◆ Delivery Condition

EAF+(ESR) or EAF+LF+VD+(ESR), Hot rolled or Forged, Spheroidizing Annealed, Hardness≤220HB, Black surface or Machined surface, UT 100% Passed

◆ Characteristics

1. Cold work tool steel with high dimensional stability at heat treatment.

2. Very high cracking resistance. High machinability, medium thoughness and wear resistance.

◆ Applications

Tools (punches) and dies for blanking, punching and similar operations; threading and

wood working tools, machine knives for the pulp, paper and metal working industries; measuring tools and plastic mould dies.

◆ Heat Treatment

Annealing

680 to 720°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 af ter annealing: Max. 220 HB.

Stress relieving

Approx. 650°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

790 to 820°C

Oil, salt bath (200 to 250°C) up to 20 mm thickness.

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 work piece 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.
