EAF+LF+VD+(ESR), Forged, Black surface or Machined surface, UT 100% Passed

We offer two conditions of steel grade of 1.2083

Annealed: Hardness≤235HB

Q+T: Hardness 33-38HRC or as customized

◆ Characteristics

Martensite stainless steel, with good machincability and excellent corrosion resistance, polishability, and high strength and wear resistance after heat treatment.

◆ Applications

1. Components as axle, valve, gear, medical appliance, spring etc., which require high

    hardness and wear resistance.

2. For making plastic moulds and transparent plastic molds which require high load,

     wear resistance, and work under the action of corroding medium.

◆ Forging Technique

◆ Heat Treatment

840 to 870°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. 229 HB.

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.

1000 to 1050°C / Oil, air

Holding time after temperature equalization: 15 to 30 minutes.

Obtainable hardness: 53-56 HRC

100 to 200°C (212 to 392°F)

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.
