NS338

Detail

NS338

Material grade: NS338 corrosion resistant alloy

US grade:/Hastelloy C-22( C22 UNS N06022)

German grade: W,Nr,2.4602

Overview

NS338/Hastelloy C-22 alloy   is a versatilenickel-chromium-molybdenum-tungsten alloy with better overall corrosionresistance than other existing nickel-chromium-molybdenum alloys, includingHastelloy C-276 , C4 and 625 alloys. Hastelloy C-22 alloy has excellentresistance to pitting, crevice corrosion and stress corrosion cracking. It hasexcellent resistance to aqueous solvents, including wet chlorine, nitric acidor a mixed acid of oxidizing acids containing chloride ions.

Application areas : It are used in a widerange of applications in the chemical and petrochemical industries, such as inthe contact with chloride-containing organic components and catalytic systems.This material is especially suitable for use in high temperature, inorganic andorganic acids (such as formic acid and acetic acid) and seawater corrosiveenvironments.
