Dachang hexagonal steel, cold drawn special-shaped steel, fixed length GCr15 hexagonal bar

GCr15 hexagonal bar is a kind of hexagonal steel of GCr15 material with specific length and specification, with high strength, high hardness, good wear resistance and fatigue resistance. After proper heat treatment, it can maintain high hardness at the same time, but also has a certain toughness, suitable for a variety of occasions with high material performance requirements.

The GCr15 hexagonal rod, which means that its length should be accurately controlled according to specific requirements, generally can achieve a high accuracy, such as ±1mm or even higher. At the same time, the size of the hexagonal can also be produced in strict accordance with the standards or customer requirements to ensure the consistency and interchangeability of the product.

GCr15 hexagonal bar usually adopts advanced production process, so that the surface finish is good, no obvious defects, not only beautiful, but also reduce the friction resistance generated in the process of use, improve corrosion resistance.

Choosing high-quality GCr15 as raw material, high-quality billets are more uniform in size, and their internal organizational structure is relatively stable, which provides the basis for the subsequent processing of high-precision hexagonal rods.

The initial forging temperature of GCr15 steel is generally 1050-1100 ℃, and the final forging temperature is not less than 850℃. Forging in this temperature range can ensure that the material has good plasticity, avoid the high temperature caused by grain growth, or the temperature is too low caused by forging cracks, thus affecting the dimensional accuracy of the hexagonal bar.
