W.Nr. 2.4819 is a nickel-chromium-molybdenum-composite-gold containing tungsten with extremely low silicon and carbon content.

Widely used in the chemical and petrochemical industries, such as in the contact with chloride-containing organic components and catalytic systems. W.Nr. 2.4819 is especially suitable for use in high temperature, inorganic acids mixed with impurities 

W.Nr. 2.4819 is an improved Hastelloy c wrought form developed in 1968 by HAYNES INTERNATION-ALINC, which is widely used in highly corrosive media. It is a tungsten-containing nickel-chromium-molybdenum alloy with a little silicon carbon content and is considered as a versatile corrosion resistant alloy. The main moisture-resistant chlorine, a variety of oxidizing chlorides, chloride salt solution, sulfuric acid and oxidizing salts, have good corrosion resistance in low temperature and medium temperature hydrochloric acid.
