Experimental Study on Degradation of 1Cr5Mo Steel Tubes in the Coking Furnace at Super Temperature

Abstract:

Article Preview

Microstructure, hardness and mechanical properties of the 1Cr5Mo steel tubes for the coking furnace at super temperature were investigated in this paper. It revealed that under super-temperature, oxidation corrosion for the furnace tubes was strengthened, wall thickness was evident thinner, pearlite in microstructure was spheroidised mostly, strength would be decreased and marked degradation in material occurred.
