Supplying Gost Kh12 Steel Featuring Extremely High Wear Resistance - China

GOST KH12 steel is a high-carbon, high-chromium cold-work tool steel adhering to Russian (formerly Soviet) standards.

Classified as a ledeburitic steel, its primary characteristic is exceptional wear resistance.

It corresponds to the Chinese standard Cr12, the US standard AISI D3, and the German standard 1.2080 (X210Cr12).

**Wear Resistance Mechanism**

**Abundant Eutectic Carbides: ** The high carbon and chromium content results in the formation of a large volume of coarse, continuous, and reticular (Fe, Cr)₇C₃-type carbides in the as-cast or annealed state.

With a hardness reaching HV 1200–1500, these carbides serve as the structural backbone for resisting abrasive wear.

**High Matrix Hardness: ** Following quenching and low-temperature tempering, the hardness of the steel matrix can reach HRC 60–64; this hard matrix supports the carbide network and prevents it from spalling or detaching.

**High Stability: ** The carbides exhibit strong stability, resisting decomposition or softening even under conditions of high temperature and high stress.

This ensures dimensional stability and a long service life in wear-intensive applications.

**Typical Applications of GOST KH12 Steel (Emphasizing High Wear Resistance)**

Specifically designed for cold-work applications characterized primarily by abrasive wear, rather than severe impact:

Cold blanking dies and trimming dies (for thick plates and hard materials)

Thread rolling dies, thread rolling plates, and wire drawing dies (for applications involving prolonged friction against wire and rod stock)

Cold heading dies and cold extrusion dies (forming tools)

Gauges, measuring instruments, and rolling mill rolls (high-precision, wear-resistant components)

Wear-resistant mechanical parts (bearings, guide rails, cutting tools) Songshun specialized in Special Steel for almost 20 years.

We can supply mold steel, high speed steel, alloy steel, free cutting steel and etc.
