Delivery Condition
EAF+LF+VD, Hot rolled or Forged, Annealed, Hardness≤250HB, Black surface or Machined surface, UT 100% SEP1921 Class 3 D/d passed
 
Characteristics
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.
 
Applications
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.
 
Forging Technique

Heat Temperature	Start Forging Temperature	Finish Forging Temperature	Cooling Method
1120-1140 °C	1080-1100 °C	>=850 °C	Slow Cooling

 
Heat Treatment
Annealing
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.
 
Stress relieving
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.
 
Hardening
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
 
Tempering
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.
For certain cases we recommend to reduce tempering temperature and increase holding time.
