The C22 alloy, which is developed on the basis of Hastelloy C276, is widely used in the near future.
C22 more than 276 localized corrosion, can be understood as an upgraded version of C276.
Two materials are also different:
C276 welding is NiCrMo-4; C22 welding is NiCrMo-10.
Through the different Cr and Mo content, the new C22 alloy gives a strong corrosion resistance.
C276 main ingredients: 57NI-16MO-16CR-5FE-4W-2.5CO-1MN-0.35V-0.08SI-0.01C
C22 main ingredients: 56NI-13MO-22CR-3FE-3W-2.5CO-0.5MN-0.35V-0.08SI-0.01C
