Carlson Alloy C800 AT has superior creep and rupture strengths over long-term exposure to high temperatures and higher ASME boiler and pressure-vessel design stress allowables than C800 H. The alloy resists stress-corrosion cracking, resists sulfur attack, internal oxidation, scaling and corrosion in thermal processing and heat-transfer applications. The strength is obtained by a selective chemistry range within that of Alloy C800 H. This datasheet provides information on composition, physical properties, elasticity, and tensile properties as well as creep. Filing Code: Ni-459. Producer or source: G.O. Carlson Inc.
