NM400 Wear Resistant Steel Plate 10mm 15mm 20mm for Mining Machinery and Heavy

The NM400 wear resistant steel plate is a high-hardness structural steel plate designed for severe abrasion and impact conditions. Manufactured by Sylaith in Jiangsu, China, this hot-rolled carbon steel sheet delivers excellent wear resistance while maintaining good weldability and formability. With thickness options of 10mm, 15mm, and 20mm, it is ideal for mining machinery, heavy industry equipment, and building material applications. The NM400 grade meets multiple international standards including AiSi, ASTM, DIN, BS, GB, and JIS, with a tight ±1% thickness tolerance.

Mining and heavy industry equipment face continuous high-impact and high-abrasion environments. Ordinary carbon steel plates wear out quickly, leading to:

• Frequent equipment downtime for part replacement
• Increased maintenance costs
• Reduced operational efficiency
• Shortened service life of critical components
• Higher total cost of ownership

Standard steel plates lack the hardness and toughness required for extreme conditions such as ore handling, earthmoving, and material processing.

The NM400 wear resistant steel plate solves these problems through:

• High surface hardness (360–440 HBW) for excellent abrasion resistance
• Good impact toughness to withstand heavy loading without cracking
• Hot-rolled process ensuring uniform mechanical properties
• ±1% thickness tolerance for consistent performance
• Coated surface treatment for added corrosion protection
• Available processing services – bending, welding, cutting, and punching
• Fast 7-day delivery for standard thicknesses

This combination significantly extends equipment life and reduces maintenance frequency, lowering overall operating costs.

The NM400 wear resistant steel plate is widely used in:

• Excavator buckets and teeth
• Dump truck liners
• Crusher components
• Conveyor chutes and hoppers
• Screening equipment

• Loader buckets
• Bulldozer blades
• Grader blades
• Concrete mixer drums
• Industrial shredders

• Structural supports
• Foundation plates
• Wear-resistant liners for silos and bins
• Formwork and temporary structures

• Heavy-duty cutting tools
• Wear plates for material handling
• Industrial machine frames

The NM400 wear resistant steel plate is produced through a specialized hot-rolled and heat treatment process:

High-quality carbon steel billets with optimized chemical composition (including carbon, manganese, chromium, and boron) are selected to achieve the required hardness and toughness.

The steel billets are heated to approximately 1100°C–1200°C in a reheating furnace, making the material plastic and ready for rolling.

The heated steel passes through multiple rolling stands to achieve the target thickness (10mm, 15mm, or 20mm). This process refines the grain structure and ensures uniform thickness with ±1% tolerance.

The rolled plates are rapidly cooled (quenched) to transform the microstructure into martensite, achieving high hardness of 360–440 HBW while maintaining core toughness.

Depending on application requirements, the plates may undergo tempering to balance hardness and impact resistance.

The plates are leveled to ensure flatness, then cut to customer-specified lengths (1–12m).

A protective coating is applied to prevent rust and corrosion during storage and transport.

Every plate undergoes:

• Hardness testing (HBW)
• Dimensional inspection (±1% tolerance)
• Surface quality assessment
• Mechanical property verification (tensile strength, yield strength)

Custom processing services include bending, welding, cutting, and punching per customer requirements.

Selecting the right wear resistant steel plate depends on your specific application:

A: NM400 is a specialized wear resistant steel with hardness of 360–440 HBW, significantly higher than ordinary carbon steel (120–180 HBW). This makes NM400 last 3–5 times longer in high-abrasion environments, reducing replacement frequency and downtime.

A: Yes. NM400 maintains good weldability and formability. Standard welding procedures (low-hydrogen electrodes, preheating when necessary) should be followed. Bending is possible but requires adequate bending radius to avoid cracking due to high hardness.

A: Standard MOQ is 1 tons. Delivery time is 7 days for standard thicknesses (10mm, 15mm, 20mm) without custom processing. Custom sizes or processing may require additional lead time.

A: Yes, MTC is available upon request, including chemical composition, mechanical properties, heat number, and batch traceability.

A: We accept 30% T/T advance + 70% balance before loading. Other terms (L/C, T/T) negotiable based on order quantity and customer relationship.
