Ovako 39MnCrB6-2 BCM414 Steel, +QT
Categories:	Metal; Ferrous Metal; Alloy Steel
Material Notes:	General Information: EN 10083-3 is one of the standards met by this steel grade. This grade is classified as a WR-steel, which stands for wear-resistant steel. This group of steel includes a broad range of grades with a wide range of hardness levels 350 – 650 HV, dimensions and steel grades designed to give you a wear-resistant advantage when making product exposed to a high degree of wear and where service life is important. WR-steels are characterised by consistent properties and cost effectiveness due to optimized alloy content for different end applications.
