00Cr25Ni7Mo4N (S32750, F53, 2507, 1.4410) Super Duplex Stainless Steel Overview:

00Cr25Ni7Mo4N (S32750, F53, 2507, 1.4410) super duplex stainless steel is composed of 25% chromium, 4% molybdenum and 7% nickel. 00Cr25Ni7Mo4N dual-phase steel has strong strength and corrosion resistance, and is mainly used in chemical processing, petrochemical and subsea equipment. 00Cr25Ni7Mo4N duplex steel has strong resistance to chloride corrosion, higher thermal conductivity and lower thermal expansion coefficient. Higher chromium, molybdenum and nitrogen content it has a high resistance to pitting, crevice corrosion and general corrosion.

00Cr25Ni7Mo4N dual-phase steel also has high impact strength. It is not suitable for use in a temperature environment higher than 570 ° C. If it is exposed to such an environment for a long time, its toughness will decrease. 00Cr25Ni7Mo4N dual-phase steel also combines the most beneficial properties of many ferritic and austenitic steels. Due to the high chromium and molybdenum content of this steel, it has excellent resistance to pitting, crevice corrosion and uniform corrosion. The dual-phase microstructure ensures that the steel has a high resistance to stress corrosion cracking and high mechanical strength.
