Product Characteristics
Incoloy800 is a kind of austenitic heat-resistant alloy which is widely used in high-pressure structures at high temperature.The high strength of 800H alloy is mainly due to the addition of carbon, aluminum and titanium, and annealing at the lowest temperature of 1149 ° c to reach the grain size of ASTM5 or coarser. It has excellent corrosion resistance, stress corrosion resistance and processability in extremely high temperature water-based media up to 500 ° c
