In order to reduce the brittleness of the elbow, the quenched elbow is kept warm for a long time at a certain appropriate temperature higher than room temperature and lower than 650℃, and then cooled. This process is called tempering.First of all, we must choose what standard products to produce, cut the material, the simplest, that is, cut the pipe.(D is the diameter of the alloy elbow and R is the radius of curvature).
