The difference between the so-called stainless steel seamless steel pipe and the 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 the two steels are not universal. The differences between the seamless tubes are summarized as follows: Stainless steel design rules cannot be used for carbon steel because there are three fundamental differences between stainless steel and carbon steel: First, the stainless steel is work hardened during cold working, for example, it has anisotropy when bent, that is, the lateral and longitudinal properties are different. The strength increased by cold working can be utilized, but if the bending area is small compared to the total area and the increase is neglected, the increase in strength can improve the safety factor to some 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 value of the yield stress is lower than the value of the yield stress of the medium carbon steel in terms of the minimum value specified in the standard. Third, stainless steel has no yield point, and it is usually indicated by ó0.2 that the yield stress is considered to be an equivalent value.
