1.2162 Steel

Steel name: 1.2162
Diagram No.: 2217
Mat.No. (Wr.Nr.) designation: 1.2162
DIN designation: 21MnCr5
AISI/SAE designation: 5120
Chemical composition in weight %: 0.21% C, 0.25% Si, 1.25% Mn, 1.20% Cr
Steel group: Case hardening steels
Properties: Standard steel for case-hardening with good machinability; high surface hardness with tough core.
Applications: Machine parts and moulding plates with a high surface hardness; synthetic resin press moulds for the processing of thermoplastics and thermosets.
Reference: Not shown in this demo version.

Heat Treatment
Hardening: Carburising: 900 to 950 °C. The choice of the carburising means and carburising temperature depends on the desired surface carbon content, the carburising graph and the required case depth. Case hardening: 870 to 930 °C in powder/salt bath, cooling in oil/hot bath at 160 to 250 °C. Intermediate heat treatment: 630 to 650 °C, for about 2 to 4 hours with slow furnace cooling. Hardening: Curing temperature 810 to 840 °C in warmed oil of ~ 60 °C. Cooling: in to about 100 °C oil, then in air to about 50 °C.
Tempering: 1 hour per 20 mm part thickness, min. 2 hours.
