◆ Delivery Condition
EAF+(ESR) or EAF+LF+VD+(ESR), Hot rolled, Annealed, Hardness≤235HB,
Black surface or Machined surface (Peeled, Turned, Grinded), UT 100% Passed
◆ Characteristics
1. It is a kind of Chrome-vanadium steel with the middle hardenability for hardening
in oil and water, relatively good toughness at the high hardness, good resistance to
the wear and cutting power.
2. More difficult ductility during the heat and good workability in the annealed state.
◆ Applications
Tools for cold cutting, i.e. cutting tools and punching tools, shear blades for cutting of materials of smaller thicknesses. Cutting tools for machining by smaller cutting speeds,
e.g. drills, reamers, screw taps etc. Further for molds and auxiliary components, e.g.
ejectors, pins etc.
◆ Heat Treatment
Annealing |
710 to 750°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. 235 HB.
Stress relieving |
Slow cooling in furnace; intended to relieve stresses set up by extensive machining,
or in complex shapes.Approx. 650°C
After through heating, hold in neutral atmosphere for 1-2 hours.
|
780 to 810°C / Water
810 to 840°C / Oil
(up to 15mm diameter).
Holding time at hardening temperature: 15 to 30 minutes.
Obtainable hardness: 64 - 66 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 average hardness figures to be obtained please refer to the tempering chart.
For certain cases we recommend to reduce tempering temperature and increase holding
time.
What we can offer?
