Heat Treatment of Carbon, High-Chromium Steels for Mud Pump Liners of Drill Rigs and Drilling Equipment

Abstract:

The application of hardening heat treatment process at high temperatures (1100-1170 °C) for high-chromium steels of martensitic-carbide class 95Kh18 and Kh12MFL has been studied. Metallic substrate consisted of high-carbon martensite and residual metastable austenite with some traces of carbide has been obtained. Experiments have shown the resulting structure gains high frictional hardening capacity upon the application of heat. Sufficient amount of cooling martensite can be traced in the analyzed steel after high-temperature quenching (cooling up to the temperature of-70°С). Being combined with residual metastable austenite, it provides the increase of abrasive wear resistance by 25% compared with high temperature annealing. The influence of tempering temperature on hardness and abrasive wear resistance of analyzed steels 95Kh18 and Kh12MFL has also been determined.
