Abrasion-resistance

1) HARDOX abrasion-resistant steel
2) Rubber/manganese steel
3) Abrasion-resistant cast metal
4) Ceramics

Equipment used in quarries, gravel pits, sand pits, clay pits, cement works, construction sites and engineering works, exposed to severe conditions of various types of abrasion, impact and erosive wear and tear combined with large deformations, requires materials of different composition and different properties.

1. Abrasion plate made of HARDOX steel can withstand most types of wear and tear. When manipulating minerals, the wear and tear is seldom of a purely abrasive or impact character. It is usually a combination of both.
   The HARDOX abrasion plate of hardness between 400 and 600 Brinell can withstand severe wear and tear and is used in applications subjected to combined wear and tear.
   
   
2. Rubber is an excellent energy-absorbing material, and similarly as manganese steel is at its best when the impact is perpendicular to the surface.
   
   
3. Cast abrasion plates made for instance of Nihard can withstand a certain number of impacts and due to their high hardness can withstand wear and tear by friction. Their disadvantage is brittleness and long delivery time.
   
   
4. Ceramics are unsuitable for wear and tear by impacts, but are highly resistant against abrasion when exposed to pure friction.
