Difference between Stainless Steel Seamless Pipe and Carbon Steel Seamless Pipe

The so-called difference between stainless steel seamless pipe and carbon steel seamless pipe, stainless steel and carbon steel mainly refers to the difference in the design rules, that is, the design rules of these two types of steel are not universal.
These differences are summarized as follows: The design rules of stainless steel can not be used for carbon steel because there are 3 fundamental differences between stainless steel and carbon steel:

First, when cold working stainless steel produce work hardening, for example, when bending anisotropy, namely: the horizontal and vertical performance are different. The strength increased by cold working can be utilized, but if the bending area is small compared to the total area and negligible, the increase in strength can improve the safety factor to a certain extent.

Second, the shape of the stress / strain curve is different. The elastic limit of stainless steel is about 50% of the yield stress. The yield stress is lower than the yield stress of medium carbon steel in terms of the minimum specified in the standard.

Third, stainless steel does not yield point, usually ó0.2 that yield stress is considered equivalent.
