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 -
