Commonly used cold-working forming methods for stainless steel
(1) Cold bending: Cold bending is widely used to make parts from stainless steel sheets and strips. Punch presses are open single-acting, mechanically or hydraulically driven, with a long and narrow workbench. This machine can only produce straight parts, but skilled tool designers can also use i...Read more -
Under what circumstances can stainless steel pipe fittings be welded with argon arc and under what circumstances can arc welding be used
1. Argon arc welding is a welding technology that uses argon as a protective gas. Also called argon gas-shielded welding. It is to pass argon protective gas around the arc welding to isolate the air from the welding area and prevent oxidation of the welding area. Argon arc welding technology is b...Read more -
Classification of welded steel pipes and the uses and advantages of different welded steel pipes
Welded steel pipes can be classified into different types and types according to different classification methods. Welded steel pipes of different properties have different characteristics and characteristics in use and show different use values in use. Welded steel pipes can be divided into the ...Read more -
Solutions to rust spots on stainless steel elbows
There will be rust spots on the stainless steel pipe elbow, which means that the elbow is not made of pure stainless steel, but an electroplated stainless steel elbow. The rust spots can be polished with ultra-fine sandpaper and then sprayed with colorless varnish for anti-rust treatment. It is r...Read more -
Why stainless steel pipes need solution annealing treatment
Austenitic stainless steel is softened by solid solution treatment. Generally, the stainless steel pipe is heated to about 950 to 1150°C, and kept for some time, so that the carbides and various alloying elements are fully and evenly dissolved in the austenite, and then quickly quenched to cool. ...Read more -
Methods and annealing steps for preheating deformation of straight seam steel pipes
Methods for preheating deformation of straight seam steel pipes: 1. Reasonable material selection. For precision complex molds, micro-deformation mold steel with good quality should be selected. Mold steel with serious carbide segregation should be reasonably cast and subjected to quenching and t...Read more
