1. A kind of high alloyed CrMoV steel for cutting tool and cold work tool steel.
2. Quite good hardenability and wearing resistance, and small distortion after quenching.
3. Not good impact toughness, be liable to fracture and form inhomogeneous eutectic carbides.
High-duty cutting tools (dies and punches), blanking and punching tools, wood working tools, shear blades for
cutting light-gauge material, thread rolling tools, tools for drawing, deep drawing and cold extrusion, pressing tools
for the ceramics and pharmaceutical industries, cold rools (working rolls) for multiple-roll stands, measuring
instruments and gauges, small moulds for the plastics industry where excellent wear resistance is required.
800 to 850°C
Slow controlled cooling in furnace at a rate of 10 to 20°C/hr down to approx. 600°C, further cooling in air.
Hardness after annealing: max. 250 HB.
650 to 700°C
Slow cooling in furnace; intended to relieve stresses set up by extensive machining, or in complex shapes.
After through heating, hold in neutral atmosphere for 1-2 hours.
980 to 1010°C
Oil, salt bath (220 to 250°C or 500 to 550°C), air blast, still air.
Tools of intricate shape or with sharp edges should preferably be hardened in air or salt bath.
Holding time after temperature equalization: 15 to 30 minutes.
Obtainable hardness: 63 - 65 HRC
Slow heating to tempering temperature immediately after hardening/time in furnace 1 hour for each 20 mm of workpiece thickness but at least 2 hours/cooling in air.
