Product Details

20mm Thick HB450 Wear Resistant Steel Sheet is widely used in mining, heavy machinery, construction, and material handling industries. With a hardness range of approximately 420–480 HBW, HB450 wear resistant steel provides an excellent balance between abrasion resistance, impact strength, and service life.

A 20mm thick wear resistant steel sheet is commonly selected for heavy-duty equipment because it can withstand both severe wear and high impact loads in harsh working environments.

What is 20mm Thick HB450 Wear Resistant Steel?

HB450 wear resistant steel is a quenched and tempered steel plate designed for abrasive applications. The 20mm thickness offers strong structural support while maintaining high wear resistance.

Thickness: 20mm
Hardness: 420–480 HBW
Yield Strength: ≥ 1100 MPa
Tensile Strength: 1250–1600 MPa

Why is Wear Resistant Steel So Thick?

Many buyers wonder why wear resistant steel plates are often supplied in thick sizes such as 20mm, 25mm, 40mm, or even thicker. The main reason is that wear resistant steel must resist both surface abrasion and mechanical impact.

Longer wear life: Thicker plates allow more material to wear away before replacement is needed.
Better impact resistance: Heavy-duty applications generate high impact forces.
Structural strength: Thick plates help equipment maintain stability under load.
Lower maintenance costs: Longer service life reduces downtime and replacement frequency.

In severe mining and quarry applications, thin plates wear out quickly, while thick wear plates can significantly improve equipment life.

Common Thickness Range of Wear Resistant Steel Plates

Thickness	Application	Wear Level
3–10mm	Light wear equipment	Moderate
10–20mm	Buckets, hoppers, dump trucks	High
20–50mm	Mining, crushers, heavy machinery	Very High
50mm+	Extreme wear environments	Extreme

Advantages of 20mm HB450 Wear Plate

Excellent abrasion resistance
Strong impact performance
Extended equipment life
Reduced maintenance costs
Good balance of hardness and toughness

Typical Applications

Mining truck liners

How to Choose the Right Thickness?

The right thickness depends on material type, wear severity, and impact load. For moderate wear, 10–16mm may be sufficient. For heavy mining and crushing equipment, 20mm or thicker is usually recommended.
