Purpose: CrN coating, hard chrome plating and nitriding has been applied on commonly used thermoset plastic mould steel X40CrMoV5-1 (Materials number 1.2344). The effects of these surface treatments over wear behaviour, impact behaviour, hardness, tensile strength and corrosion behaviour experimentally investigated. Design/methodology/approach: Charpy test, tensile test, hardness measurements, wear tests, salt spray tests conducted over hard chrome plated, nitrided, CrN coated and uncoated X40CrMoV5-1 specimens. Coating thickness and diffusion layers examined by Nikon Eclipse LV150 optical microscope. Findings: Highest micro hardness was observed in CrN coating, which is followed by nitriding and hard chrome plating. In wear tests, highest wear resistance was observed in CrN coating, then nitriding. Hard chrome plated samples were exposed abrasion more than uncoated ones. CrN coating and hard chrome plating didn’t affect the yield and tensile strength of material but increased the modulus of elasticity. It is observed that, nitriding decreased the tensile strength but increased the modulus of elasticity. Decrease in impact energy, and increase in brittleness was observed in descending order of nitriding, CrN coating and hard chrome plating. Research limitations/implications: Tensile test machine with hydraulic jaws can be used in further researches. Practical implications: Suitable surface treatment selection in X40CrMoV5-1 mold steels can be made more accurate by using spider diagrams which found in this research. Originality/value: This study was performed in the frame of the Pamukkale University Scientific Researches Projects Coordination Unit project no 2010FBE036 „Investigation of the Effect of Various Surface Treatments on Properties of Plastic Mold Materials”.
