U.S.A2205 stainless steel stripTen common sense

The intergranular corrosion of austenitic stainless steel can be prevented by adding Ti, Nb and other elements that can form stable carbides (tic or NBC) and avoiding the precipitation of cr23c on the grain boundary.

When the chromium content reaches 5%, the atmospheric corrosion resistance of the steel increases significantly, but when the chromium content is higher,U.S.ACold rolled stainless steel coil, the corrosion resistance can still be improved, but it is not obvious. The reason is that when the steel is alloyed with chromium, the type of surface oxide is changed to be similar to that on pure chromium metal

U.S.A.A diffusion layer is formed on the surface of the material to improve the wear resistance of the material, which is combined with Cr and chemical stable phase 07-fe3n

Production process of stainless steel welded pipe: raw materials -- strip splitting -- welded pipe making -- end repair -- polishing -- Inspection (spray printing) -- Packaging -- shipping (warehousing) (decorative welded pipe).

.Why is the stainless steel plate bellows compensator in the hot smoke compensator? The inner cavity of the stainless steel plate bellows compensator is bright and clean. After specific testing, it has no harm to the material flow speed and total flow, and it is not rusty. According to the soft deformation of the metal bellows, the stainless steel plate bellows shall be compensated

The following four methods are used for backing welding.

In this process, the following key points should be paid attention to: during the welding process, the correct included angle should be maintained between the welding handle, welding wire and weldment, and the ideal rake angle of the welding handle nozzle is 70 DEG& Mdash; 80°,U.S.A301 high quality stainless steel pipe, The included angle between the welding wire and the surface of the weldment is 15 DEG& Mdash; 20°; Correct weld pool temperature and change welding

How to correctly distinguish 304 and 201 stainless steel plates?

The folded stainless steel hot rolled strip is hot rolled into a strip with a thickness of 80mm-00mm and a width of 50mm-1200mm.

Stainless steel plate can be cut 20mm thick, and supports cutting A-type groove, V-type groove, Y-type groove, X-type groove and K-type groove. For example, for a 20mm thick steel plate, if the beveling machine is used, the beveling of one side takes about 40-50 minutes, which consumes a lot of time and labor costs

Product line.Water quality requirements. Therefore, relevant experts: building water supply pipes will eventually return to the era of metal pipes. According to the application experience of foreign countries, thin-walled stainless steel pipe is recognized as one of the pipes with good comprehensive performance.

It is possible for 310 to rust in an acid corrosive environment but it is impossible to rust in a short time in an ordinary environment. Therefore, the speed of rusting depends on the environment and the air environment with strong acidity and alkalinity. Rusting at the seaside is faster than inland.

All metals react with oxygen in the atmosphere to form oxide films on their surfaces. Unfortunately,

Different

Trustworthy.No. When the initial micro crack meets the ferrite phase, it will not continue to expand, coloring solution temperature which is isolated from the corrosion resistance of oxygen invaded in the steel.

U.S.A.A proper amount of MnSO4 was added with CrO3 and H 2SO 4H2O as the main components 4H2O coloring solution was used for chemical coloring of stainless steel industrial pipe. The effects of pretreatment process, mass concentration and coloring time on the color film of stainless steel industrial pipe were discussed.

Why does the stainless steel plate bellows compensator use the technology of primary hydraulic press forming and mechanical equipment forming in the hot smoke compensator stainless steel plate bellows compensator, assisted by computer reliability design, production and manufacturing, clean and non-invasive surface and good commodity structure

According to the purpose,U.S.A304L stainless steel coil, the application classification can be divided into oil well pipe (casing, oil pipe and drill pipe), pipeline pipe, boiler pipe, mechanical structure pipe, hydraulic prop pipe, gas cylinder pipe, geological pipe, chemical pipe (high-pressure fertilizer pipe, petroleum cracking pipe) and marine pipe
