Delivery Condition
EAF+LF+VD+(ESR), Forged, Unmachined or Machined surface, UT 100% Passed
We offer two conditions as
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.
 
Application
It is also widely used for making plastic moulds and transparent plastic molds which require high load, wear resistance, and work under the action of corroding medium.

Temperature

Cooling Method

Slowly heat to 800°C,
then quickly heat to finaL forging temperature

1160 - 1200°C

>=850°C

Ash coolinor sand cooling, with timely annealing
 
Heat Treatment
Annealing
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.
           
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
1000 to 1050°C / Oil, air
Holding time after temperature equalization: 15 to 30 minutes.
Obtainable hardness: 53-56 HRC
 
Tempering
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.
What we can offer?
 
We offer a wide range of steel products in a wide variety of dimensions and executions, acc.to the common international specifications or customerized.
Machining and heat treatment are available.
Also, we advise you in choosing the right materials.
