Low temperature embrittlement of stainless steel pipe --- in low temperature environment, the deformation energy is small. In the low temperature environment, the phenomenon that the elongation and area shrinkage decrease is called low temperature embrittlement. Most of them are produced on the body centered cubic structure of ferrite series.
There are three fundamental differences between 304 stainless steel and carbon steel. First, 304 stainless steel produces work hardening during cold working. For example, it has anisotropy during bending, that is, the transverse and longitudinal properties are different. The strength increased by cold working can be used, but if the bending area is small compared with the total area and this increase is ignored, the increased strength can improve the safety factor to a certain extent.
