Abrasion-resistant steels, also known as wear-resistant steels, are a highly sought-after type of steel due to their superior durability and strength. These steels are designed to withstand harsh conditions and resist wear and tear from constant use, making them ideal for various industrial applications. Regular steels can quickly degrade and fail when exposed to abrasive materials or high-impact forces, leading to costly downtime and repairs. On the other hand, Abrasion-resistant steels can significantly extend the life of machinery and equipment, reducing overall maintenance costs and improving productivity. From mining trucks to bulldozers, these steels are a game-changer for those in demanding industries looking for dependable, long-lasting solutions.
Abrasion resistant steels are made from iron, carbon and other alloying elements. Abrasion resistant steel is developed specifically for services in harsh conditions. These product are chosen for their long service life and relatively less weight. Abrasion resistant steels have higher amounts of carbon and other alloying elements such as chromium. Resistance to Abrasion is developed when it undergoes heat treatment. The strong resistance to abrasion helps the steel work effectively in demanding applications such as mining, conveyors, construction and earth moving. Abrasion resistant steel is available commercially in grades like AR200, AR235, AR400, AR400F, AR450, AR450F, AR500, AR500F and AR600.
Properties of Abrasion-resistant steels
- Abrasion-resistant steels are designed to resist high levels of wear and tear.
- These steels typically have a high hardness level, making them difficult to machine and weld.
- Abrasion-resistant steels can be divided into two main categories: martensitic and austenitic.
- Martensitic steels are the most common type of abrasion-resistant steel. Their high hardness and strength characterize them.
- Austenitic steels are less common than martensitic steels, but they offer superior resistance to corrosion and heat.
- Abrasion-resistant steels are used in various applications, including construction, mining, and manufacturing.
- Abrasion-resistant steels can be expensive, so selecting the right grade for the intended application is essential.
- Abrasion-resistant steels are an essential part of many industries and will continue to be so in the future.
Uses of Abrasion-resistant steels
AR200 and AR 235 are used for structural applications, as they provide better strength when compared to other structural steels. AR medium steels are used for moderate level operations. AR400 is known for its strength, whereas AR450 is used for applications that require higher strength in comparison. AR500 is used for applications in truck-trailer industry, mining industry and concrete industry. It has high resistance to impact stress even at low temperatures. It is popularly used for preparing body armour and ballistic plates. AR600 is used for applications that require high strength. Applications using impact or sliding contact with abrasive materials make use of Abrasion resistant steel.
Abrasion-resistant steels FAQs
