Difference between Stainless Steel Pipe and Carbon Seamless Steel Pipe

The so-called difference between stainless steel seamless pipe and carbon steel seamless pipe, mainly refers to the stainless steel and carbon steel in the design rules of the differences, that is, these two kinds of steel design rules are not common.

Stainless steel design rules can not be used for carbon steel because there are three fundamental differences between stainless and carbon seamless steel pipe.
First, the cold work of stainless steel to work hardening, for example, when bent with anisotropy, namely: horizontal directional and vertical performance are different. The strength increased by cold working may be utilized, but if the bending area is smaller than the total area and the increase is negligible, the increase in the strength may increase the safety factor to a certain extent. In this case,

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

Third, there is no yield point of stainless steel, usually expressed in ó0.2 to the yield stress is considered to be equivalent.
