Specialized structures and wear-prone steels are designed for heavy-duty and high-wear conditions in construction machinery. Typical components include: hydraulic shears for construction machinery (wear-resistant steel); screeds for construction machinery (wear-resistant steel); and X-frames for construction machinery (high-strength steel).
Wear-resistant steel is available in a full range of specifications, with good plate shape and excellent bending performance. It can be processed and delivered in one stop and is suitable for the harsh working conditions of engineering machinery.
Widely used in core wear-resistant parts and high-strength structural components of various engineering machinery such as excavators, conveyors, and road construction machines, adaptable to complex operating scenarios such as heavy loads, impacts, and gravel abrasion.

Frequently Asked Questions
Q: What is the capacity of your bending machines?
A: Our company has three bending machines, covering the 1000-3600 ton range. They are fully equipped with molds, ensuring high bending precision and stable forming, meeting the bending needs of various wear-resistant steel and high-strength steel parts.
Q: Can wear-resistant steel be rolled into plates?
A: Yes, our plate rolling machines can professionally roll wear-resistant steel and high-strength steel, achieving cold rolling with high precision and no cracking or deformation, meeting the processing needs of engineering machinery cylinders, curved guard plates, and other components.
Q: How do you solve the drilling problem for wear-resistant steel?
A: Our company uses special carbide drill bits for efficient drilling.
Q: What is the flatness of your wear-resistant steel products?
A: Our company's national standard steel plates have a surface unevenness of ≤5mm/1000mm, and our European standard steel plates have a surface unevenness of ≤3mm/1000mm. If there are special requirements, we can further level the surface to improve the unevenness.
Q: Is wear-resistant steel prone to cracking during welding?
A: No, our wear-resistant steel can be welded using a preheating process, resulting in a stable heat-affected zone and making it less prone to cracking after welding. It is suitable for assembling structures such as buckets and truck bodies.
