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