AB Materials for parts which are subjected to abrasive wear in service are typically selected on the basis of the microstructure type and hardness. Additional characteristics, such as grain size and the size and morphology of carbides are considered less frequently, although they may prove very important. This article deals with treatment cycles which combine an unconventional forming technique and subsequent heat treatment and explores its impact on abrasive wear resistance in X210Cr12 tool steel. Effects of microstructure refinement prior to and during forming and during heat treatment are described. The forming cycle involved semi-solid processing and was followed by quenching. This sequence refined the initial microstructure and altered the morphology of chromium carbides. The semi-finished products were then cryogenically treated at 160°C for 24 hours and in some cases, subsequently tempered at 300°C for 2 hours. Their wear resistance was tested by blasting and the relationship between the treatment and the weight loss in the test was assessed.
