Q235B spiral material chemical analysis

Spiral steel market demand is fast without chaos growth trend will not fundamentally change. Spiral steel market can not keep the changes in the chaos of rapid development hub depends on demand. Regulated macroeconomic policy level, the future will bring some market growth rate slows
The main raw material for the molten iron scrap steel, steel, sulfur and phosphorus content is higher than the high-quality carbon structural steel, general sulfur ≤0.050%, phosphorus ≤0.045%. Raw materials into steel by the other alloying elements such as chromium, nickel, copper, usually not more than 0.30%, according to the composition and performance requirements, such steel grades by the Q195, Q215A, B, Q235A, B, C, D, Q255A, B, Q275 and other steel-level representation.
NOTE: "Q" is the yield of "Qu" Hanyu Pinyin word uppercase first, followed by digital brands that minimum yield point (σs) value, followed by the symbol in accordance with the steel impurity element (sulfur, phosphorus) at levels ranging from high to low and accompanied by changes in carbon, manganese is divided into a, B, C, D four and so on.
GB700-88 standard carbon steel Q235 press metallurgical quality into A, B, C, D four grades, each grade of steel Si content of 0.3%. The difference is that carbon and sulfur, phosphorus content different. AB grade carbon content of 0.14% to 0.22% and 0.12% ~ 0.20%, CD grade carbon content of ≦ 0.18%, ≦ 0.17%, Mn-containing minimal amount of Class A, D grade minimum content of SP.
