Why do choose the abrasion resistant steel?

Abrasion resistant steel is a general term for steel materials with high wear resistance. It is also called wear-resistant steel. Abrasion resistant steel is the largest amount of wear-resistant materials available today.

There are also many methods for classification of wear conditions. If divided according to wear mechanism, it can be divided into abrasive wear, adhesive wear, corrosion wear, erosion wear, contact fatigue wear, impact wear, fretting wear and so on.

Performance Properties of abrasion resistant steel
1. Hardness.
Abrasion resistant steel for construction machinery, it is required to have high performance characteristics such as high wear resistance, high toughness, impact resistance, easy welding, and easy forming. The main indicator of wear resistance is surface hardness. The higher the hardness, the better the wear resistance. Compared with NM450 and Q345B, the hardness is only increased by 3 times, but under the same working conditions, the average service life is increased by 6-8 times.
2. Wear resistance test
Compared with the ring block wear test (ASTM G77-05), the wear volume of Q345B is 30 times that of NM400. That is to say, the 30mm thick Q345B steel plate is worn through, and the NM400 is worn away by 1mm. It can be seen that if there is only sliding friction, no impact and other wear, the wear-resistant steel has extremely strong wear resistance.
3. Impact resistance
Since the impact is mentioned, the NM wear-resistant steel plate has good impact toughness, and the ability to resist dents is significantly better than that of ordinary structural steel when subjected to heavy impact. This property is suitable for the production of dump truck compartments and is suitable for thinning of steel plates. According to the comparison and design of different models, the wear-resistant steel is used as the dumping car body, and the car body is reduced by 30-50%.

What is the concept of 30-50% reduction of the car?
According to the data of a certain ordinary dump truck, the use of wear-resistant steel vehicle has reduced 3.215 tons, and the annual driving cost is 20,000 kilometers. The freight can save 3.2 $/km, and the annual freight cost is nearly 1400 $/car. The reason for pulling and running is that the actual benefits are even higher. According to the statistics of the special car association, it can generate more than 4285$ per vehicle per year.
