Stainless Steel Triangle Wire

Stainless steel triangle wire is a type of special-shaped stainless steel wire with a triangular cross-section. It is typically made from stainless steel containing chromium, nickel, and other alloying elements. Through precise manufacturing processes such as cold drawing or rolling, the wire achieves an accurate triangular shape and consistent dimensions, providing superior strength, corrosion resistance, and precision.

Material Grades

304 Stainless Steel Triangle Wire

304 grade features excellent corrosion resistance, heat resistance, and workability. It is non-magnetic and resists general acid and alkali corrosion. 304 stainless steel triangle wire is widely used in daily applications, decorative parts, and industrial equipment where corrosion resistance requirements are moderate.

316 Stainless Steel Triangle Wire

Based on 304, 316 stainless steel contains added molybdenum (Mo), which significantly enhances its resistance to chloride corrosion. It performs exceptionally well in marine environments, chemical plants, and medical devices, where high corrosion resistance is critical.

430 Stainless Steel Triangle Wire

430 is a ferritic stainless steel with moderate corrosion resistance and magnetic properties. It offers a more economical solution for applications where corrosion resistance is not the top priority, such as decorative trims, household appliances, and interior components.

E200 Stainless Steel Triangle Wire

E200 is a high-performance, non-magnetic stainless steel with a high manganese content, specially developed for wear-resistant applications. It offers excellent hardness, precision, and durability, making it ideal for coal washing screens, mining sieves, and filter baskets used in the mining and coal processing industries.

Manufacturing Process

Cold Drawing Process

The process begins by forming stainless steel rod into round wire, which is then drawn through triangular dies at room temperature under controlled tension. Each pass gradually shapes the wire into a triangular profile.
Cold drawing increases the wire’s tensile strength, dimensional accuracy, and surface smoothness, resulting in high-precision finished products.

Rolling Process

In this method, heated stainless steel billets are passed through rollers with triangular grooves, shaping the material into triangle wire. This process is suitable for larger-size wires and offers high production efficiency.
However, its dimensional tolerance and surface finish are generally lower than cold drawing and often require subsequent polishing or finishing.

Key Features

• High Strength
  Stainless steel triangle wire offers excellent tensile and yield strength, ensuring resistance to deformation and fracture even under heavy loads.
• Superior Corrosion Resistance
  A dense passive oxide film forms on the surface, protecting it from rust and corrosion in harsh environments, ensuring a long service life.
• High Dimensional Precision
  Produced using precision dies and advanced processing, it maintains tight tolerances, suitable for high-accuracy assembly applications.
• Excellent Surface Finish
  After cold drawing or polishing, the wire surface becomes smooth, reflective, and uniform, reducing friction and wear during operation.

Applications

1. Screening and Filtration

Used in mining, coal, and construction industries, stainless steel triangle wire is commonly fabricated into screen meshes, filter panels, and sieve drums. Its high wear resistance and strength help improve screening efficiency and extend equipment lifespan.

2. Architectural Decoration

Applied in building facades, railings, handrails, and decorative trims, triangle wire enhances aesthetic appeal and structural integrity, giving modern architectural projects a clean, industrial appearance.

3. Industrial Filtration

In chemical, food, beverage, and pharmaceutical industries, triangle wire is used to manufacture filters and strainers. Its uniform gaps and corrosion resistance ensure high filtration efficiency and product purity.

4. Mechanical Engineering

Serves as a raw material for mechanical components such as gears, springs, and chains, offering durability and mechanical reliability in demanding working conditions.

5. Other Applications

Also used in electronics, aerospace, and automotive manufacturing, such as EMI shielding meshes, structural reinforcements, and seat springs, where strength, precision, and corrosion resistance are essential.

Conclusion

Stainless steel triangle wire combines precision geometry, high strength, and superior corrosion resistance, making it an ideal choice for industrial, architectural, and filtration applications. Whether made from 304, 316, 430, or E200 stainless steel, it delivers long-term performance and reliability even in the most challenging environments.
