Designation by Standards
Chemical Composition (in weight %)
Low alloyed cold working tool steel.
Tap drills, broaching tools, milling cutters and other cutting tools. It is usually supplied as silver steel.
Physical properties (avarage values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: 210
Density [g/cm3]: 7.80
Continuous Cooling Transformation (CCT) Diagram
Time-Temperature Transformation (TTT) Diagram
Heat to 680-710oC, cool slowly. This will produce a maximum Brinell hardness of 225.
Harden from a temperature of 810-840oC followed by oil quenching.Hardness after quenching is 63 HRC.
Tempering temperature: 180-300oC.
Hot forming temperature: 1050-900oC.
The machinability rating of D3 is roughly 25 % that of free machining carbon steel 1018. Due to its abrasion resistant nature, machining in the hardened condition should be limited to finish grinding.
