Product Description GB 9Mn2V | DIN 1.2842 | BS B02 | ASTM O2 Cold Work Tool Steel Quick Details1: AISI O2 steel introduction AISI O2 tool steel is an oil hardening tool steel which is supplied in the annealed condition and characterised by its characteristics of offering good durability. Tool steel O2 is with excellent wear resistance and its ability to hold a good cutting edge. 02 steel is a good quality general purpose tool steel often used where the expense of a high carbon high chromium tool steel would not be justified. 2: AISI O2 Steel equivalentCountryChinaJapanGermanyUSAUKStandardGB/T 1299JIS G4404DIN EN ISO4957ASTM A681BS 4659Grade9Mn2V 1.2842 / 90MnCrV8O2B023: AISI O2 steel chemical compositionGradeCMnPSSiCrVMoO2 / T315020.850.951.401.800.030.03. . .0.50. . .0.50. . .0.300.301.2842 / 90MnCrV80.850.951.802.200.030.030.100.400.200.500.050.20. . .B020.850.951.501.800.0350.035. . .0.40. . .. . .. . .0.25. . .9Mn2V0.850.951.702.000.030.03. . .0.40. . .. . .0.100.25. . .4: AISI O2 steel mechanical properties The mechanical properties mainly include tensile strength, yield strength, elongation, area or reduction, hardness, impact value, non-metalic inclusion etc. Different heat treatment, the mechanical properties will be different, such as normalized, tempered, QT.
