Series & mdash; Heat resistant chromium alloy steel.Chinese brand cold rolled non oriented silicon steel strip (sheet) means: DW + times of iron loss value (at the frequency of Hz, the magnetic induction peak with sinusoidal waveform is the unit weight iron loss value of t) + times of thickness value. For example, dw- represents cold-rolled non oriented silicon steel with iron loss value of W / kg and thickness of .mm. Now the new model is W.Proper heat treatment process can prevent intergranular corrosion and obtain excellent corrosion resistance.For more, please check,The bright nickel layer on the stainless steel pipe is a silver white metal with slight yellow light. Its hardness is higher than that of copper, zinc, tin, cadmium, gold and silver, but lower than that of chromium and rhodium. Bright nickel has high chemical stability in air and good stability to alkali. Using Brightener on stainless steel pipe, bright nickel can be directly plated without polishing, so as to improve the hardness, wear resistance and leveling of the surface, make the appearance of stainless steel pipe consistent with other nickel plated parts and avoid the corrosion of potential difference between stainless steel pipe and other bright nickel. After using bright nickel solution for a period of time, due to the of brightenerFor more than years, architects have been using stainless steel to build cost-effective buildings. Many existing buildings fully illustrate the correctness of this choice. Some are very ornamental such as the Chrysler Building in New York City. However, in many other applications, the role of stainless steel is not so eye-catching, but in the aesthetics and performance of buildings For example, because stainless steel has more wear resistance and pressure resistance than other metal materials of the same thickness, it is the preferred material for designers when building sidewalks in places with large population flow.Model & mdash; The corrosion resistance is the same, and the strength is better because the carbon content is relatively high.

The main way to prevent stress corrosion of austenitic stainless steel is to add SI ~ % and keep the content of N below .% from smelting. In addition, the content of impurities such as P, Sb, Bi and as should be reduced as much as possible. In addition, which does not correspond to stress corrosion in Cl - and oh - media. The initial micro crack will not continue to expand after encountering ferrite phase and the ferrite content should be about % .Installation requirements,Restate the quality of stainless steel pipe such as stainless steel pipe, we promise & ldquo; chromium and nickel & rdquo; Penalty for false and provide quality inspection report and certificate of conformity.At this time, we usually answer directly: no! What we produce is stainless steel decorative pipe which belongs to stainless steel slotted pipe. It can not be used as stainless steel water pipe. If you want to choose stainless steel water pipe, you must choose stainless steel pipe.The accumulation of organic impurities caused by decomposition products and the pollution of some other metal impurities. There is no turnover of long-term stainless steel plate, stainless steel coil, stainless steel belt and stainless steel pipe to avoid price difference. The price is % higher than the market price! The price of more than one ton is higher! So that the nickel bath can not get the ideal bright nickel coating, it is necessary to carry out large-scale treatment. In the solution of bright nickel plating on stainless steel pipe, the brightener has developed rapidly and has many varieties. To sum up, the development of brighteners has experienced four generations. Instead of the original product, saccharin and butynediol can be plated with bright nickel with high flatness. Its application flourished in the s and s. It seems that due to the instability of butynediol in the nickel plating bath, short service life and rapid accumulation of organic impurities, the nickel bath needs to be treated frequently. Therefore, epoxy chloropropyl or epoxy is branched with butynediol to synthesize the second-generation nickel plating brightener, such as b brightener. The situation has improved. Be and retain alkynyl. Later, pyridinyl is polymerized to form the third-generation product, Faster light output, less amount of brightener and longer service life. Now it further uses various combinations of nickel plating brightener intermediates to form a new brightener, which has developed to the fourth generation of products. It has less use, faster light output speed and longer treatment cycle.
