Материал Х120мн12

Х120Мн12 is a high manganese austenitic steel widely used as a wear-resistant material. In addition to X120Mn12, there are several commonly used steel grades designed for high-impact and abrasion-resistant applications. These grades differ mainly in содержание марганца, содержание углерода, and hardness, allowing engineers to select the most suitable material for a specific environment.

Common Wear-Resistant Steel Grades

1. Высокие марганцевые стали

These steels are fully austenitic and known for work-hardening under impact. Примеры включают в себя:

• Х120Мн12 / 1.3401: European DIN grade with 11–14% Mn, 1.1–1.4% C.

• Мн13: Chinese GB grade similar to X120Mn12, widely used in mining and crusher applications.

• Хэдфилд Стил: Classic manganese steel with similar composition, renowned for impact and abrasion resistance.

Приложения: Вкладыши дробилки, футеровки мельниц, вкладыши ковша, ударные молотки.

2. Medium Manganese and Medium Carbon Wear Steels

• Х100Мн12 / Мн12: Slightly lower carbon content, умеренная закалка, used where extreme hardness is not required.

• Х120Мн13: Higher manganese for better austenite stabilization and wear performance.

Приложения: Конвейерные вкладыши, водопад, бункеры, and moderately abrasive environments.

3. Low-Alloy Wear-Resistant Steels

These steels combine high hardness with toughness, usually through quenching and tempering. Common examples:

• АР400 / АР500 (Устойчивая к истиранию сталь): Used in heavy wear applications where high hardness is required from the start.

• НМ360 / НМ400: Non-magnetic or low-magnetic wear-resistant steels with balanced toughness.

Приложения: Горнодобывающее оборудование, earth-moving machines, носить тарелки.

4. Specialized High Hardness Steels

• Hardox 400 / 500: Quenched and tempered steels with high hardness for extreme abrasion resistance.

• НМ600 / NM700: Used in high-impact, high-abrasion environments such as cement, quarry, и тяжелая техника.
