441 stainless steel spring wire

Stainless steel spring wire offers exceptional corrosion resistance, eliminating the need for additional protective coatings. This makes it an ideal choice for springs operating in various corrosive environments, high temperatures, and locations where maintenance or replacement is challenging.

All BS Stainless spring wires, including the high-quality 441 stainless steel spring wire, are manufactured to stringent quality standards, ensuring reliability in demanding applications. Key features include:

• Tensile Strength: Consistent spring-forming capabilities for durability.
• Surface Finish & Soap Coating: Provides lubrication to facilitate high-speed spring formation, promoting optimal coiling characteristics.
• Cast & Helix: Enhances product performance for long-lasting usage.

The unique properties of BS Stainless steel spring wires are achieved through precision cold drawing, allowing them to retain tensile strength at operating temperatures up to 250°C. 441 stainless steel spring wires can withstand lower stress levels at even higher temperatures, up to 450°C.

441 Stainless Steel Alloy Description:

Type 441 is an 18% chromium-bearing ferritic stainless steel stabilized with columbium, offering superior high-temperature strength compared to types 409 and 439. It also provides reliable corrosion resistance in exhaust gas environments, similar to 439 and 18 Cr-Cb alloys.

Stainless steel spring wires, such as 441 stainless steel, are widely used in producing compression springs, extension springs, and torsion springs for demanding applications.
