seamless stainless steel tube and carbon steel seamless steel pipe

The difference between stainless steel seamless steel pipe and carbon steel seamless steel pipe mainly refers to the difference in design rules between stainless steel and carbon steel, that is to say, the design rules of these two kinds of steel are not universal. These differences are summarized as follows:


Stainless steel design rules cannot be applied to carbon steel because there are three fundamental differences between stainless steel and carbon steel:


Firstly, the stainless steel hardens during cold working, for example, it has anisotropy when bending, that is, the transverse and longitudinal properties are different.

Strength can be increased by cold working, but if the bending area is smaller than the total area and the increase is ignored, the increase in strength can improve the safety factor to a certain extent.

Secondly, the elastic limit of stainless steel is about 50% of the yield stress, which is lower than the yield stress of medium carbon steel.

Thirdly, stainless steel has no yield point. Usually, the yield stress is expressed as "0.2".
