Vanadium Screws

Standard parts are universal components designed, manufactured, and inspected according to national, industry, or international standards (e.g., dimensions, materials, performance, structure, tolerances, etc.). Their core characteristics are standardization and versatility. They can be used interchangeably across different devices and scenarios, eliminating the need for custom customization. They are essential components for achieving efficient manufacturing, reducing costs, and ensuring quality in industrial production. They usually include fasteners (screws, nuts, bolts, etc.), transmission components and connectors.

Vanadium screws are fasteners made from vanadium alloys. The most common type is "vanadium steel screw"—a type of vanadium steel with vanadium added as an alloying element(typically 0.1%-0.5%) to carbon steel or alloy steel. These main feature grades like 40CrV, 50CrV4, and 15CrV3. Vanadium's effects on screw material are primarily reflected in three key aspects: grain refinement, high-temperature stability and surface protection.

Due to their combined properties of high strength, heat resistance and fatigue resistance, vanadium screws are primarily used in harsh industrial environments such as heavy-duty applications, rather than in ordinary civilian settings. The main applications include: construction machinery(heavy-load structural connections for excavators, loaders, and cranes), the automotive industry, energy equipment (fixing key components of boilers, steam turbines, and wind turbines), marine engineering, chemical equipment, corrosion-resistant or heat-resistant connections for high-temperature equipment, high-end manufacturing etc.
