Hardening property of stainless steel elbow after welding

　　Stainless steel elbow processing is the production technology of product parts with certain shape, size and performance by means of the power of conventional or special stamping equipment, so that the sheet metal is directly subjected to deformation force and deformation in the die. Stainless steel elbow is easy to crack because of its high hardening after welding. Different electrodes are used to 316L Seamless Stainless Steel 4'' Pipe Fitting Elbow to ensure the quality of the stainless steel elbow. If the same type of chromium stainless steel elbow electrode is used for welding, it must be preheated above 300 ~C and slowly cooled after 700 ~C. If the weldment can not be heat treated after welding, the chromium-nickel stainless steel elbow should be selected. Different kinds of electrodes have different properties and characteristics in use. They are selected according to the corresponding needs to ensure the quality of welding stainless steel elbow.

　　Stainless steel elbow is a kind of good stainless steel elbow, which is widely used and popularized in different fields and industries, and has been applied and popularized to varying degrees.Stainless steel elbow is a kind of semi-circular elbow made of sheet metal with the same material as pipe by stamping die. Then two semi-circular stainless steel elbow are welded together. The welding of stainless steel elbow needs to be produced and processed in accordance with certain procedures. Due to the different welding standards of various types of pipelines, the semi-finished products are usually manufactured according to group-to-point solidification, and the field construction is carried out according to the weld grade of pipelines.
