Inconel 600/601:
Standard for Extreme Heat
When furnace temperatures rise above 1000°C, ordinary stainless steel degrades rapidly. Inconel 600 (N06600) remains stable and resistant to oxidation and carburization. Upgrading to Inconel 601 adds Aluminum for even greater resistance to cyclic heating and thermal shock.
Ideal For: Furnace muffles, retort seals, heat exchanger tubing, and chemical processing equipment where high-temperature integrity is critical.
- Resistant to Chloride-ion Stress Corrosion Cracking.
- Operates in oxidizing environments up to 1150°C.
- Available in: Seamless Pipe, Plate, and Round Bar.
Inconel 625:
The Ultimate Corrosion Shield
Inconel 625 (N06625) is the workhorse of the offshore and chemical industries. The addition of Molybdenum and Niobium creates a stiff matrix that resists pitting and crevice corrosion in severe sea water and sour gas environments.
Ideal For: Sea water piping, offshore stack liners, acid production plants, and pollution control equipment.
- Immune to Chloride Pitting & Crevice Corrosion.
- High Tensile Strength without heat treatment.
- Excellent weldability (overlay/cladding).
Inconel 718:
Powering Jet Engines
Inconel 718 (N07718) is a precipitation-hardenable Nickel-Chromium alloy containing Niobium. It is designed to withstand high stress at temperatures up to 700°C (1300°F). It accounts for over 30% of the total mass of a modern aircraft engine.
Ideal For: Gas turbine blades, rocket motors, spacecraft structural components, and high-strength fasteners.
- Exceptionally high yield & tensile strength.
- Good ductility and rupture strength.
- Age-hardenable (solution treated + aged).
