories:	Metal; Ferrous Metal; Alloy Steel
Material Notes:	General Information: 21CrMoV5-7 is a steel for fasteners with specified elevated and/or low temperature properties. Imanite has been designed for nitriding, giving similar hardness distribution as case hardening. When using nitriding the distortion due to quenching after carburising can be avoided. Imanite is a M-steel version of 21CrMoV5-7 . M-treatment is very beneficial when the machining is done in Q&T condition and the hardness is about 300 HBW. Information provided by Ovako
