Discussion on the heat treatment after head forming and the heat treatment test plates for heads
Thread Content
In RT, cold spinning, warm spinning, and hot spinning are primarily used for the forming of end caps. However, what kind of heat treatment is required after cold pressing or hot pressing for each type of end cap? And what are the regulations regarding whether heat treatment test pieces are needed when end caps are formed using warm spinning or hot spinning? What aspects are considered primarily? I would like to ask everyone for advice
There is a corresponding description in GB150. For those with a certain thickness and a deformation rate exceeding 5%, stress-relief heat treatment is required. If the hot forming process alters the heat-treated condition, a heat treatment to restore properties is required.
Agree with the opinion above; austenitic stainless steel is not included.
