Wear-resistant steel type wear-resistant steel use method

Wear-resistant steel is widely used in machinery manufacturing, mainly in the selection of mechanical parts materials, balls of steel mills, liners, bucket teeth of excavators, buckets, rolling walls, tooth plates, and hammerheads of various crushers. , track shoes for tractors and tanks, blow plates for fan mills, railroad frogs, middle slot middle plates for coal mine scraper conveyors, kerbs, ring chains, bulldozer blades, shovel teeth, large electric wheel cars Bucket linings, oil and open-cut iron ore punch bits, etc. The following small series for everyone to introduce the types of wear-resistant steel and wear-resistant steel use.

Wear-resistant steel types

1, high manganese steel

The as-cast microstructure of high-manganese steel is usually composed of austenite, carbide and pearlite, and sometimes contains a small amount of phosphorus eutectic. When the amount of carbides is large, it often appears as a network on the grain boundary. Therefore, the as-cast microstructure of high-manganese steel is brittle and unusable, requiring solution treatment. The commonly used heat treatment method is solution treatment, that is, the steel is heated to 1050 to 1100 DEG C., the heat is removed to eliminate the as-cast microstructure, a single-phase austenite structure is obtained, and then the water is quenched to maintain the structure at normal temperature. After heat treatment, the strength, plasticity and toughness of the steel are greatly improved.

2, medium and low alloy wear-resistant steel

This type of steel has a high hardness (Brinell hardness up to HB500) and is weldable. Rolling methods are commonly used to make such steel steel or steel and then welded into components. Low-alloy steel used under conditions of wear as the primary failure mode. It is mainly divided into low-alloy welding wear-resistant steel, low-alloy wear-resistant steel for construction machinery parts, and low-alloy wear-resistant steel for agricultural machinery.

3, chromium molybdenum silicon manganese steel

Silicon-manganese alloy is an alloy composed of manganese, silicon, iron, and a small amount of carbon and other elements. It is a ferroalloy with a wide range of uses and large output. Silicon-manganese alloy is a compound deoxidizer commonly used for steelmaking, and it is a reducing agent for production of manganese metal by production of low-carbon ferromanganese and electric silicon thermal methods. Silicon-manganese alloys can be smelted in continuous operation in large, medium and small submerged arc furnaces.

4, special wear-resistant steel

The type of steel used under specific conditions such as impact wear, corrosion wear, high temperature erosion wear, etc.
