Hot Work Tool Steel

It is desirable to improve tool steel wear resistance to produce pieces with precise dimensions and increase the lifetime of tools. The aim of this work was to modify the surface of 1.2344 (X40CrMoV5-1) hot work tool steel to improve the wear properties. Surface modification was achieved in three steps: first, hardening was applied, followed by plasma nitridation and, finally, physical vapor deposition (PVD) was employed to produce a TiN/AlTiN multilayer coating. The microhardness and the wear coefficient of the surfaces were measured. PVD coating showed the highest hardness value, 2938 HV0,01, whereas plasma nitridation followed by PVD resulted in 2679 HV0,01. The surface modification resulted in an increase in surface roughness in all cases compared to the hardened sample. However, the wear coefficient showed a significant decrease for the surface treated samples. The lowest wear coefficient of K = 1.47 10–10 mm3/Nm, which is a magnitude lower than the reference hardened sample (K = 6.32 10–9 mm3/Nm), was achieved employing both plasma nitridation and PVD. The results confirm that the use of a combined surface modification of plasma nitridation and PVD significantly improve the wear resistance of the treated samples.

Abstract Crucible CPM Rex 54 HS is a cobalt-bearing high speed tool steel that is produced by the proprietary Crucible Particle Metallurgy (CPM) process. It combines the wear properties of the popular high vanadium M4 grade with the red hardness of the cobalt-bearing M35/Crucible CPM Rex 45 HS grades. Crucible CPM Rex 54 HS may be used as an upgrade for improved red hardness over M3 or M4 without giving up the abrasion resistance, or as an upgrade for improved wear resistance over M35 or Crucible CPM Rex 45 HS without giving up the red hardness. This datasheet provides information on composition, physical properties, microstructure, hardness, and elasticity. It also includes information on wear resistance as well as heat treating and surface treatment. Filing Code: TS-818. Producer or source: Crucible Industries LLC.

Wear Tests

Good mechanical and wear properties of hot-work tool steels are needed for tools to withstand severe service conditions during their operational lifetime. Thus, the aim of this investigation was to correlate mechanical and wear properties with changes in microstructure of commercially available hot work tool steel Sitherm S361R. Hardness, impact toughness, tensile strength and wear tests were performed. Hot-work tool steel was heat treated at austenitizing temperature 1030 °C for 15 min in a horizontal vacuum furnace and gas quenched using nitrogen. One set of samples was investigated in as quenched state. Double tempering of samples was performed after quenching for 2 h at each of chosen temperatures, with first tempering temperature of 500 °C for the whole set of tempered samples. The second tempering was conducted at temperatures from 520 °C to 640 °C with increment of 30 °C for each set of samples. Microstructure of differently heat treated samples showed martensitic matrix, but different fraction and distribution of carbides, consequently influencing hardness, impact toughness, tensile strength, yield strength and wear resistance. Reciprocating sliding wear tests were carried out at room temperature in order to correlate microstructure of differently heat treated hot-work tool steel with wear. In order to achieve adhesive and abrasive wear mechanisms, 100Cr6 and Al2O3 balls were used as counter-body, respectively. Combination of adhesive and abrasive wear was observed for all specimens with different hardness when using 100Cr6 material as a counter body. However, in the case of Al2O3 abrasive wear was found as the prevailing wear mechanism.
