In this context, it can be stated that the harder the steel, the greater its wear resistance. Changing the hardness of the surface area (by way of nitriding, coatings, surface hardness, for example) increases wear resistance. Wear resistance is highly dependent on the carbon content of the steel.

Nitriding for Corrosion and Wear Fatigue Resistance
The methods that are used in surface engineering to control wear and fatigue fractures are divided into two types: 1. Coating Application This involves applying high-performance coatings to the surface of the material. In some cases, very hard coatings such as chromium, titanium carbides or titanium nitrides are applied to the surface. (Discussed in the article Erosion Corrosion: Coatings and Other Preventive Measures.) These coatings usually have good corrosion resistance and high wear resistance. HoweverSee more on corrosionpedia die steel px88 steel Surface treatmentInvestigation of Surface Hardness of Steels in Cyanide die steel px88 steel Surface treatmentsurface is developed by heating the steel above the austenitizing temperature in a suitable bath of cyanide salt while the carbon and nitrogen diffuse into the steel surface.

How is precision Punch and tooling steel treated?
This steel develops high hardness and has exceptional resistance wear and abrasion. Standard, Special and Custom Tooling manufactured by Precision Punch & Tooling Corporation are heat treated primarily using Salt Bath processes that are superior to heat treatment using Vacuum and Controlled Atmosphere Furnace processes.See all results for this questionHow are hot work die steels tempered after hardening?Hot work die steels are usually subjected to a heat treatment cycle prior to use (Figure 1). After hardening (by quenching) they are also usually tempered (once or multiple times) to provide enough toughness. Tempering temperature is the temperature at which the dies are held after hardening.See all results for this questionHow are die materials used in precision forging?The selection of the die material, hardness and coating is critical for increasing die life in precision forging.
