Difference between Stainless Steel Thick-walled Seamless Tube and Carbon Seamless Steel Tube

Difference between stainless steel thick-walled seamless tube and carbon seamless steel pipe, mainly refers to the stainless steel and carbon steel in the design rules of the differences, that is, the design rules of these two kinds of steel is not common. These differences are summarized as follows: Stainless steel design rules can not be used for carbon steel because there are three fundamental differences between stainless steel and carbon steel:

First, the cold work of stainless steel to work hardening, for example, bending anisotropy, that is: the horizontal and vertical performance is 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 specified in the minimum value, the yield stress value is lower than the yield value of 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.
