Hastelloy 276 Canted Coil Springs for Extreme Environments

In industries where corrosion, high temperatures, and cyclic stresses compromise conventional springs, Hastelloy 276 canted coil springs provide unmatched reliability. Crafted from Hastelloy C-276 alloy—a nickel-molybdenum-chromium superalloy—these springs excel in the world’s most aggressive operational environments.

Why Hastelloy C-276 Alloy?

Hastelloy C-276 (UNS N10276) is a nickel-molybdenum-chromium-iron-tungsten alloy renowned for:

  • Exceptional corrosion resistance against chlorides, sulfuric/hydrochloric acids, and oxidizing media
  • Zero susceptibility to chloride-induced stress corrosion cracking (SCC)
  • Superior pitting/crevice corrosion resistance
  • High strength & ductility from -253°C to 1093°C

Key Advantages of Hastelloy 276 Canted Coil Springs

1. Unparalleled Corrosion Resistance

Survives prolonged exposure to harsh chemicals (e.g., sulfuric acid, chlorides) where standard springs fail. Eliminates premature corrosion failures in chemical processing equipment.

2. Superior Fatigue Life

Maintains structural integrity under high-stress cyclic loading. Resists micro-crack formation for reliable performance in vibrating/pulsating systems.

3. High-Temperature Stability

Operates continuously from cryogenic (-253°C) 에 elevated temperatures (1093°C). Retains elastic modulus (~205 GPa) and tensile strength where other alloys soften.

4. Consistent Spring Force

Delivers precise, stable elastic force under mechanical stress. Resists permanent deformation even after prolonged compression.
