In recent years. To solve the intergranular corrosion and stress corrosion problems candle austenitic stainless steel, and are developing a low carbon stainless steel and super ferrite stainless steel. At present, Shenzhen 304 stainless steel spring wire, stainless steel varieties have been placed on the market has reached more than 230 kinds, there are nearly 50 kinds of commonly used, of which about 80% are austenitic stainless steel (18 Cr --8 nickel) derivatives The remaining 20% ??is made up of 13 evolved from the chrome steel. The main research and development on stainless steels is focused on two aspects: ◆ The first is to improve the corrosion resistance of 304 stainless steel spring wire, where the study of 18-8 steel intergranular corrosion candle problem, not only the development of special hard steel 304 stainless steel spring wire, proposed to solve this question process method. Also it promotes research related to the mechanism of passivation and corrosion of stainless steel. ◆ The second aspect is the development of high strength stainless steel (ie precipitation hardening stainless steel), this steel is after World War II with the development of aviation, aerospace and rocket technology and developed. Wherein the semi-austenitic precipitation hardening stainless steel has excellent processing performance (17-7PH class), easily forming process after solution treatment, and the subsequent strengthening heat treatment (aging) is not high temperature deformation is small, the steel in the United States used for aerospace structures, and have mass production, countries also have similar kinds of steel put into use. How to solve the problem in general stainless steel Pipes Rusty Pipes mainly manufacture material is stainless steel, stainless steel Pipes rust caused mainly because the average break carbon steel with atmospheric oxygen reacts with the metal surface an oxide film, and then proceed to oxidation, corrosion continued to expand, forming corrosive "Lapis" type until rotten wear. However, people will make use of in order to avoid corrosion of paint or oxidation-resistant metal (such as zinc, nickel and chromium) plating to protect the steel surface, however, this protection is only the protective layer is a layer of film, if the protective layer is damaged, The following steel began to rust right again. Resulting stainless steel Pipes rust. 304 stainless steel spring wire | Shengyuan Stainless | 304 stainless steel spring wire manufacturer provided by the Dongguan City Shengyuan Stainless. 304 stainless steel spring wire | Shengyuan Stainless | 304 stainless steel spring wire factory in Dongguan City Shengyuan Stainless Steel Co., Ltd.
