Wear resistant steel plate is designed to withstand abrasion, impact and wear in many industrial applications. It is used in constructions, mining, earthmoving and manufacturing industries here materials are exposed to extreme wear conditions. These plates provide high durability, extended life, and have a cost effective performance in a harsh environment.
Composition and Manufacturing Process
Wear resistant steel plates are made of high carbon steel combined with elements like chromium, manganese and nickel. The composition of these elements increases the hardness, strength and toughness of making the plates suitable for extreme working conditions.
The manufacturing process includes:
- Melting and Alloying: Raw materials are melted in a furnace and combined with alloying elements to improve mechanical properties.
- Rolling and Heat Treatment: The steel is hot-rolled and subsequently heat-treated, involving quenching and tempering, to obtain the required hardness and strength.
- Surface Hardening: Wear-resistant plates receive further surface treatments to enhance resistance to wear and impact.
Properties of Wear Resistant Steel Plate
- High Hardness: The wear resistant steel plates usually have a hardness between 300 HBW (Brinell Hardness) and more than 600 HBW in order to be resistant to abrasion and impact.
- Good Toughness: Even under extreme hardness these plates retain a sufficient amount of toughness, thereby lessening the chances of cracking at heavy loads.
- Greater Strength: The hardness and strength make these plates perfect for demanding applications.
- Good Formability and Weldability: Higher grades of wear-resistant steel possess great weldability and can be bent into various forms without sacrificing strength.
- Corrosion Resistance: Certain grades contain corrosion-resistant characteristics, increasing longevity in extreme environments.
Types of Wear Resistant Steel Plate
There are a number of wear-resistant steel plates, which are produced for various uses:
- AR (Abrasion Resistant) Steel Plate: Used for general-purpose high-impact and abrasion scenarios, AR plates are found in multiple grades like AR400, AR450 and AR500 which signify their hardness levels.
- Hardox Plate: A high-end wear-resistant steel brand, Hardox is reputed for its exceptional strength, toughness and versatility of application in industries such as mining and construction.
- XAR Plate: Thyssenkrupp produces XAR plates which show superior wear resistance and are often utilized in heavy machinery and equipment.
- Creusabro Plate: High strength steel with improved work hardening property used in applications involving severe wear.
- NM Plate: Commonly used in the Chinese market, NM wear resistant steel offers reliable hardness and toughness for industrial applications.
