Quard 400 Steel Plates

Quard 400 is a brand of abrasion-resistant steel plates manufactured by NLMK Clabecq in Belgium. Here’s an overview of Quard 400 steel plates:

1. **Material Composition**: Quard 400 plates are made from high-quality alloyed steel with a combination of carbon, manganese, chromium, boron, and other elements. These elements are carefully balanced to provide high hardness, strength, and toughness.

2. **Properties**:

   - **High Hardness**: Quard 400 plates typically have a hardness of around 400 HBW (Brinell Hardness Number), which makes them highly resistant to abrasion and wear.

   - **Excellent Abrasion Resistance**: They are designed to withstand severe abrasion and impact in tough industrial applications.

   - **Good Formability**: Despite their hardness, Quard 400 plates can be cold formed and welded using conventional methods. However, preheating and controlled heat input may be required depending on plate thickness and application.

   - **High Yield Strength**: Quard 400 plates offer high yield strength, ensuring structural integrity under heavy loads and impact.

3. **Applications**:

   - **Mining Equipment**: Quard 400 plates are commonly used in the manufacturing of mining truck bodies, bucket liners, and wear-resistant parts for excavators and loaders.

   - **Quarrying**: They find applications in quarrying equipment such as crusher liners, grizzly bars, and screens.

   - **Construction Machinery**: Quard 400 plates are used in construction and earthmoving machinery for components subjected to abrasive wear, such as dump truck bodies and loader buckets.

   - **Recycling**: They are also suitable for recycling machinery where wear resistance is critical for components like shredder blades and conveyor belts.

4. **Availability**: Quard 400 plates are available in various thicknesses and dimensions to suit different application requirements in heavy industries. They are typically supplied with test certificates to ensure compliance with specified mechanical properties and quality standards.

**Price Information**:

Pricing for Quard 400 plates can vary based on several factors:

- **Thickness and Dimensions**: Thicker plates and larger sizes generally command higher prices due to increased material costs and manufacturing complexity.

- **Quantity**: Bulk orders often result in discounted prices per unit due to economies of scale.

- **Supplier**: Prices may vary between suppliers based on their overhead costs, delivery terms, and market conditions.

- **Market Demand**: Prices can fluctuate based on global steel market trends and raw material costs.

For specific pricing and availability, it is recommended to contact steel suppliers or distributors specializing in abrasion-resistant steel plates. They can provide quotes based on your specific requirements, volume needs, and current market conditions.
