The main feature of abrasion resistant plate is its high wear resistance. Its wear resistance is 30 times that of ordinary low-alloy steel plate. abrasion resistant plate has high strength, low alloy content, easy welding and processing. It is mainly used as a lining plate in the friction parts of mechanical equipment, which greatly improves the service life of the equipment, ensures the normal operation of the equipment, and reduces the losses caused by maintenance and downtime. The delivery status of abrasion resistant plate is generally divided into tempered state and quenched and tempered state (quenching + tempering). Relatively speaking, the quality of quenching + tempering is better!
What are NM400/NM500 wear-resistant steel plates?
NM series steel plates are the abbreviation for "wear-resistant" steel plates (NM = wear-resistant). The number represents the Brinell hardness (HB):
• NM400: Hardness approximately 400 HB
• NM500: Hardness approximately 500 HB
Their key features are: high hardness + good toughness + excellent impact resistance + good machinability.
What are the application differences between 6mm, 8mm, and 10mm thicknesses?
Let's look at three common thicknesses for practical applications to help you quickly find the right size for your needs:
6mm Thick NM400/NM500
Suitable for:
• Conveyor Chute Liners
• Construction Waste Treatment Equipment Guards
• Small Concrete Mixing Plant Blades
Advantages:
• Lightweight, easy to weld and install
• Replaces Q345 and Q235 sheet materials, increasing service life by over three times
8mm Thick NM400/NM500
Suitable for:
• Construction Machinery Hopper Floors
• Mixing Plant Liners
• Crushing and Screening Equipment Components
Advantages:
• Excellent balance between wear resistance and structural strength
• The most widely used intermediate thickness in the market
10mm Thick NM400/NM500
Suitable for:
• Liners for Large Mining Equipment
• Bulldozer Blades
• Large Slag Conveying Equipment
Advantages:
• Greater impact resistance, suitable for harsh operating environments
• Multiple weld repairs extend the service life.
Why is it worth a try for those who haven't used wear-resistant plates?
If you've previously used ordinary steel plates, you may have encountered the following issues:
• Easy wear and short service life
• Frequent replacements and high downtime costs
• High total costs
