1.2842 DIN O2 Oil Hardening Tool Steel - ISO NQA

Jul 05, 2015 · ANNEALING:O2 tool steel is supplied in the annealed and machineable condition. Re-annealing will only be necessary if the steel has been forged or hardened. To anneal, heat uniformly to 720°C, equalise, then furnace cool (hardness about 229 Brinell). Fully machined tools in grade O2 tool steel should be packed during annealing. AISI O2 Tool Steel - O2 Alloy Steel - Special steel china O2 alloy steel Cold-work tool steels belong to the family of high carbon steels that are further classified into oil-hardening steels, high-carbon, high-chromium steels, and air-hardening steels. Oil-hardening cold-work steels are also known as group O steels consisting of O1, O2, O6, and O7 types.

China Cold Work Tool Steel Round Bar 1.2842/O2

All we do is always involved with our tenet " Consumer initial, Trust first, devoting within the food stuff packaging and environmental defense for Cold Work Tool Steel Round Bar 1.2842/O2, Cold Work Tool Steel, Hss M2 Circular Saw Blades, Hss Drill Blanks, We hope we can have a friendly relationship with businessman from all over the world.We stay with the basic principle of "quality MIG Oil Hardening Cold Work Tool Steels O1,O2,O6First use E312 followed by E11018-G followed by the tool steel. Try to provide a minimum of 3 layers of tool steel weld to a minimum depth of 3mm. If the repairs are on annealed steels remember the electrode selected must respond to heat treatment after weld. The weld hardness will depend on the preheat/interpass temperatures plus weld procedures. O1 Tool Steel - Oil-Hardening Cold-Work Steel (UNS T31501)

  • IntroductionOther DesignationsMachinabilityHardeningWeldingHeat TreatmentForgingAnnealingTemperingMartemperingCold-work tool steels are high carbon steels that are further classified into three subgroups such as oil-hardening steels, high-carbon, high-chromium steels, and air-hardening steels. Oil-hardening cold-work steels are also known as group O steels consisting of O1, O2, O6, and O7 types. Type O1 oil-hardening cold-work steel consists of chromium, manganese, and tungsten and is relatively inexpensive. The following datasheet provides details about O1 type.tool steel o2, tool steel o2 Suppliers and Manufacturers A wide variety of tool steel o2 options are available to you, such as aisi, astm, and jis. You can also choose from bending, cutting tool steel o2, as well as from tool steel bar, structural steel bar, and die steel bar tool steel o2, and whether tool steel o2 is is alloy, or non-alloy.
