Designation by Standards
|Brand Name||Ravne No.||Mat. No.||DIN||EN||AISI|
Chemical Composition (in weight %)
Alloyed carbon steel.
Screws, severely stressed engine and machine parts.
Physical properties (avarage values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: 210
Density [g/cm3]: 7.85
Heat to 680-720oC, cool slowly. This will produce a maximum Brinell hardness of 223.
Harden from a temperature of 830-870oC followed by water or oil quenching.
Tempering temperature: 540-680oC.
Hot forming temperature: 1050-850oC.
Forms manufactured: Please see the Dimensional Sales Program.
