Mechnical property for NM450 Abrasion resistance steel plate:

 Advantages of NM450 Wear-Resistant Steel：

Brinell hardness ranges from 420 to 480 HBW. Its abrasion resistance is 2 to 3 times better than Q345 steel, and its wear loss is merely 1/5 to 1/3 of conventional carbon steel plates.These superior mechanical properties make it ideal for vibrating screens, material handling and other heavy-duty equipment.

 Advantages of curved structure:

• Stress dispersion: Curved design distributes concentrated impact evenly into compressive stress. It offers 30%–50% higher deformation resistance than flat plates and avoids bulging & cracking.

• Smooth material flow: Perfectly fits material sliding routes on hoppers, chutes and screen decks, reducing jamming, material buildup, flow resistance and wear.

• Higher rigidity: Curved plates feature better flexural stiffness at equal thickness. We can use thinner plates (6mm replacing 8mm) to reduce weight while retaining full strength.

 Economic advantages：

• Longer service life: Excellent wear & impact resistance extends maintenance cycles 3–5 times and cuts downtime losses effectively.

• Cost-effective solution: Lower total life-cycle cost. Though priced higher than regular steel plates, it provides superior overall value.

01

Excavator and loader Components

• Bucket Liners & Curved Side Liners：The curved inner sections and bottom arcs of buckets endure constant impact from soil, rock and ore. The perforated structure cuts down overall weight while delivering reliable wear protection and longer bucket service life.

 

• Curved Bucket Guide Plates：Fitted at the bucket discharge opening, these curved guide sections eliminate material blockage and adhesion, ensuring steady and smooth material discharge.

02

Screening And Conveying Engineering Machinery

• Arc Screen Deck / Curved Screen Plate: Its curved profile matches the rolling path of bulk materials. The perforated design enables effective screening and classification. This plate features excellent wear resistance and anti-scouring performance, with high rigidity to prevent deformation and material clogging.

 

• Curved Liner for Chutes & Feeders：Chutes used for feeding, transfer and discharge suffer severe abrasion from high-speed sliding bulk materials. This curved wear liner delivers outstanding wear resistance and self-cleaning properties, greatly lowering maintenance and cleaning work.

03

Crushing / Mining Machinery

• Feed Hopper Curved Liner & Receiver Curved Plate：Endures impact and friction from lump ore. High hardness combats gouging wear, and the curved design cushions heavy impacts.

 

• Discharge guide arc plate: The area for guiding material after crushing, wear-resistant and erosion-resistant, preventing rapid wear through the plate.

04

Paving / Earthmoving Machinery

Arc-shaped inner lining of the silo: The arc-shaped sidewall of the storage silo prevents material sticking and provides wear resistance during long-term friction between sand, gravel, and mixed materials.

 

Arc-shaped baffle of the discharge hopper: The arc-shaped structure of the discharge port guides material flow and reduces localized concentrated wear.

 Plate Thickness (Mainstream Selections)

• Protective Plates, Lightweight Liners: 4mm, 5mm, 6mm
• General Purpose Liners, Deflectors: 6mm, 8mm
• Heavy-Duty Impact Zone, Bucket Body Liners: 8mm, 10mm, 12mm

 Hole type selection

• Round Holes: General purpose, low cost, good flowability, the first choice for most working conditions.
• Slotted Hole: Specifically for screening and chute applications, with better anti-clogging effect.

 Aperture matching materials

• Fine materials/powder: φ6~φ12mm
• Conventional sand and gravel: φ12~φ20mm
• Large materials/anti-clogging requirements: φ20~φ30mm

 Arc parameters

• Curvature/Radius: Strictly customized according to the curvature of the original equipment parts and installation space, divided into large arc, small arc, and semi-circular arc.
• Arc Length/Unfolded Dimensions: Actual measured length and width of the installation position, distinguishing between full arc panels and segmented spliced ​​arc panels (segmented models are used for large-size cavities).

• High-grade NM450 wear-resistant steelHardness 420–480 HBW, high strength and great impact resistance. Resists cracking even at low temperatures and stands up to heavy-duty abrasion.

• Functional structural designCurved shape absorbs impacts and avoids bulging; standard perforations ensure smooth material flow and effective screening. Anti-clogging and anti-deformation performance is outstanding.

• Fine processing qualityAccurate bending and perforation, stable dimensions for easy installation and seamless matching with your equipment.

• Long service life & less maintenanceWith excellent wear resistance, it extends service intervals and reduces downtime caused by frequent part changes.

• Cost-effective solutionLower total life-cycle cost and higher comprehensive value compared with conventional steel products.

• Flexible customizationAvailable in various thicknesses, hole specifications and curvatures to meet your personalized demands.

FAQ:

What is the difference between NM450 and Hardox 450?

NM450: NM450 is a wear-resistant steel grade produced by a variety of manufacturers. It does not have a specific brand name associated with it. Hardox 450: Hardox 450 is a brand of abrasion-resistant steel manufactured by SSAB, a Swedish steel company. Hardox is a well-known and widely used brand in the industry.

Can NM450 be used in high-heat environments?

NM450 is not designed for high-temperature service. If the operating temperature exceeds 250°C (480°F), the material will undergo tempering, leading to a significant drop in hardness and wear resistance. For high-temp applications, specialty "Heat Resistant" grades or cladding are required.
