Wear-Resistant Steel NM400 – NM600

Wear-Resistant Steel NM400 – NM600

General Technical Characteristics

Wear-resistant steel grades NM400, NM500, and NM600 are high-strength plate steels with increased hardness, designed for operation under severe abrasive wear conditions. The key parameter of these grades is Brinell hardness: 400, 500, and 600 HB respectively. NM steel features good weldability (when proper procedures are followed), high strength, and excellent resistance to mechanical stress.

It is supplied in sheet/plate form with a wide thickness range (from 4 mm up to 100 mm and more), making it a versatile solution for industrial applications.

Chemical Composition and Mechanical Properties

NM400–NM600 wear-resistant steel has a carefully balanced chemical composition including carbon (C), manganese (Mn), silicon (Si), and alloying elements such as chromium (Cr), nickel (Ni), molybdenum (Mo), and boron (B).

This composition provides:

• high hardness and wear resistance
• good impact toughness
• resistance to deformation

Mechanical properties:

• hardness: 400–600 HB
• yield strength: from 1000 MPa
• excellent resistance to abrasive wear
• long service life in demanding environments

Applications

NM400, NM500, and NM600 plates are widely used in industries where maximum wear resistance is required:

• mining industry
• quarry and construction equipment
• manufacturing of buckets, blades, and hoppers
• crushing and screening equipment
• cement and metallurgical plants

Wear-resistant steel is ideal for components exposed to constant friction and impact loads.

Features

The key advantage of NM steel is a significant increase in equipment service life and reduced maintenance costs. The use of NM400–NM600 wear plates allows you to:

• reduce material thickness without loss of strength
• decrease structural weight
• improve equipment efficiency
• minimize downtime

The steel is suitable for cutting, bending, and machining when proper guidelines are followed.

Standards and Supply Formats

NM wear-resistant steel is produced in accordance with international and mill standards, including equivalents to EN and ASTM specifications.

Supply formats:

• standard size plates
• custom cutting
• plasma and oxy-fuel cutting
• optional machining services
