S32750 super duplex steel threaded flanges has a good price advantage and cover most of the European and American markets. We look forward to becoming your long-term partner in China.
S32750 super duplex steel threaded flanges deformation energy only within the range of forming energy, Hebei Flange factory specializing in the production of national standard stainless steel flange cold forging simply to obtain excellent standard precision and appearance finish. As long as the temperature and smooth cooling are controlled well, the temperature forging below 700℃ can achieve excellent accuracy. In addition, attention should be paid to improving the working environment of hot forging. The die life (hot forging 2-5 thousand, warm forging 10-20,000, cold forging 20-50,000) is shorter than the casting in other temperature domains, but it has a large degree of freedom and low cost
