TECHNICAL DATA SHEET of Creep-resisting Steel - Grade 1.4940
MATERIAL CATEGORY: Austenitic creep-resisting steels
FEATURES AND CLASSIFICATIONS
Heat-resistant steel means one type of steel possesses inoxidizability, enough high-temperature strength and excellent heat-resistant quality under high temperature. Heat resistant steel is divided into oxidation resistant steel and refractory steel according to its performance. Further into Austenitic heat-resistant steel, Martensitic heat-resistant steel, Ferritic heat-resistant steel and Pearlitic heat-resistant steel according to its normalizing.
