Wear Resistant Steel Plate NM400 NM450 NM500 Hot Rolled Plate

As ideal core materials for dealing with high-wear conditions, our hot-rolled wear-resistant steel plates-NM400, NM450, and NM500-have all undergone rigorous heat treatment processes, possessing excellent surface hardness, impact resistance, and superior machinability.

• NM400: Combining good toughness with high hardness, it is suitable for medium-wear environments and is a cost-effective choice for structural components and liners.
• NM450: Further increased hardness, achieving a balance between resistance to sliding wear and impact wear, widely used in mining and construction machinery.
• NM500: An ultra-high hardness level, specifically designed for extreme working conditions with strong abrasion and high impact, significantly extending component lifespan.

NM500 steel plate 

Customizable cutting, leveling, bending, and laser cutting services.

Surface finish: Smooth, crack-free, and with precise tolerances.

The production of NM400/NM450/NM500 hot-rolled wear-resistant steel plates strictly adheres to high-end standards. High-quality low-alloy steel billets are selected, and wear-resistant alloy elements are precisely proportioned and heated in stages with controlled temperature. After high-pressure water descaling, multi-pass precision hot rolling, and laminar flow controlled cooling, a "quenching + high-temperature tempering" tempering process ensures that different grades achieve their corresponding hardness standards. Finally, finishing, leveling, and comprehensive testing are performed. The entire process is intelligently managed and traceable, guaranteeing high wear resistance, high toughness, and good machinability, making the products suitable for various heavy wear conditions.

FAQ:

1.What is NM400 steel?

NM400: A Chinese-standard wear-resistant steel (NM stands for "Nai Mo," meaning wear-resistant in Chinese), NM400 typically has a Brinell hardness (HBW) of 360–440. It's known for its balance of hardness, toughness, and cost-effectiveness, making it popular in Asia and beyond.

2.Is steel plate hot rolled?

Mild Steel Plate Hot Rolled Plate is a flat shaped plate of hot rolled mild steel. The hot-rolled finish produces a smooth surface, while the mild steel composition allows easy welding, cutting, and machining.

3.What is NM450 steel?

NM450 is a type of abrasion-resistant steel plate known for its exceptional hardness and strength. With a Brinell hardness value of around 450 HBW, NM450 abrasion-resistant plates are engineered to withstand severe wear while maintaining structural integrity.

4.What is the difference between AR500 and NM500?

AR500: Higher carbon (C: ~0.38–0.45%), chromium (Cr: ~1.5%), and boron (B: 0.0005–0.006%) for enhanced hardness and corrosion resistance . NM500: Lower carbon (C: ≤0.38%), added nickel (Ni: ≤1.0%) and molybdenum (Mo: ≤0.65%) for balanced weldability and toughness .

5.What is the difference between Hardox 500 and NM500?

Hardness: NM500 typically has a hardness range of around 470-540 HBW (Brinell hardness), while Hardox 500 typically falls within the range of 470-530 HBW. The hardness level indicates their ability to withstand abrasive wear and impact.
