Tech Spring Manufacturing Corp. is a high quality Metal Spring Manufacturer in Taiwan, offering Wave Springs, Retaining Rings and Constant Force Spring with good quality and reasonable price.

Haynes 25 / L605 (For Springs)

Haynes 25/L605 is a Cobalt-Nickel-Chromium-Tungsten alloy that combines good high temperature strength with good resistance to oxidising environments up to 980°C (1795°F) for long exposures. It also has excellent resistance to sulphidation. It can be used for any TSMC spring product such as wave springs, retaining rings and compression springs.
Haynes 25/L605 is also known as Udimet L605.
