Manganese steel is a low-strength, high-ductility material. But properly controlled heat treating by austenizing and followed by water quenching or controlled air cooling, the 12% manganese steel, ASTM 128 A, consists of a meta-stable austenitic phase having a face centred cubic (fcc) latt with strengthening from interstitial carbon and substitutional manganese atoms. Another property of

Tempering is a heat treatment that is only relevant to steels and is carried out to soften any hard micro-structures that may have formed during previous heat treatments, improving ductility and toughness. Tempering also enables precipitates to form and for the size of these to be controlled to provide the required mechanical properties. This

Unlike ordinary carbon steel, high manganese steel after quenching in the water is not hardened, but become soft, so high manganese steel heat treatment is also called water toughness treatment. In the heat treatment process, the carbide is dissolved in the solid state to the austenite to go, so called solid solution strengthening treatment

Heat treating - Wikipedia Heat treating - Wikipedia

Heat treatment of steels is the heating and cooling of metals to change their physical and mechanical properties, without letting it change its shape. Heat treatment could be said to be a method for strengthening materials but could also be used to alter some mechanical properties such as improving formability, machining, etc.

The steels shown in blue can be heat treated to harden them by quenching. Hardening Temperatures. The temperatures for hardening depend on the carbon content. Plain carbon steels below 0.4% will not harden by heat treatment. The temperature decreases from approx 820 C to 780 C as carbon content increases from 0.4% up to 0.8 %.
