ASTM B444 UNS N06625 Inconel Alloy 625 Seamless Nickel Pipe & Tube Supplier Price Per KG
Inconel 625 alloy is a solid solution strengthened nickel-based deformed high-temperature alloy with molybdenum and niobium as the main strengthening element. It has excellent corrosion resistance and high oxidation properties. It has good tensile properties and fatigue properties from low temperature to 980°C, and is resistant to Stress corrosion in salt spray atmosphere. Alloy 625 has good processing and welding properties.
What Are The Features of Inconel Alloy 625?
Excellent corrosion resistance:
Inconel 625 maintains excellent corrosion resistance in harsh
chemical environments.
It has excellent antioxidant, acid and alkali resistance, stress
corrosion cracking and other properties.
It is widely used in corrosive environments such as chemical
industry and ocean.
Excellent high temperature performance:
Maintains good mechanical strength and oxidation resistance at
temperatures up to 816°C (1,500°F).
Excellent resistance to creep and thermal fatigue at high
temperatures.
Good mechanical properties:
Has high strength, toughness and hardness.
It can withstand various processing and stress and is suitable for
complex forming processes.
Excellent weldability:
The welded joint has high strength and good heat resistance.
Post-weld heat treatment is simple and less likely to cause
heat-affected zone problems.
Excellent thermal stability:
Low thermal expansion coefficient and good thermal conductivity.
Strong resistance to thermal stress corrosion cracking.
