What are HB 400 Plates?
HB 400 Plates are a type of hardened steel plate designed to withstand extreme wear and tear. With a hardness rating of 400 HBW (Brinell Hardness), these plates are highly durable and resistant to abrasion, making them ideal for applications in industries such as mining, construction, and material handling. Their superior mechanical properties also make them a popular choice for heavy-duty equipment manufacturing.

Key Features of HB 400 Plates
- High Wear Resistance: Engineered to handle abrasive conditions, HB 400 Steel Plates excel in extending the life of equipment.
- Exceptional Strength: The high tensile strength of these plates ensures reliable performance under heavy loads.
- Versatility: These plates can be easily machined, welded, and formed to meet specific requirements.
- Corrosion Resistance: Designed to perform well even in harsh environments, these plates offer moderate corrosion resistance.
Benefits of Using HB 400 Plates
- Cost-Effective: By reducing wear and tear, these plates minimize maintenance costs and downtime.
- Extended Service Life: The high hardness level ensures prolonged durability, even in demanding conditions.
- Increased Productivity: Their ability to withstand abrasive forces leads to efficient operation and reduced replacement frequency.
- Customizable: Available in various sizes and thicknesses, Hardened 400 Plates can be tailored to meet specific needs.
Applications of HB 400 Plates
Hardened 400 Sheets are widely used across several industries for their durability and versatility. Some common applications include:
- Mining and Quarrying: Used in dump truck beds, crushers, and conveyor systems to handle abrasive materials.
- Construction: Ideal for manufacturing bulldozer blades, loaders, and excavator buckets.
- Material Handling: Utilized in chutes, liners, and hoppers to reduce wear caused by heavy materials.
- Agriculture: Employed in plow blades and tillage equipment for enhanced performance and longevity.
- Industrial Machinery: Applied in components that require high wear resistance, such as gears and rollers.
