Cylinder stress-relief heat treatment
Thread Content
In accordance with the requirements of 11.4.2 in standard JB/T4732, the material used is Q345R; for warm-forming cylinders, the nominal thickness is more than 3% of the inner diameter of the cylinder, and heat treatment is carried out after forming. Overall stress relief heat treatment is carried out on the cylinder, head, and other components after welding. Is it possible to avoid performing a separate heat treatment to restore the mechanical properties of the cylinder, and instead conduct only one overall stress-relief heat treatment after welding?
It can be combined with post-weld heat treatment, with the test pieces in the same furnace
