2205 stainless steel tube and 316L stainless steel pipe purchase, the researchers found that the steel in the Cr and Cu superposition effect, can further enhance the Cr on the passivation of the film and the corrosion of steel again after passivation. Based on this finding, JFE’s TOMOHIROISHII et al. Developed a new ferrite stainless steel JFE443CT, which has comparable corrosion resistance to TYPE304 in neutral chloride environments.
In addition, since Ni and Mo were not added, the price was also very stable when nickel and molybdenum prices fluctuated violently. As JFE’s R & D personnel expected, as a replacement for TYPE304, the newly developed JFE443CT is becoming a "omnipotent" material that is widely used in kitchen appliances, household appliances, knives, interior and exterior buildings, automotive exhaust systems Parts and other uses.
310S stainless steel pipe is a hollow long circular steel, mainly used in petroleum, chemical, food, light industry, mechanical instruments and other industrial pipelines and mechanical structural components. In addition, the bending, torsion strength of the same, the lighter weight, it is also widely used in the manufacture of mechanical parts and engineering structure. Also used for the production of conventional weapons, barrels, shells and so on. Stainless steel export is an important part of China’s export economy, it has an important role in stimulating China’s economic growth, but from the current situation of China’s stainless steel trade, China’s stainless steel exports encountered greater resistance.
2205 stainless steel pipe is divided into ordinary carbon steel pipe, high quality carbon structural steel pipe, alloy structure pipe, alloy steel pipe, bearing steel pipe, stainless steel tube and precious metals to meet the special requirements and meet the special requirements of the double metal composite pipe, Wait. A wide range of stainless steel tube, use different, its technical requirements vary, the production method is also different. The current production of steel pipe diameter range of 0.1-4500mm, wall thickness range of 0.01 ~ 250mm.
