Designation by Standards
|Brand Name||Ravne No.||Mat. No.||DIN||EN||AISI|
Chemical Composition (in weight %)
Alloy special structural steel.
Cold forging steel grade used for stressed parts for machines, vehicles, quenched and tempered screws etc.
Physical properties (avarage values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: 210
Density [g/cm3]: 7.85
Heat to 650-720oC, cool slowly. This will produce a maximum Brinell hardness of 207.
Harden from a temperature of 830-870oC followed by water or oil quenching.
Tempering temperature: 540-680oC.
