The influence of heat treatment process on the microstructure and mechanical properties of 2Cr12NiMoWV steel was studied. The results show that the steel can achieve good strengthening and toughening effects when quenched at 1055-1070 ℃ and tempered at 700-710 ℃. And based on this, the heat treatment process specific...

1、 During the manufacturing process of pressure vessels, the following issues will arise: cold work hardening caused by excessive cold rolling, cold straightening, and other cold processing. Changes in the microstructure and properties of the weld zone caused by welding. The generation and development of residual stre...

Chromium element is a factor that makes such materials rust resistant. Previously, it was found that chromium content must be above 12% to form a dense surface oxide film and achieve corrosion protection. Therefore, any heat treatment of stainless steel must consider whether it will cause any changes in the composition...
