Product Description
Stainless steel elbow
1. When using the electrode, it should be kept dry. The Ti-Ca type should be dried at 150 C for 1 hour. The low hydrogen type should be dried at 200-250 C for 1 hour (it can not be repeatedly dried, otherwise the coating is easy to crack and peel), so as to prevent sticking oil and other dirt on the electrode coating, so as to avoid increasing the carbon content of the weld and affecting the quality of the weld. Carbides are precipitated by repeated heating during elbow welding, which reduces corrosion resistance and mechanical properties. It is easy to crack because of its high hardness after welding. If the same type of electrode is used for welding, it must be preheated above 300 ~C and slowly cooled around 700 ~C after welding. If the weldment can not be heat treated after welding, chromium-nickel stainless steel electrode should be selected.
2. In order to improve the corrosion resistance and weldability of stainless steel elbows, appropriate addition of stability elements Ti, Nb, Mo, etc. can make the weldability better. When using the same type of chromium stainless steel welding rod, preheating above 200 C and tempering around 800 C after welding should be carried out. If the weldment can not be heat treated, chromium-nickel stainless steel electrode should be selected.
