Pickling passivation of stainless steel pipes

Because of its excellent mechanical properties, high wear resistance and high hardness, the stainless steel pipe has been widely used in the processing of stainless steel pipes for military products. The surface treatment of stainless steel pipe is carried out after heat treatment, solid solution and aging, because the heat treatment process will produce thicker oxide skin […]

The principle of bright annealing of stainless steel tube

By eliminating the work hardening of the stainless steel tube, satisfactory metallographic structure can be obtained, and the process equipment is bright annealing furnace, which is mainly used for heat treatment of the finished stainless steel products under the protective atmosphere. When the stainless steel pipe performance requirements are different, the requirements of the microstructure after […]

Production process flow of hot rolled stainless steel tube

Hot rolling is rolling in stainless steel above the recrystallization temperature of the casting process, the organization will destroy the ingot, steel grain refinement, but also eliminate the defect microstructure of stainless steel, to make the organization more dense, improve mechanical properties. Such improvements generally reflected along the rolling direction, will make the stainless steel […]

How to determine the stainless steel plate

The surface of stainless steel plate is relatively smooth, the plasticity, toughness and mechanical strength are higher, to a certain extent, acid and alkaline gas solution or other corrosive media, is a kind of alloy steel is not easy to rust. Stainless steel plate has been widely used in chemical, food, pharmaceutical, papermaking, petroleum, atomic energy and […]

Polishing process of stainless steel pipe fittings

At present, there are many kinds of polishing processes for stainless steel pipe fittings. This paper introduces some common polishing processes, including mechanical polishing, chemical polishing, electropolishing, ultrasonic polishing, fluid polishing, etc.. Mechanical polishing Mechanical polishing on cutting and plastic deformation of plate surface is convex removed after polishing to obtain a smooth surface polishing method, […]
