Shanghai Metal Corporation is a professional manufacturer and supplier of Hastelloy C-4 products with high quality and reasonable price.
Hastelloy C-4 is an austenitic low-carbon nickel molybdenum chromium alloy. The main difference between Hastelloy C-4 and other early developed alloys with similar chemical compositions is their low carbon, silicon, iron, and tungsten content. This chemical composition makes it exhibit excellent stability at 650-1040 ℃, improving its ability to resist intergranular corrosion. Under appropriate manufacturing conditions, it can avoid blade line corrosion sensitivity and weld heat affected zone corrosion.
