GENERAL APPLICATION:
Electro Polishing Quality (EPQ) wires are stainless steel wires designed for applications where a clean, smooth and bright surface finish is important. These wires are manufactured with controlled strength and dimensional accuracy so they can be easily formed into different shapes without affecting the surface quality. EPQ wires are widely used in industries where hygiene, appearance and corrosion resistance matter. Their mirror-bright finish makes them suitable for both functional and decorative stainless steel components.
Key Features and Benefits
Electro Polishing Quality wires are designed to provide reliable performance in fabrication and forming applications.
- Mirror Bright Surface Finish: The EPQ finish provides a clean and smooth appearance, ideal for products that require a polished or decorative surface.
- Controlled Mechanical Strength: Tensile strength ranging from around 700 to 1200 N/mm² supports strong and durable formed parts.
- Multiple Hardness Options: Available in conditions such as 1/8 hard, 1/4 hard, 1/2 hard, 3/4 hard, spring hard and full hard to match different forming needs.
- High Dimensional Accuracy: Manufactured within tight tolerance standards to ensure consistent quality and uniform diameter.
- Flexible Surface Options: Available in mirror bright EPQ finish, soap coated and matte finish depending on the application.
- Reliable Packaging Options: Supplied in coils or spools to support easy handling and efficient processing during manufacturing.
Specifications
EPQ wires are manufactured with controlled dimensions and mechanical strength to ensure reliable forming performance and a clean surface finish for stainless steel applications.
