HIGH TEMPERATURE ALLOY
Extreme Heat. Extreme Performance. High Temp Alloys Built to Endure.
Introduction to High Temperature Alloy
High-temperature alloys, also known as superalloys, are crafted for exceptional strength and stability in extreme heat. Typically based on nickel, cobalt, or iron, they offer impressive strength that typically ranges between 500 – 1,500 MPa (72.5 – 217.5 ksi) and resist heat, oxidation, and corrosion, even at temperatures up to 1,200°C.
These alloys are enhanced through advanced techniques like precipitation hardening (particularly nickel-based ones) and powder metallurgy, ensuring durability and performance under stress. With added elements like chromium and aluminum for stability, they are essential in industries like aerospace and power generation, where reliability in extreme environments is key.
Benefits of High Temp Alloy
Our selection of high-temperature alloys are designed to deliver exceptional performance in the most demanding environments. The benefits of these advanced materials include:
- Stay strong at high temperatures
- Resist oxidation and scaling
- Durable and long-lasting
- Less maintenance needed
- Easy to shape and work with
- Can be coated for extra protection in tough environments
Grades of High Temperature Alloy
Carbon steel and HSLA steel are the main types specifically classified as shipbuilding steel. Other types, like nickel steel, stainless steel, duplex stainless steel, maraging steel, weathering steel, and tool steel, are also used in shipbuilding but are not exclusively used for it.
- Nickel-Based Alloys: Inconel 625 (NA21), Inconel 718 (NA51), Hastelloy X (N06002), Nimonic 90 (N07090), Haynes 230 (N06230), Waspaloy (N07001), etc.
- Cobalt-Based Alloys: Haynes 188 (R30188), Haynes 25 (L-605) (R30605), Stellite 6B (UNS R30016), MAR-M 509 (N15500), Ultimet (R31233), etc.
- Iron-Based Alloys: Incoloy 800 (N08800), Incoloy 825 (N08825), A286 (S66286), Hastelloy S (N06635), RA330 (N08330), etc.
