Designation by Standards
|Brand Name||Ravne No.||Mat. No.||DIN||EN||AISI|
Chemical Composition (in weight %)
Special structural steel.
Special purpose production. Parts of larger cross-sections where higher toughness is demanded, for gears, crankshafts, etc.
Physical properties (avarage values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: 210
Density [g/cm3]: 7.80
Heat to 620-660oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 255.
Harden from a temperature of 780-810oC followed by oil quenching or thermal bath at 180-220oC.
Tempering temperature: 150-180oC.
Hot forming temperature: 1050-850oC.
Forms manufactured: Please see the Dimensional Sales Program.
