Wear-Resistant Steel NMS450-1, NMS450-2
General Technical Characteristics
Wear-resistant steel grades NMS450-1 and NMS450-2 are high-strength plate steels with a nominal hardness of approximately 450 HB, designed for operation under intensive abrasive wear and moderate impact conditions.
These grades belong to quenched and tempered (Q&T) steels, providing an optimal balance of hardness, strength, and toughness.
They are supplied in plate form with thicknesses typically ranging from 6 mm up to 100 mm.
Chemical Composition and Mechanical Properties
NMS450-1 and NMS450-2 steels feature an alloyed chemical composition including carbon (C), manganese (Mn), silicon (Si), and alloying elements such as chromium (Cr), nickel (Ni), molybdenum (Mo), and boron (B).
The difference between -1 and -2 versions generally lies in impact toughness and performance at lower temperatures.
Mechanical properties:
- hardness: ~430–480 HB
- yield strength: from 1000–1250 MPa
- high resistance to abrasive wear
- good impact toughness (especially NMS450-2)
- consistent properties through the plate thickness
Applications
NMS450-1 and NMS450-2 plates are widely used across various industries:
- mining industry
- quarry and construction equipment
- buckets, blades, and cutting edges
- crushing and material handling equipment
- hoppers, chutes, and liners
These steels are ideal for components exposed to friction, impact, and abrasive environments.
Features
Key advantages of NMS450 steel include:
- optimal balance of hardness and impact strength
- enhanced wear resistance
- good weldability with proper procedures
- potential weight reduction due to high strength
- extended equipment service life
NMS450-2 is recommended for more demanding conditions where higher impact toughness is required.
Standards and Supply Formats
NMS450 steel is produced according to manufacturer specifications aligned with international standards such as EN and ASTM.
Supply formats:
- standard size plates
- cut-to-size processing
- plasma and oxy-fuel cutting
- custom parts based on drawings
- optional machining services
