17Mn4 seamless steel pipe dimensional tolerance

 17Mn4 is a grade that complies with the DIN 17175 pipe specification standard, code: 1.0481. 17Mn4 seamless pipe is used as a heat-resistant pipe, and the working environment can reach a high temperature of 600 ° C. It is used to manufacture steam boilers, pipes and pressure vessels operating in high temperature environments.

The full length of the 17Mn4 steel pipe should be subjected to appropriate heat treatment. After hot processing, a uniform crystalline structure is produced. As far as 17Mn4 is concerned, it can be considered to meet the heat treatment requirements and meet the delivery standards.
