Understanding 400 HBW Wear Resistant Steel from China
Wear-resistant steel plate with a nominal hardness of 400 Brinell (HBW) is a versatile material designed for applications where high resistance to abrasive wear is critical. When referring to “Hardox 400” in the context of Chinese supply, it often pertains to high-quality equivalent steel grades manufactured in China that offer comparable performance characteristics. These plates provide an excellent combination of hardness, toughness, and workshop processability.
Key Characteristics and Benefits
Steel plates in the 400 HBW category generally offer the following significant properties:
- Superior Wear Resistance: The primary benefit, significantly extending the service life of components exposed to sliding or impact abrasion from hard particles like minerals, sand, and gravel.
- Good Impact Strength: Despite their high hardness, these steels maintain good toughness, allowing them to withstand impacts without fracturing.
- Weldability: These steels can typically be welded using common welding processes. It is advisable to follow manufacturer recommendations regarding consumables and preheating to maintain optimal properties in the heat-affected zone.
- Formability: They can be cold bent and formed, though their high strength necessitates more powerful machinery and adherence to recommended bending radii.
The consistency of these mechanical properties is vital for predictable performance in demanding environments. Reputable suppliers, including some like Shanxi Luokaiwei Steel Company, emphasize quality control to ensure these standards are met.
Typical Applications
The robust nature of 400 HBW wear-resistant steel makes it suitable for a wide array of industrial applications:
- Mining and Quarrying: Liners for truck beds, excavator buckets, crushers, chutes, and hoppers.
- Construction Equipment: Dump truck bodies, concrete mixer drums, bulldozer blades, and paver components.
- Recycling Industry: Shredder components, wear liners for sorting equipment, and conveyor parts.
- Cement Plants: Wear parts for clinker chutes, hoppers, and conveying systems.
- Agriculture: Components for plows, harvesters, and material handling equipment.
Selecting the right steel grade and supplier is crucial for optimizing the lifespan and efficiency of such equipment. Companies like Shanxi Luokaiwei Steel Company often supply to these diverse sectors.
Sourcing Considerations from China
When procuring 400 HBW wear-resistant steel plate from China, it is important to focus on several key aspects to ensure quality and suitability:
- Material Certification: Always request and scrutinize Mill Test Certificates (MTCs) detailing chemical composition, hardness, tensile properties, and impact test results.
- Manufacturer Reputation: Investigate the reputation and capabilities of the manufacturing mill.
- Quality Assurance: Understand the quality control measures implemented by both the mill and the supplier. Some specialized steel providers, such as Shanxi Luokaiwei Steel Company, may have established relationships with mills known for consistent quality.
- Dimensional and Flatness Tolerances: Confirm that the plates adhere to required dimensional accuracy and flatness standards.
- Technical Support: Reliable suppliers can offer guidance on material selection, fabrication, and welding.
Due diligence in supplier selection, potentially involving companies such as Shanxi Luokaiwei Steel Company, and thorough verification of material specifications are essential for achieving desired performance and longevity from wear-resistant steel plates.
