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.

Incoloy 800HT (For Springs)

This Nickel-Chromium-Iron alloy has the same basic composition as Incoloy 800, but has significantly higher creep rupture strength, resultant from the close control of the carbon, aluminium and titanium contents. It has good strength and excellent resistance to oxidation and carburisation in high temperature atmospheres.It also resists corrosion in many aqueous environments.
Incoloy 800HT is also known as Nicrofer 3220 HP.

Nickel Base Wire for wire springs, flat springs and wire products

Key Features
  • Higher creep rupture strength than Incoloy 800 due to close control of C, Al, Ti
