Inconel 600 bars and Inconel 713 nickel alloy round bars
Inconel 600 bars and Inconel 713 nickel alloy round bars
Inconel 600 and Inconel 713 are nickel-based superalloy bars, commonly used in round bars for high-temperature and corrosive environments, exhibiting excellent strength and oxidation resistance. Inconel 600 bars are primarily used in general high-temperature applications (such as chemical and aerospace), while Inconel 713 bars are a cast alloy commonly used in turbine components. Both are supplied in bar, rod, and various profile forms to meet the needs of demanding industries. They are essentially special types of nickel alloys that exhibit superior performance in environments where ordinary steel fails. Inconel 713 bars have a higher nickel and chromium content, thus improving specific strength and creep resistance.
What is Inconel 713 material?
Inconel 713 is a nickel-based superalloy raw material. This alloy is specifically designed for cast components used in gas turbines and the aerospace industry, and is known for its high strength and oxidation resistance.
Inconel 600 Bars (UNS N06600)

Applications: Chemical processing (reactors, heat exchangers), aerospace (turbine seals, exhaust systems), power generation (nuclear reactors), and marine applications.
Forms: Available in round bars, bars, and thick bars. Surface treatments include hot rolling, cold drawing, and bright finishing.
Inconel 713 Bars (UNS N07713)
Type: Cast nickel-based superalloy.
Properties: High strength and good elongation, designed for extreme high-temperature environments, especially suitable for cast parts.
Applications: Critical components in gas turbines (jet engines), industrial gas turbines, and other high-stress, high-temperature applications.
Forms: Typically round bars, performing well in construction and harsh industrial environments.
