The difference between stainless steel seamless pipe and carbon steel seamless tube

Stainless steel Seamless pipe production companies are aware that the so-called stainless steel seamless pipe and carbon steel seamless pipe differences, mainly refers to the difference between the stainless steel and carbon steel planning rules, that is to say, the two kinds of steel planning rules can not be universal. The differences are as follows:


First, the cold processing of stainless steel processing hardening, for example, zigzag with anisotropy, that is: horizontal and vertical functions are different.


Can use the strength increased by cold processing, but if compared with the total area of the tortuous area is small, ignoring this addition, the increase in strength can be to a certain extent improve the safety factor. Second, the stress/strain curve shape is different, the elastic limit of stainless steel is about 50% of the yield stress, the minimum value of the rule in the norm, the yield stress value is lower than the yield stress value of medium carbon steels. Three, stainless steel does not yield point, usually Ó 0.2来 show that the yield stress is considered equivalent value.
