ROCKHARD 400 PLATE About

Rockhard 400 Plate is a premium abrasion-resistant steel plate engineered for extremely high wear and impact conditions. Its made through quenching and tempering (Q + T) processes that optimize hardness and toughness simultaneously. This steel is widely used in mining, earthmoving, material handling equipment, heavy machinery parts, dump truck liners, hoppers, crushers, and structural components where high resistance to wear extends service life and reduces downtime.

Chemical Composition (Typical Ranges)

Composition can vary slightly by thickness and manufacturer, but a representative range for Rockhard 400 is:

Element	Typical % (max)
Carbon (C)	Up to 0.27% (varies with thickness)
Silicon (Si)	Up to 0.70%
Manganese (Mn)	Up to 1.60%
Phosphorus (P)	0.025%
Sulfur (S)	0.0100.025%
Chromium (Cr)	Up to 1.40% (varies)
Nickel (Ni)	Up to 1.50%
Molybdenum (Mo)	Up to 0.60%
Boron (B)	0.004%
Carbon Equivalent (CEV/CET)	Typical values 0.280.48 depending on thickness

Mechanical Properties

Property	Typical Value
Hardness	400 HBW nominal (BHN) High abrasion resistance
Yield Strength (min)	1000 MPa
Tensile Strength (min)	12501400 MPa
Elongation	1012%
Impact Toughness	Typically measured at low temp (e.g., 2745 J at 40 C)

Key Features & Benefits

High Abrasion Resistance: 400 BHN hardness gives excellent wear life in harsh service.
Good Toughness & Strength: High yield and tensile strength help withstand impact and heavy loads.
Heat-Treated (Q + T): Optimized balance of hardness plus ductility.
Weldable & Fabricable: Controlled chemistry supports reliable welding in field and fabrication work.

Typical Applications

Dump truck and trailer liners
Mining machinery (crushers, chutes, hoppers)
Loader and excavator buckets
Conveyor components
Earthmoving and heavy construction equipment
Industrial machinery where abrasion wear limits component life

Typical Dimensional Range

Thickness: 3 mm to 150 mm (sometimes up to 200 mm)
Width: 500 mm to 3000 mm
Length: 1000 mm to 12000 mm
