રાસાયણિક રચના (વજનમાં %)

વર્ણન:

Special cold work tool steel, air or oil hardenable with highest toughness.

એપ્લિકેશન્સ:

Forging tools, dies of all sorts, shapes and sizes, hot forging and pressing tools for steel and metal. Moulds, bushings, piercers, etc.

આસપાસના તાપમાને ભૌતિક ગુણધર્મો (સરેરાશ મૂલ્યો).

Modulus of elasticity [103 x N/mm2]: 210

ઘનતા [g/cm3]: 7.86

Soft Annealing：

610-850 ° સે સુધી ગરમ કરો, ભઠ્ઠીમાં ધીમે ધીમે ઠંડુ કરો. આ 295 ની મહત્તમ બ્રિનેલ કઠિનતા પેદા કરશે.

Stress Relieving：

Stress relieving to remove machining stresses should be carried out by heating to approx. 650°C, 

holding for 1-2 hours at heat, followed by air cooling. 

This operation is performed to reduce distortion during heat treatment.

Hardening：

Harden from a temperature of 880-910°C followed by air or oil quenching or warm bath quenching 180-220oC. Hardness after quenching is 56 HRC.

Tempering：
