UNS S32750 super duplex steel consists of 25% chromium, 4% molybdenum and 7% nickel. It has high strength and corrosion resistance and is mainly used in chemical processing, petrochemical and subsea equipment. It has strong resistance to chloride corrosion, high thermal conductivity and low thermal expansion coefficient. The high chromium, molybdenum and nitrogen content makes it highly resistant to pitting, crevice and uniform corrosion. The grade standard of S32750 is as follows:
| Standard | UNS S32750 | DIN/EN 1.4410 | ASTM A240/SA240M |

S32750 Advantages
-
Corrosion resistance: The high chromium and molybdenum content in S32750 makes it have strong overall corrosion resistance to organic acids such as formic acid and acetic acid. Compared with 904L, SAF2507 has stronger corrosion resistance.
-
Heat treatment ability: S32750 should be solution annealed and quenched after hot or cold forming. The temperature of solution annealing should not be lower than 1052°C, and air or water cooling quenching should be performed immediately afterwards.
-
Welding performance: S32750 has good weldability and can be welded by the following methods: SMAW, GTAW, PAW, FCW, SAW.
