718 Nick alloy Bar Stock

High-Strength, Heat-Resistant Superalloy for Extreme Environments

​Product Overview

Inconel 718 bar stock is a nickel-chromium-based superalloy strengthened by age-hardening, delivering exceptional strength and oxidation resistance at temperatures up to ​700°C (1292°F). Widely used in aerospace, oil & gas, nuclear energy, and high-end industrial applications, this material complies with ​ASTM B637, ​AMS 5662/5663, and other international standards. It is the premier choice for turbine blades, rocket engine components, and deep-sea drilling tools.

​Product Specifications

1. ​Material & Processing

• Composition: Nickel (Ni 50-55%), Chromium (Cr 17-21%), Iron (Fe balance), Niobium (Nb 4.75-5.5%)
• Standards: ASTM B637, AMS 5662, AMS 5663, DIN 17752
• Heat Treatment: Solution Annealed or Age Hardened
  2. ​Dimensions & Forms
• Diameter Range: Φ5mm to Φ300mm (custom sizes available)
• Surface Finish: Turned, Polished, Hot Rolled (Black)
• Length: Cut-to-Size (1m-6m) or Random
  3. ​Mechanical Properties
• Tensile Strength: ≥1275 MPa (Age Hardened)
• Yield Strength: ≥1035 MPa
• Elongation: ≥12%
• Hardness: ≥35 HRC

​Key Advantages

✅ ​High-Temperature Performance: Superior oxidation and creep resistance at 700°C.
✅ ​Corrosion Resistance: Resists H2S, CO2, chlorides, and acidic environments (NACE MR0175 certified).
✅ ​Machinability: Excellent forgeability and weldability, ideal for CNC precision machining.
✅ ​Extended Lifespan: 3-5x longer service life vs. standard alloys due to fatigue and fretting resistance.

​Applications

• ​Aerospace: Jet engine turbine disks, combustion chambers, rocket thrusters
• ​Oil & Gas: Downhole tools, deep-sea valve stems, LNG pump shafts
• ​Power Generation: Gas turbine blades, nuclear reactor fasteners
• ​Automotive: High-performance racing engine parts, turbochargers
• ​Chemical Processing: Agitator shafts for acidic reactors, high-temperature flangesHigh-Strength, Heat-Resistant Superalloy for Extreme Environments
