AISI O2 / DIN EN 90MnCrV8 1.2842 Oil Hardening Tool Steel Bar / Rod
INTRODUCTION
AISI O2 tool steel is an oil hardening tool steel which is supplied in the annealed condition and characterized by its characteristics of offering good durability. Tool steel O2 is with excellent wears resistance and its ability to hold a good cutting edge. 02 steel is good quality general purpose tool steel often used where the expense of a high carbon high chromium tool steel would not be justified.
AISI O2 steel has working hardness up to 63-65HRC. Steel O2 makes pretty decent performer for light/medium use knives at that hardness.
APPLICATIONS
Steel O2 is used as tool steel for universal use, highly stressed plastic moulds, mould inserts for high hardness and abrasive stress, blanking and stamping tools for all types cutting sheet metals up to 6 mm thickness, cold forming dies, cutting and punching tools of all types, shear blades for paper, plastic and metalworking industries, reamers, thread chasers and cutting tools, pressure pads, guide pins, taps, measuring tools, precision calipers and plug gauges, woodworking tools, plastic and rubber compression moulds, deep drawing tools, clipping.
