Hot Forming:
Forging: 1050 to 850ºC, slowing cooling in furnace.
Heat Treatment:
Annealing: 800 to 850ºC, slow cooling in furnace (10-20ºC/hr), down to approx. 600ºC, cooling in air. Hardness after annealing: max. 250HB.
Stress relieving: approx. 650ºC, slow cooling in furnace. Hold in neutral atmosphere for 1 to 2hours.
Hardening: 930 to 960ºC, oil, salt bath(220 to 250ºC or 500 to 550ºC), quenching in forced air, for thickness up to 30mm. Hardness obtainable, 63 to 64 HRC.
Tempering: As required. Slowly heating to tempering temperature right after hardening. Recommended to temper 2 or 3 times to increase toughness.

* Hardening temperature: 950ºC, specimen size: dia25mm
Properties:
Classic high chromium cold work steel. High wear resistance due to its ledeburitic structure, very good deep hardening properties and dimensional stability. Moderate toughness.
Applications:
High performance blanking and punching dies for sheet thickness up to 3 mm; circular and flat shear blades for sheet thickness up to 2 mm; cold drawing tools, broaches; tools for the production of nails, screws, nuts and rivets; cold extrusion tools; cold hobbing tools; flanging rolls; guide rolls; rollers of all shapes for continuous production of steel tubes and profiles; cold forming tools for ceramics and powder metallurgy and similar tools.
