Helical Spring

Facing These Sealing Problems?

• High-Temp Relaxation & Leaks?
  → Our Inconel 718 springs offer superior anti-relaxation for reliable sealing above 700°C.
• Extreme Chemical Corrosion?
  → Hastelloy C-276 springs provide ultimate resistance to acids, alkalis, and chlorides.
• Need the Ultimate Balance of Strength, Corrosion & Fatigue Resistance?
  → Elgiloy® Cobalt-Chromium springs deliver exceptional high strength, good corrosion resistance, and unmatched fatigue life for dynamic applications.
• Seeking Optimal Cost-Performance?
   → Inconel 625 springs excel with an outstanding balance of corrosion resistance, fatigue strength, and moderate high-temperature capability.
• Cryogenic Embrittlement?
  → Our low-temperature alloys retain critical elasticity and toughness in deep cryogenic environments.

Industries

Helical Spring Seals are trusted across high-integrity sealing environments, including:

• Aerospace: fuel delivery systems, engine components, and actuator seals
• Medical: sterilizer valves, fluidic control in surgical and diagnostic devices
• Energy: hydrogen handling, LNG compression, geothermal and nuclear sealing
• Semiconductor: vacuum chamber interfaces, wafer transfer sealing, UHV equipment
• Industrial Automation: robotic arm sealing, hydraulic or pneumatic rotary joints

We select materials based on operating temperature, chemical compatibility, and certification requirements (e.g., NACE, FDA, or ASME standards).

Custom Sizes

We can manufacture Helical Wound Springs in any size diameter, from 0.86mm up to approximately 15mm. The functional length of the part may be small at very large diameters. Please contact us with your requirements.

Custom material widths, and thicknesses can also be created. No additional tooling charges are required for special diameters or alternate material slit widths.

Material Options

We offer a broad selection of corrosion-resistant and high-performance alloys to ensure optimal spring function across temperature extremes and aggressive media.

• Inconel®– High strength and oxidation resistance up to 650°C, ideal for energy, aerospace, and cryogenic sealing.
• Elgiloy® – Superior fatigue resistance and corrosion performance, preferred in dynamic or mission-critical seals.
• Hastelloy® – Exceptional resistance to oxidizing acids and aggressive chemicals, suitable for process control and semiconductor systems.
• 17-7PH Stainless Steel – Balanced strength and corrosion resistance for general-purpose industrial use.
• Other Material – Contact Us

We select materials based on operating temperature, chemical compatibility, and certification requirements (e.g., NACE, FDA, or ASME standards).

Pre Cut And Welded

Laser welding is useful in a variety of situations and product applications. One of the most useful is for welding spring energizers. Our location laser welds V springs, U springs, helical springs, and canted spring energizer products. Contact Handa for more information.

Provide the desired center-line diameter, and we are happy to coil, cut, and weld the helical spring(s) you need using our state-of-the-art Laser Weld Technology.
