Special wear-resistant steel refers to high manganese steel, also known as austenitic manganese steel. It is the primary type of particularly wear-resistant steel, with high toughness and high cold work hardening ability.

It is mainly used for wear-resistant castings under high impact abrasive wear conditions. After water toughening treatment, high manganese steel has high toughness and high cold work hardening ability. Used under high impact loads, it has good wear resistance and is safe and reliable.

Characteristics：

(1) After water toughening treatment, it has excellent toughness and plasticity, which is essential in many mining and crushing equipment that bear large impacts.

(2)strong work hardening ability

Under the working conditions of impact wear, a hardened layer is formed. The larger the impact load, the deeper the surface hardened layer, the higher the hardness ,and the stronger the anti-wear ability. Moreover, it also maintains the high toughness of the engineering component itself, which is not found in general wear-resistant alloy steel and wear-resistant cast iron.

(3)The production process of Austenitic steel is simple

The process properties of the material are excellent and the quality is easy to control. The above characteristics must be considered when selecting Austenitic steel to make work pieces. Under the condition of no impact load, high manganese steel cannot exert its characteristics. Due to its relatively soft austenite matrix, the wear resistance of steel is not as good as that of ordinary cast iron.

In addition, according to the requirements of working conditions, countries have developed and produced modified Austenitic steel, that is, on the basis ofAustenitic steel composition add 1.5% ~ 2.5% chromium, or 3.0% ~ 4.0% nickel, or 0.9% ~ 1.2% molybdenum and Austenitic steel with vanadium and titanium, so that the performance of Austenitic steel has been significantly improved.

Product use：

It is widely used in metallurgical mining machinery, construction machinery, agricultural machinery, electric machinery, railway transportation machinery, building materials and military and other departments.
