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

Date:2019-01-09    View:300      Tag:Difference between Stainless Steel Thick-walled Seamless Tube and Carbon Seamless Steel Tube
The difference between stainless steel thick-walled seamless tubes and carbon seamless steel pipe mainly refers to the difference in design rules between stainless steel and carbon steel, that is, the design rules of these two types of steel are not common. The differences are summarized as follows: Stainless steel design rules cannot be applied to carbon steel because there are three fundamental differences between stainless steel and carbon steel pipe:


First, cold work hardening of stainless steel, for example, bending anisotropy, ie, horizontal and vertical properties are different. The strength can be increased by cold working, but if the bending area is smaller than the total area and the growth rate is negligible, the increase in strength can increase the safety factor to some extent. under these circumstances,


Second, the stress/strain curve of different shapes, the elastic limit of stainless steel is about 50% of the yield stress, and the minimum value is the standard. The yield stress value is lower than the yield value of carbon steel. under these circumstances,


Third, there is no yield point for stainless steel, which usually means that the yield stress at ó0.2 is considered to be equivalent.
