Nicrofer 5923 hMo is a nickel-chromium-molybdenum alloy with extremely low silicon and carbon content, excellent corrosion resistance and high mechanical strength.

Features


1, Excellent corrosion resistance to most corrosive media under oxidizing and reducing conditions.
2, Excellent resistance to pitting, crevice corrosion and chloride-induced stress corrosion cracking
3, Excellent resistance to inorganic acids such as nitric acid, phosphoric acid, sulfuric acid and hydrochloric acid,    specially mixed acids of sulfuric acid and hydrochloric acid
4, Excellent resistance to corrosion of various inorganic acid mixed solutions
5, Good corrosion resistance in various concentrations of hydrochloric acid Rongyi in up to 40 ° C (104 ° F)
6, Good processability and weldability, no post-weld cracking sensitivity
7, Manufacturing certification for pressure vessels with wall temperatures between -196 and 450 °C

Metallographic Structure


Nicrofer 5923 hMo is a face-centered cubic crystal structure

Characteristic


Nicrofer 5923 hMo, a nickel-chromium-molybdenum alloy with extremely low carbon and silicon content, has no tendency to precipitate out of impurities during hot working and welding. Therefore, it is suitable for various chemical processes containing oxidizing and reducing media to be higher than other Ni-Cr- Mo stainless steel. NIcrofer 5923 hMo is more than three times less corrosive in some reducing environments (such as boiling 10% sulfuric acid) than conventional Ni-Cr-Mo stainless steel, and is also suitable for the chemical process industry in reducing environments. Shows the excellent corrosion resistance of Nicrofer 5923 hMo in hydrochloric acid. Alloy materials have the best corrosion resistance only in the proper metallographic state and pure crystal structure.

Applications


1, When using an acid chloride catalyst
2, Digesters and bleaching equipment in the pulp and paper industry
3, Scrubbers, reheaters, throttle valves, temperature and humidity fans, stirrers, etc. in FGD and IG systems
4, Equipment and components operating in an acid gas environment
5, Reactor for acetic acid and acetic anhydride products
6, Sulfuric acid condenser
