1. 2507 full threaded stud bolt material introduction
S32750 is the standard grade of super-duplex stainless steel based on 25% chromium, 7% nickel and significant additions of molybdenum, manganese and nitrogen. As with many of the duplex grades, S32750 also offers high strength and excellent resistance to chloride stress corrosion cracking, while the molybdenum and nitrogen levels enhance the pitting, crevice and general corrosion resistance.
