High Hardness: 440C stainless steel has the highest carbon content of all stainless steels, which imparts its exceptional hardness. With proper heat treatment, its hardness rivals that of some high-carbon tool steels.

Excellent Wear Resistance: Its high hardness translates directly to excellent wear resistance, meaning 440C maintains a long service life in applications subject to high friction or wear.

Good Corrosion Resistance: Despite its reputation for high hardness, 440C maintains the excellent properties of stainless steel. Its high chromium content (typically 16-18%) provides excellent corrosion resistance in normal atmospheric conditions, fresh water, and certain mild acid and alkaline environments.

Heat Treatable: 440C stainless steel can be modified through heat treatment processes such as quenching and tempering to achieve the desired balance of hardness and toughness.

Due to its superior overall performance, 440C stainless steel is widely used in the following areas:

Knives and Cookware: It is a common material for producing high-quality kitchen knives, outdoor knives, and scalpels, as its high hardness ensures a long-lasting sharp edge.

Bearings: 440C stainless steel is commonly used in the manufacture of precision bearings, rolling element bearings, and ball bearings, particularly where corrosion resistance is required or where operation in humid environments is required.

Molds and Tools: Due to its high wear resistance, it is also commonly used in the manufacture of plastic molds, measuring tools, and cutting tools, where wear resistance is critical.

Other High-Demand Components: Valves, nozzles, pump parts, and other mechanical components requiring high hardness and a certain degree of corrosion resistance.
