Alloy steel is a steel made by adding one or more alloying elements (such as Cr, Ni, Mo, etc.) to ordinary carbon steel. Its purpose is to improve the performance of steel. Alloy steel is a very common material for crusher spare parts and crawler chassis parts.
1. High Strength
Alloying elements can significantly improve the tensile strength and yield strength of steel, so that parts can withstand greater loads.
Suitable for：
Crusher parts, such as hammers;
Track shoes;
wheels, sprockets, etc.
2. High Hardness
After heat treatment, alloy steel can achieve higher hardness and improve wear resistance.
Advantage：
Reduce wear;
Extend service life;
3. Good Wear Resistance
This is one of the most important properties of mining machinery.
In high-wear environments such as sand, gravel and ore, alloy steel is more durable than ordinary carbon steel.
4. Good Toughness
Many people mistakenly think that the harder the better, but they are not.
Good alloy steel can take into account：
Sufficient Hardness;
Good Impact Resistance.
This is not easy to break.
5. Good Hardenability
Alloy steel after heat treatment：
Not only is the surface hard，
The interior can also achieve higher hardness.
This is especially needed for large parts.
6. Good Fatigue Strength
Suitable for parts that are repeatedly stressed for a long time.
For example：
Track shoes;
Hammer head;
Link.
It can reduce fatigue cracking.
7. High Temperature Resistance
After adding Cr, Mo, and Ni, it can still maintain good strength in a high temperature environment.
8. Corrosion Resistance
Ordinary alloy steel is not rust-free.
However, after adding a certain proportion of Cr, Mo, and Ni, the corrosion resistance can be improved.
