NM550 Abrasion Resistant Steel Plate

NM550 Abrasion Resistant Steel Plate

NM550 wear-resistant steel plate is a kind of high-strength wear-resistant steel plate, which is widely used in various engineering and mechanical equipment.

NM550 wear-resistant steel plate characteristics

1. High hardness:

With a hardness of up to 550HBW, NM550 wear-resistant steel has excellent anti-wear properties and can effectively resist various wear and scratches.

2. Excellent wear resistance:

NM550 wear-resistant steel plate is made of high-strength alloy material, has extremely high wear resistance, can withstand high-strength impact and heavy load, effectively extend the service life.

3. High strength:

NM550 wear-resistant steel plate has high yield strength and tensile strength, and can withstand large internal and external forces to ensure the stability and safety of the structure.

4. Low temperature impact toughness:

NM550 wear-resistant steel plate can still maintain good impact toughness in low temperature environment, not easy to break, suitable for a variety of harsh working conditions.

The chemical composition of nm550 steel is as follows:

• Carbon (C) content :0.30-0.38%
• Silicon (Si) content :0.20-0.40%
• Manganese (Mn) content :1.30-1.70%
• Phosphorus (P) content :≤0.025%
• Sulfur (S) content :≤0.010%
• Chromium (cr) content :≤0.30%
• Nickel (Ni) content :≤0.30%

Mechanical property

• Tensile strength: The tensile strength of nm550 steel is 550MPa, which is a high-strength steel with excellent strength.
• Yield strength: The yield strength of nm550 steel is 550MPa, and the high yield strength indicates that it has good plastic deformation ability.
• Elongation: the elongation of nm550 steel is 16%, and the large elongation indicates that it has good plasticity and is not easy to break.
• Impact toughness: The impact toughness of nm550 steel is ≥27J/cm², which has good impact resistance.
