NM500 steel is a type of abrasion-resistant steel similar to AR500, but it is produced according to Chinese standards. Here are the typical specifications for NM500 steel:
Chemical Composition:
Carbon (C): 0.38-0.45%
Silicon (Si): 0.20-0.60%
Manganese (Mn): 1.00-1.70%
Phosphorus (P): ≤0.025%
Sulfur (S): ≤0.010%
Chromium (Cr): 0.70-1.20%
Nickel (Ni): ≤0.65%
Molybdenum (Mo): ≤0.25%
Mechanical Properties (Typical values at room temperature):
Hardness: 470-530 Brinell hardness number (HBW)
Yield Strength: ≥1300 MPa
Tensile Strength: ≥1550 MPa
Elongation: ≥8%
Impact Toughness: ≥24 J/cm² (at -20°C)
Applications:
NM500 steel is commonly used in mining machinery, construction machinery, cement industry equipment, and other applications requiring high wear resistance.
Weldability:
NM500 steel, like AR500, requires careful consideration during welding due to its high hardness. Preheating and appropriate welding techniques are recommended to prevent cracking and ensure good weld integrity.
Availability:
NM500 steel plates and sheets are available in various thicknesses and dimensions from Chinese steel suppliers and manufacturers.
NM500 steel offers excellent abrasion resistance properties, making it suitable for demanding applications where wear resistance and durability are critical factors.
