1.2746 45NiCrMoV16-6 Cold Work Tool Steel Round Bar
1.2746 45NiCrMoV16-6 Cold Work Tool Steel Round Bar is a high-quality cold work die steel with very high strength and hardness, which can perform well in a variety of heavy working conditions. The chemical composition of the steel is very accurately controlled, and the content of C, Si, Mn and P elements are within the ideal range, which can effectively improve the wear, heat and corrosion resistance of the steel. In addition, alloying elements such as Cr, Ni, Mo and V are added to the steel, which can improve the tensile strength, yield strength and ductility of the steel and extend its service life.
The 1.2746 45NiCrMoV16-6 Cold Work Tool Steel Round Bar can be used to produce various types of molds, tools, stamping parts, extrusions and bearings. Its high strength and high hardness can ensure that the parts do not deform, wear and break during long-term use. At the same time, the machining performance of the steel is also very good, can be easily cut, cold heading and quenching process operations, to obtain the ideal workpiece shape and performance characteristics.

Description
Special cold work tool steel, air or oil hardenable with highest toughness.
Applications
Forging tools, dies of all sorts, shapes and sizes, hot forging and pressing tools for steel and metal. Moulds, bushings, piercers, etc.
Physical properties (avarage values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: 210
Density [g/cm3]: 7.86
Soft Annealing
Heat to 610-850℃, cool slowly in furnace. This will produce a maximum Brinell hardness of 295.
Stress Relieving
Stress relieving to remove machining stresses should be carried out by heating to approx. 650℃, 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℃ followed by air or oil quenching or warm bath quenching 180-220℃. Hardness after quenching is 56 HRC.
Tempering
Tempering temperature: See the data bellow.
| Tempering Temperature (℃) | Hardness (HRC)) |
| 100 | 56 |
| 200 | 54 |
| 300 | 52 |
| 400 | 50 |
| 500 | 49 |
| 550 | 48 |
