20th of July ,2021

Stainless steel seamless pipes and carbon steel seamless pipes are widely used in industry.

1. Stainless steel produces work hardening during cold working, for example, it has anisotropy when bent, that is, the transverse and longitudinal properties are different. The increased strength by cold working can be used, but if the bending area is small compared to the total area and this increase is neglected, the increased strength can improve the safety factor to a certain extent.

2. The shape of the stress/strain curve is different. The elastic limit of stainless steel is about 50% of the yield stress. As far as the small value specified in the standard is concerned, the yield stress value is lower than that of medium carbon steel.

3. Stainless steel has no yield point. Usually, 60.2 is used to indicate that the yield stress is regarded as the local value.
