UNS N08800(NAS 800L)

Product : UNS N08800（NAS 800L）

NAS 800L Nickel base alloy is in chloride environments with excellent corrosion resistance of the alloy. NAS 800H has good high corrosion resistance, also for acid-resistant steel. NAS 800T i maintained at a good high temperature strength, corrosion resistance and oxidation resistance of high heat-resistant nickel steel, characterized by maintaining a high degree of microstructural stability at high temperatures. Is by high temperature heat treatment of the grain size and the C (carbon), Ti (titanium), control Al (aluminum) content of the obtained high creep strength.

NAS 800 (NCF 800, UNS N08800) - comparable with Incoloy® 800 alloy - is a high-nickel heat-resistant steel, high temperature environments with good strength and corrosion resistance, oxidation resistance. Component tissue close to the austenitic stainless steel, Inconel® alloy and having equivalent characteristics.
