NM400 NM500 Wear Resistant Perforated Plate
Perforated plates are widely used in high-load screening environments such as mining, aggregate processing, and mineral separation, serving as heavy-duty screens. Our perforated plates are made of NM400/NM500 grade high-strength wear-resistant steel and manufactured through precision stamping processes, ensuring long service life, high screening efficiency, and good structural stability.
NM400/NM500 Perforated Plate Parameters
Based on industrial perforated plate standards and screening industry requirements:
Plate Thickness: Typically up to about 12.5 mm for industrial screening plates
Hole Size Range: Approx. 3mm – 10 mm or larger depending on application
Hole Types: Round, square, rectangular, slotted, hexagonal
Plate Form: Flat plate or rolled sheet
Manufacturing Standard: ISO-based hole tolerance and pitch control
Industrial perforated plates are designed so plate thickness is normally lower than hole diameter to maintain strength and screening efficiency.
Perforated metal screens can be manufactured with multiple hole patterns and surface coatings, supporting customized design for different industries.
Various Hole Styles
Main characteristics and functions of NM400 and NM500 perforated plates
Wear-resistant perforated plate screens are screens with uniformly sized holes formed on a wear-resistant plate through a mechanical stamping process, exhibiting excellent wear resistance and impact resistance.
The perforated plate screen has uniform mesh precision, is not easily deformed, and is suitable for screening large particles.
Perforated plate screens offer a variety of mesh shapes, such as rectangular, square, rhomboid, circular, hexagonal, rectangular, and irregular shapes, to meet diverse screening requirements.
Perforated plate screens are not only used in mining but also as wear-resistant components in key processes such as material classification, screening, and dewatering in the metallurgical and building materials industries.
Advantages of NM400/NM500 perforated screen
High Load Capacity
The robust and durable screen structure allows perforated plates to handle high-tonnage materials and perform continuous screening operations.
Excellent Abrasion Resistance
NM400/NM500 wear-resistant steel plates have excellent wear resistance and impact resistance. Wear-resistant screen plates made from these steel plates have extremely high wear resistance, which can reduce replacement frequency and maintenance costs.
Stable Screening Efficiency
Uniform aperture and precise aperture spacing ensure consistent particle separation and high throughput.
Anti-clogging Performance
The optimized aperture layout design improves material flow and reduces clogging during the screening process.
Long Service Life
Compared to traditional screens, perforated screens have a longer service life under abrasive conditions.

FAQ：
What is a perforated plate?
Perforated plate is manufactured by cold punching sheets of metal with an arrangement of holes of any shape and size in various patterns. There is a large variety and we only stock the more popular specifica- tions although others are available to special order.
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.
What are the properties of NM500 material?
Some key properties of NM500 steel include: Hardness: Typically, NM500 steel has a hardness range of 470-550 HBW (Brinell Hardness), indicating its exceptional resistance to abrasion and wear. Strength: NM500 steel offers high strength, enabling it to withstand impacts and abrasive forces in harsh operating conditions.
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.
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.
