NM400 High Strength Wear-resistant Steel Plate - Excellent Wear-resistant, Long-lasting Guard (Conforms to GB/T 24186 Standard)
Product Overview
NM400 is a kind of high-strength wear-resistant steel plate produced in strict accordance with GB/T 24186-2009 standard, which is specially designed for severe wear environments in heavy industry. "NM" stands for "wear-resistant", and "400" refers to the average value of its Brinell hardness. This product uses an advanced quenching and tempering process (tempering treatment) to ensure high hardness and excellent wear resistance, as well as good toughness and machinability, making it an ideal alternative to ordinary steel to improve equipment life and efficiency.
Core features and advantages
Excellent wear resistance: High hardness guarantees effective resistance to wear caused by material scouring, scraping and impact.
Extended service life: Compared with ordinary structural steel, the wear resistance of NM400 can be increased several times, which significantly extends the service life of equipment components and reduces the frequency of downtime replacement.
Excellent comprehensive mechanical properties: good impact toughness, can withstand a certain impact load, to avoid brittle fracture in violent collision, safe and reliable.
Good processing and welding: steel plate can be cut, bent, punched, drilled and other mechanical processing.
Stable welding performance: With suitable low hydrogen welding consumables and preheating process, NM400 can obtain reliable welded joints, which is convenient for customers to manufacture and repair equipment.
Typical application areas
NM400 wear-resistant steel is the ideal material choice for key equipment in the following industries:
Construction machinery: excavator, loader bucket, knife plate, bulldozer blade, excavator bucket teeth.
Mining machinery: mining dump truck compartment floor, liner, crusher liner, chute, hopper.
Material conveying equipment: screw conveyor blade, drop chute liner, vibrating feeder.
Construction and metallurgical equipment: cement mixer blades, dust removal pipes, steel mill equipment.
Others: agricultural machinery, sanitation vehicles and other wear parts.
