rolls for cold formed steel

Rolls are an important tool for the production of welded pipes and cold-formed steel. Our company adopts German COPRA software design, which combines the design advantages of the United States, Japan and other countries, combines the characteristics of the forming unit, and carries out the 5-step and 4-level design of the roll. The round pipe design uses the internationally advanced "W" hole type", "F-F" combination hole, which can be directly square or rounded.

Product performance index:

1.Material: Cr12；GCr15；Cr12Mo1V1; Cr12MoV；9Cr2Mo；3Cr2W8V；40Cr；86CrMoV7, high chromium alloy
2. Working surface hardness HRC58-62

3. Deep hardened layer , can be used for secondary repair

The surface precision can reach international standards after grinding by treatment.

Rolls can be customized according to your needs,for example different models, specifications and materials.
