The difference between wear-resistant steel used in mining machinery and engineering machinery

The application of wear-resistant steel NM400 in mining machinery and engineering machinery has the following differences:

1、 Working environment

Mining machinery: harsh environment, high dust, high humidity, strong corrosiveness, narrow working space;

Construction machinery: The environment is diverse and complex, with relatively low humidity and corrosiveness, and the working space is relatively open.

2、 Force characteristics

Mining machinery: high impact force, high wear force, long-term heavy load;

Construction machinery: variable loads, dynamic impacts, and susceptibility to fatigue wear.

3、 Equipment type and components

Mining machinery: components such as crushers, mining equipment, and transportation equipment are severely worn out;

Engineering machinery: Earthmoving machinery, concrete machinery, lifting machinery and other components have relatively light wear.
