Introduction
Abrasion steel plate is made of alloy components rich in chromium and carbon, with a Brinell hardness of up to 600 HB (≥570 HB). It is a high-strength, high-hardness wear-resistant steel plate. It can be used in mining, construction, cement, material handling and other industries, as crushers, hoppers, chutes, liners and other high-wear parts.
Advanatges
Long service life
Brinell hardness ≥570 HB, hardness value up to 600 HB, yield strength usually exceeds 1100 MPa. NM600 steel plate can withstand heavy impact and strong friction, and its service life can be 4 to 5 times longer than traditional steel. It reduces the maintenance cost of equipment and machinery, and is particularly suitable for applications with severe wear.
Corrosion resistance
Abrasion steel plate contains 1.5% to 2% chromium, which is an element that can enhance the corrosion resistance of steel. Chromium can form a dense oxide film on the surface of steel, which can effectively prevent the intrusion of oxygen and moisture, thereby reducing the corrosion reaction of the steel plate.
Applications
Mining and mining industry
Used in the manufacture of mining machinery and equipment, such as crushers, screens, chutes, hoppers and other parts.
Construction and civil engineering
Used in the manufacture of concrete mixers, bulldozers, shovels, excavators and other equipment.
Cement industry
Applied in wear-resistant parts of cement plant equipment, such as crusher liners, conveyor belts, mill liners, etc.
Material handling
Used in material handling systems such as hoppers, conveyors, and unloading devices.
Agriculture
Used in parts of agricultural equipment such as tractors, harvesters, and tillage machinery.
Steel and metallurgical industry
Used in wear-resistant liners, grates, roller liners of steel plate rolling mills and other parts of smelting furnaces.
Forestry and papermaking industry
Used in wear-resistant parts of papermaking equipment, such as pulp mixers, conveying systems of papermaking machines, and wood processing equipment.
Construction equipment
Such as excavator buckets, drill bits, and scrapers.
FAQ
Q: What is the difference between abrasion steel plate and HARDOX 600 steel plate?
A: abrasion steel plate and HARDOX 600 steel plates have similar hardness and wear resistance, but they differ in alloy composition and processing methods. HARDOX 600 may have advantages in impact resistance and toughness, while abrasion steel plate may be more competitive in price and processability.
Q: Is NM600 abrasion steel plate easy to weld?
A: abrasion steel plate has good weldability, but due to its high hardness, appropriate welding process and welding materials need to be used during welding to avoid thermal cracks.
Q: Will abrasion steel plate crack during use?
A: Although abrasion steel plate has excellent wear resistance, it may still crack when subjected to high impact or extreme load. Therefore, overload operation should be avoided in design and use, and reasonable maintenance should be ensured.
Q: Is abrasion steel plate suitable for equipment in cement plants?
A: abrasion steel plate wear-resistant steel plates are very suitable for cement plant equipment such as crushers, mill liners and conveying systems, and can effectively resist the wear and tear in cement production.
Q: How much longer can abrasion steel plate last than ordinary steel?
A: The service life of abrasion steel plate is usually 4 to 5 times longer than ordinary steel, especially in high wear and high impact environments, which can greatly reduce the maintenance and replacement frequency of equipment.
Q: How is the processing performance of abrasion steel plates?
A: Despite its high hardness, abrasion steel plate has good processing performance and can be used for secondary processing such as cutting, drilling and welding. For extra-thick plates, it is recommended to use appropriate tools and equipment to ensure processing accuracy.
Q: Can abrasion steel plates be used in agricultural machinery?
A: Yes, abrasion steel plates are suitable for agricultural machinery, especially for parts that need to withstand heavy loads and high wear, such as tractor buckets, harvester blades, etc.
Q: How to choose the right thickness of abrasion steel plates?
A: The thickness of abrasion steel plates should be selected according to the degree of wear and load in the specific application. For example, thinner plates can be used for the lining of material handling equipment, while thicker plates are required for high-impact components such as crusher linings.
Q: What special precautions should be taken when installing abrasion steel plates?
A: When installing abrasion steel plates, ensure that the connection with other components is firm to avoid uneven wear or impact on the plate due to improper installation. In addition, regular inspections and maintenance should be performed to extend its service life.
Q: What precautions should be taken when transporting NM600abrasion steel plate?
A: During transportation, abrasion steel plates should avoid direct contact with sharp objects to prevent surface damage. At the same time, keep the plates dry and avoid exposure to humid environments to prevent surface corrosion.
Q: How to clean and maintain abrasion steel plates?
A: In order to maintain the good performance of abrasion steel plates, regularly remove debris and wear materials accumulated on the surface, and avoid long-term exposure to humid and corrosive environments. For long-term exposed parts, consider applying anti-corrosion coatings to further improve their corrosion resistance.
Q: What are the quality control standards for NM600 abrasion steel plate?
A: The quality control standards for abrasion steel plates include hardness testing, chemical composition analysis, surface quality inspection, etc. Products generally comply with international standards and are certified by ISO, EN, etc., ensuring their reliability in different applications.
