Plate Sheet Hot Rolled Wear Resistant Abrasion Resistant Mild Steel NM450.
The weight of NM450, calculated based on a density of 7.85g/cm³:
Costo = (Material unit price × Weight + Processing fee + Loss + Logistics) ÷ Yield rate
Core formula: Weight (kg) = Length (m) × Width (m) × Thickness (mm) × 7.85
Derivation logic: Based on volume × density (7850kg/m³), after unit conversion, it simplifies to the above coefficient.
Calculation example: 16mm thick × 2m wide × 6m long steel plate, weight = 2 × 6 × 16 × 7.85 = 1507.2kg
Secondary processing fee: Approximately 1.5 – 3 yuan/kg.
Loss reserve: Loss is usually ≤ 3%

NM450 alloy steel plate wear resistant steel sheet is more wear-resistant than ordinary steel plates, has a longer service life, higher strength, and requires more precise processing.
Yes, in most wear-resistant conditions, NM450 steel plates and AR450 can be used interchangeably, but not in all cases can they be directly substituted for each other.
6mm-100mm Thickness NM450 Wear Resistant Steel Sheet is a brand name for wear-resistant steel plates in China. It is usually produced in accordance with standards such as GB/T 24186.
Hardox 450 is a brand of steel manufactured by a Swedish steel company.
Both have excellent wear resistance. Due to its brand, Hardox 450 usually has a higher price.
NM450 is from China,
and Raex 450 belongs to SSAB.
In most wear-resistant applications, NM450 Wear Resistance Steel Plate can be used as a performance-similar alternative material to Raex 450.
The NM450 Wear-Resistant Hot Rolled Carbon Steel Plate Sheets has a low procurement cost, fast delivery time, a wider range of specifications, excellent processing performance, and rich export experience.
Hard Plate Wear Plate NM450 Carbon Steel Sheet is suitable for both sliding wear and moderate impact wear, but not for extremely strong impact.
