In recent years. To solve the austenitic stainless steel to intergranular corrosion and stress corrosion problems candle bridge stainless steel wire, also took the development of ultra-low carbon stainless steel and super ferrite stainless steel. Currently, the species has been put into the stainless steel market has reached more than 230 kinds, frequently used there are nearly 50 kinds of stainless steel wire bridge where the good, 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. Stainless steel on the most important research and development is focused on two aspects: ◆ The first is to improve the corrosion resistance of steel, in which the 18-8 steel intergranular corrosion candle Issues of the bridge stainless steel wire business phone, not only the development of the steel is proposed to solve the question of the 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 aerospace structures used for stainless steel wire bridge Which deal, and have mass production, countries also have similar kinds of steel put into use. Their morphology can be divided into three categories: semi-austenitic precipitation hardening, precipitation hardening martensitic and precipitation hardening austenitic stainless steel. Included in China's national standard steel grades have 0Cr17Ni7A, 0Cr17Ni4Cu4Nb and 0Cr15Ni7M02Al are three half belonged precipitation hardening austenitic stainless steel. Organizational characteristics of the steel is an austenite plus a volume fraction of 5% to 20% of ferrite during solution or annealed condition. This series of steel after heat treatment or mechanical treatment after deformation of austenite into martensite, and then by aging precipitation hardening to achieve high strength required. This steel has good formability and good weldability, high strength materials can be used in the nuclear industry, aviation and aerospace industries, has been applied.
