Medium carbon steel may become slightly tougher although it cannot be harden to the point where it cannot be filed or cut with a hacksaw (the classic test of whether steel has been hardened). Grade Summary: O1 Tool Steel is a general purpose oil-hardening tool and die steel. Strip The hardenability of shallow-hardening steels, those steels that will not through-harden bar sizes larger than 1.0 inch (25.4 mm), except for carbon tool steels, has traditionally been determined by the SAC hardenability test. The temperature should never exceed 300º at any time. The exceptions to this are the prehardened steels such as P-20, Brake Die, Holder Block and Maxel Tooling Plate which are furnished at 28/32 HRC and used at that hardness. O1, which is often referred to as 01, belongs to the O steel grade family which contains steel grades such as O1, O2, O6 and O7. The hardening temperature is chosen to suit the steel in question, always keeping in mind the use to which the tool is to be put. 550 HV level, is about 4 mm. Carbon steels and vanadium-alloyed steels The hardening of these steels, which are made with carbon contents between 0,80% and 1,20%, is quite straightforward: Since the rate of carbide dissolution proceeds rapidly, the holding time, as a consequence, is short and therefore the heating of small tools can often take place without any extra precautions against atmospheric oxidation.
