Alloy 330 (UNS N08330) is an austenitic, nickel-chromium-iron-silicon alloy that has outstanding resistance to oxidation and carburization up to 2200°F with high strength. The excellent resistance to oxidation and carburization is provided by the high nickel and chromium content of the alloy, further enhanced by its silicon content. Alloy 330's ultra high nickel content of 34 to 37% also provides high resistance to chloride stress corrosion cracking and embrittlement from the precipitation of sigma phase in most furnace atmospheres. Alloy 330 also has a low coefficient of expansion, excellent ductility, and high strength.

ASTM B535 N08330 Tube Mechanical Properties
The main mechanical properties are elasticity, plasticity, stiffness, aging sensitivity, strength, hardness, impact toughness, fatigue strength and fracture toughness.
Elasticity: Metal material deforms when it is subjected to external force. When the external force is removed, it can restore its original shape.
Plasticity: The ability of ASTM B535 N08330 ASTM B535 to produce permanent deformation without causing damage under external forces.
Stiffness: The ability of ASTM B535 N08330 ASTM B535 to resist elastic deformation under stress.
Strength: The ability of ASTM B535 N08330 ASTM B535 to resist deformation and fracture under external forces.
Hardness: The ability of ASTM B535 N08330 ASTM B535 to resist the pressure of a harder object into it.
Impact toughness: The ability of ASTM B535 N08330 ASTM B535 to resist fracture under impact loading.
Fatigue strength: The maximum stress that does not cause fracture when ASTM B535 N08330 ASTM B535 is subjected to numerous repeated or alternating loads.
Fracture toughness: a performance index used to reflect ASTM B535 N08330 ASTM B535 is ability to resist crack instability and expansion.
