Processing Technology of 316 Stainless Steel for Foreign Trade Products

Q1: What welding methods are suitable for 316 stainless steel? A1: It has excellent weldability and is suitable for all standard fusion welding methods, such as argon arc welding, manual arc welding and submerged arc welding.

Q2: What should be paid attention to when welding 316 stainless steel? A2: It is necessary to control the heat input to prevent sensitization; 316 thick-walled parts need annealing after welding to obtain the best corrosion resistance, while 316L does not need it.

Q3: What welding materials are recommended for 316 and 316L stainless steel? A3: It is recommended to use matching welding materials, such as ER316 welding wire for 316 stainless steel and ER316L welding wire for 316L stainless steel.

Q4: Can 316 stainless steel be processed by bending, rolling and other forming operations? A4: Yes, it has good formability and is easy to carry out bending, rolling, stamping and other forming operations, which is suitable for the production of various shaped products.

Q5: What is the heat treatment method of 316 stainless steel? A5: The main heat treatment method is solution treatment (annealing), which is heated to 1010-1120℃ and cooled rapidly to ensure its mechanical properties and corrosion resistance.
