S290 Steel

S290 Steel

Steel name: S290
Diagram No.: 2167
Chemical composition in weight %: 2.00% C, 0.50% Si, 0.30% Mn, 3.80% Cr, 2.50% Mo, 5.10% V, 14.30% W, 11.00% Co
Steel group: PM high speed tool steels
Properties: Segregation-free and homogeneous metal powders of highest purity and adequate granulation are processed to homogeneous and segregation-free high speed steels of virtually isotropic properties in a diffusion process taking place at high pressures and temperatures.
Applications: No data
Reference: Not shown in this demo version.

Heat Treatment
Hardening: 1150 to 1210°C (2102 to 2210°F) / salt bath. 1150 to 1190°C (2102 to 2174°F) / gas.
Tempering: Slow heating to tempering temperature immediately after hardening/time in furnace: 1 hour for every 20 mm of workpiece thickness, but not less than 2 hours/ air cooling (minimum holding time: 1 hour). 1st tempering and 2nd tempering to desired working hardness. Average obtainable hardness values are shown in the tempering chart. 3rd tempering for stress relieving, 30 - 50°C (86-122°F) below highest tempering temperature.
Diagram note: No data
