The design rules for stainless steel cannot be used for carbon steel because there are three fundamental differences between stainless steel seamless steel tubes and carbon steel.

First, cold working stainless steel produces process hardening, for example, anisotropy in bending, i.e., different performance in the transverse and longitudinal directions. Can take advantage of the increased strength by cold working, but if the bending area is small compared to the total area and ignore this increase, the increased strength can improve the safety factor to some extent.

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

Third, stainless steel does not have a yield point, usually ó0.2 to express the yield stress is considered an equivalent value.
