Molybdenum is mainly used in iron and steel industry, generally more than 80% is added to the molybdenum in steel, only about 20% to produce metal molybdenum, molybdenum alloy, super alloy and special chemical products, they are mainly used in petroleum...

Stainless iron is a kind of stainless steel , the material mainly has 409, 410, 430, 444, which belongs to the martensitic and ferritic stainless steel, they will be attracted to a magnet. While the stainless steel can resist unity refers to the atmosphere...

Because the stainless steel pipe fittings in the chloride ion more widespread and corrosive medium environment, will destroy the surface passivation membrane, and formation of corrosion pits, combined with the surface of the part of the inclusions, poor...

Duplex stainless steel pipe is in the solution structure of ferrite in the microstructure and the austenite microstructure about each accounted for 50%, the less content usually have reached 30%, so the duplex stainless steel pipe with ferrite stainless...

With the rapid development of the domestic energy industry, application of stainless steel tube is rapidly increasing, the corrosion in oil and gas pipeline construction process, surface treatment of stainless steel tube is one of the key factors determining...

The performance of stainless steel is obtained by its special chemical composition, and the main element is chromium. The chromium and oxygen combine to form a dense chromium oxide film that protects the stainless steel pipe fittings from corrosion. When...

Now with the continuous development of the chemical industry in China, use of duplex stainless steel welded pipe is also increasing, the annual demand for Chinese duplex stainless steel tube in the rapid growth, and in the oil, urea and other industries...

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...

Now in the marine environment has a large number of stainless steel pipe materials and products, in order to adapt to all kinds of corrosion damage of the marine environment, we have developed a special type of stainless steel pipe, here to introduce...

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...
