High-temperature alloys are a class of metal materials that exhibit excellent performance in high-temperature environments. They are widely used in aerospace, petrochemical, energy, and other high-temperature industrial fields. Traditional metal materials often experience creep, oxidation, erosion, and corrosion issues under high-temperature conditions, while high-temperature alloys can maintain good mechanical properties, oxidation resistance, and corrosion resistance under these extreme conditions.
Here are several common high-temperature alloy grades:
A286: A286 high-temperature alloy is an iron-based alloy that possesses excellent high-temperature strength and oxidation resistance. It can be used for long periods at temperatures around 700°C and exhibits good creep and fracture toughness. A286 is commonly used in the manufacturing of bolts, springs, and other structural components operating at high temperatures.
Nimonic 80A: Nimonic 80A is a nickel-based high-temperature alloy that offers excellent high-temperature strength and creep resistance. It can be used for long periods at temperatures around 815°C and exhibits good oxidation and corrosion resistance. Nimonic 80A is commonly used in the manufacturing of turbine blades, combustion chamber components, and heat exchangers operating at high temperatures.
Nimonic 90: Nimonic 90 is a nickel-based high-temperature alloy that provides high strength and good oxidation resistance. It can be used for long periods at temperatures around 950°C and exhibits good corrosion resistance. Nimonic 90 is commonly used in the manufacturing of nozzles, combustion chamber components, and turbine components operating at high temperatures.
GH1140: GH1140 is an iron-based high-temperature alloy that offers good high-temperature strength and oxidation resistance. It can be used for long periods at temperatures around 1000°C and exhibits good corrosion resistance. GH1140 is commonly used in the manufacturing of bolts, springs, and other structural components operating at high temperatures.
GH3625: GH3625 is a nickel-based high-temperature alloy that provides excellent high-temperature strength and oxidation resistance. It can be used for long periods at temperatures around 1050°C and exhibits good corrosion resistance. GH3625 is commonly used in the manufacturing of combustion chamber components, turbine blades, and heat treatment equipment operating at high temperatures.
These high-temperature alloy grades play important roles in their respective application fields and provide reliable material solutions for industries and aerospace sectors operating in high-temperature environments.
Grade 660 (A-286)
Grade 660 (A-286)
Grade 660 (A-286). High temperature bolting material, expansion coefficient comparable to Austenitic Stainless Steels.
GRADE 660 (A-286)
UNS S66286 : ASTM A638 (VO1.03), A453 (VO1.01)
GENERAL SCOPE
Grade 660 is a precipitation hardening austenitic stainless steel widely used for high temperature fastening and bolting materials. Its relatively high nickel content for a stainless steel means that is sometimes categorized as a nickel alloy. The grade is commonly used for operating temperatures up to 700°C (1300°F).
