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. Currently, the species has been put into the stainless steel market has reached more than 230 kinds, there are nearly 50 kinds of commonly used, of which about 80% (18 --8 chromium nickel) derivatives of austenitic stainless steel, while the rest 20% It is evolved from the 13 chrome steel made. The main research and development on stainless steels is focused on two aspects: ◆ The first is to improve the corrosion resistance of steel, in which the study of 18-8 steel intergranular corrosion candle problem, not only the development of steel grades It is 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 Shengyuan stainless steel wire contact, and the subsequent strengthening heat treatment (aging) is not high temperature deformation is small In the United States this steel used for aerospace structures, and have mass production, countries also have similar kinds of steel put into use. (1) Material: ①DDQ (deep drawing quality) material: refers to a material for deep drawing (Wash) use, that is, we called the soft material, the main characteristics of this material is higher elongation (≥53 %), low hardness (≤170%), internal grain grading between 7.0 to 8.0 Shengyuan stainless steel wire net price, excellent deep drawing properties. Many production thermos pot class enterprises, processing of their products than (BLANKING SIZE / products in diameter) are generally higher than Shengyuan stainless steel wire, they were up 3.0,1.96,2.13,1.98 than processing. SUS304 DDQ timber is mainly used for processing these requests higher than that of the product, of course, working ratio of more than 2.0 products are generally subject to few the stretch to complete. If the extension of terms of raw materials can not reach it, in the processing of deep-drawing products product easy to crack, pull through the phenomenon, affecting the rate of qualified products, of course, will increase the cost of manufacturers; ② general material: mainly used in addition to DDQ material applications outside the characteristics of this material are relatively low elongation (≥45%), while relatively high hardness (≤180) Shengyuan stainless steel wire service and good attitude, internal grain grade at 8.0 to 9.0, Compared with DDQ timber, its deep drawing performance is relatively marginal, it is mainly used in the products can be obtained without thrust, like a kind of tableware spoon, spoon, fork, electrical appliances, steel pipe uses. But it is compared with DDQ material has the advantage that BQ relatively good, mainly due to a slightly higher because of its hardness.
