The so-called seamless stainless steel pipe and carbon steel seamless pipe distinction, mainly refers to the difference in carbon steel and stainless steel design rules, which are a few differences are summarized as follows:
First, the stainless steel produced during cold work hardening, for example, anisotropic bending, namely: the different horizontal and vertical properties. You can utilize the increased strength of cold work, but if the bending of the smaller and this increase is negligible compared to the total area of increased strength can be improved to some extent, the safety factor.
Second, the stress / strain curves of different shapes, stainless steel elastic limit is about 50% of the yield stress, the minimum standards set forth in the terms of the yield stress values below the yield stress in carbon steel.
Third, there is no yield point steel, usually ó0.2 to represent the yield stress is considered to be equivalents
