Abstract
Weldability and creep rupture strength of a new low-carbon chromium steel of the ferritic class at elevated temperatures were investigated. Compared to the known P91 steel, the new steel is further alloyed with tungsten. Investigations demonstrated that E911 steel is not inferior to P91 steel in weldability, while the creep rupture values of E911 steel welded joint are higher than those of P91 welded joint.
Keywords: ferritic stainless steels, E911 steel, weldability, creep strength, microstructure
