W.1.2085 | X33CRS16
Corrosion-resistant, pre-hardened mould steel with high strength. Good machinability and high strength without subsequent heat-treatment. Steel 1.2085 is a high-hardness steel grade that can be hardened to a Rockwell hardness of up to 56 HRC, making it suitable for use in applications where high levels of hardness are required. Despite its high hardness, 1.2085 grade steel exhibits good toughness, making it resistant to chipping and cracking.

Heat Treatment
W 1.2085 steel is delivered quenched and tempered to a hardness range of 280/325 HB. Subsequent heat treatment is therefore generally not necessary.
Soft annealing:
850 to 880 °C for about 2 to 5 hours
slow controlled cooling, further cooling in air, annealing hardness max. 240 HB
Hardening:
1000 to 1030 °C
keeping curing temperature for 30 minutes
quenching in oil is preferable
obtainable hardness: 48 HRC
Tempering:
Tempering temperature depends on the required
mechanical properties.
In a general way, the following instructions must be
taken into account:
> uniform heating to the selected temperature
> soaking for one hour per inch of total thickness
> double tempering with cooling to room temperature
Applications
Plastic Molds and Dies: 1.2085 steel is extensively used in the manufacturing of plastic molds and dies due to its high hardness and wear resistance properties.
Automotive and Aerospace Components: such as engine parts, suspension components, and landing gear components.
Medical Equipment: such as surgical instruments and dental tools.
Cutting Tools:such as knives and blades.
General Engineering Applications: such as shafts, gears, and bearings, where its high hardness and wear resistance properties are required.
