FAQ

Yes, titanium alloys (like Grade 5 or Beta-C) are utilized where extreme weight reduction, high strength-to-weight ratio, and specific chemical resistance are mandatory.

AISI 302 stainless steel can perform reliably in environments up to approximately 204°C (400°F) before experiencing thermal degradation of properties.

Standard carbon steel wave springs should not exceed approximately 121°C (250°F) to prevent excessive stress relaxation and loss of load capacity.

Elgiloy is a cobalt-chromium-nickel alloy renowned for high strength, exceptional fatigue life, and extraordinary corrosion resistance, commonly specified in oil & gas and medical implants.

Materials like AISI 302/316 stainless steel or Inconel retain excellent ductility, toughness, and mechanical performance at sub-zero and cryogenic temperatures without becoming brittle.

Cold-worked stainless steel (like AISI 302/316) exhibits slight magnetism due to the grain deformation during drawing and coiling, though 316 is substantially less magnetic than 302.

Common finishes include black oxide for mild corrosion resistance, zinc plating for sacrificial protection, oil dip for storage protection, and phosphate coatings.

Hydrogen embrittlement causes sudden, catastrophic brittle failure under tensile stress. It typically occurs after acid pickling or electroplating if the spring is not properly baked immediately.

A286 offers an excellent combination of high strength and corrosion resistance at elevated temperatures up to 538°C (1000°F), often utilized in aerospace applications.

Yes, Beryllium Copper is selected for applications requiring excellent electrical conductivity, non-magnetic properties, and strong corrosion resistance.

Superalloys like Inconel X-750 are recommended for extreme temperatures up to 700°C (1300°F) because they maintain high tensile strength and resist creep.

AISI 316 should be selected for superior resistance to pitting and corrosion in marine, chemical, and medical environments, though it possesses slightly lower mechanical strength than 302.

Carbon steel (SAE 1070-1090) and Stainless Steel (AISI 302 and 316) are the most prevalent materials for general and corrosion-resistant industrial environments.

Unlike stamped washers, edgewise coiled wave springs do not require custom stamping dies, making prototyping and low-volume custom configurations highly cost-effective.

Uniform wave spacing is critical. Imperfections or unequal wave heights lead to non-uniform load distribution, localized stress concentration, and premature fatigue failure.

Plain ends create localized point loads that can score, gall, or wear down soft metals like aluminum or plastic over repeated cycles. Shim ends should be specified for soft housings.

At high temperatures, both the physical dimensions expand and the material modulus drops. Clearances must be adjusted to prevent binding inside the bore due to thermal growth.

A nested spring provides an extremely steep, linear load-deflection curve, enabling high force delivery within a highly compressed, compact operating zone.

Yes, but shock loading drastically accelerates fatigue. Incorporating a higher safety factor, dampening mechanisms, or utilizing nested designs helps mitigate impact stresses.

The natural frequency depends on the spring rate and the active mass of the spring itself, following standard harmonic oscillator principles adjusted for multi-wave geometries.
