Heat Treatment of Wear Resistant Steels for Mud Pumps

Abstract:

Influence of different type heat treatment including high temperature quenching on wear resistance has been investigated. The two investigated steels are widely used in production of mud pumps. It was shown that Kh12MFL had better wear resistance in comparison with 150KhNML. Martensitic-carbide structure of the steels formed by quenching from high temperatures (900 – 1000 °С) induced good hardness (61 – 64 HRC). Analysis of the residual austenite contents influence on wear resistance was also made. It was determined that residual austenite formed after high temperature quenching (900 – 1000 °С) was metastable and had tendency to transform into carbon containing martensite of deformation. This allowed steels to have maximum wear resistance because of providing high abilities to friction hardening of the work place of the sample.
