Abstract
HECLA EM, 20 is an iron-nickel-cobalt-chromium austenitic alloy steel having high oxidation and scaling resistance. It is recommended for high temperature service and medium loads up to 2000 F, such as turbine blading, jet engine exhaust stacks and combustion chambers. This datasheet provides information on composition, physical properties, elasticity, and tensile properties as well as creep and fatigue. It also includes information on high temperature performance as well as forming, heat treating, machining, and joining. Filing Code: SA-204. Producer or source: Union Carbide Corporation (Licensor).
