What are the factors that affect the strength of SA106 grade B seamless steel pipe

What are the factors that affect the strength of SA106 grade B seamless steel pipe?

SA106 grade B seamless steel pipe strength refers to the limit when SA106 grade B seamless steel pipe yields, that is, the stress that resists microplastic deformation. An external force greater than this limit will permanently invalidate SA106 grade B seamless steel pipe and cannot be restored.

The external factors that affect the strength of SA106 grade B seamless steel pipe are: temperature, strain rate, and stress state. As the temperature decreases and the strain rate increases, the strength of SA106 grade B seamless steel pipe increases, especially body-centered cubic metals are particularly sensitive to temperature and strain rate, which leads to low-temperature embrittlement of SA106 grade B seamless steel pipe. The influence of the stress state is also important. Although strength is an essential index reflecting the intrinsic properties of SA106 grade B seamless steel pipe, the stress state is different and the strength value is also different.
