Key Features & Advantages
  • Exceptional High-Temperature Strength: Maintains excellent mechanical properties up to 700°C (1292°F), making it ideal for aerospace engine and gas turbine components.
  • Outstanding Corrosion Resistance: Superior resistance to oxidation, pitting, crevice corrosion, and stress-corrosion cracking in harsh environments including sour gas (NACE MR0175 compliant).
  • Precipitation Hardenable: Achieves ultra-high strength through controlled heat treatment (solution annealing + double aging) without compromising ductility.
  • Excellent Weldability: Resistant to post-weld cracking and strain-age cracking, suitable for complex fabrication and repair welding.
  • Multi-Grade Compliance: Certified to meet international standards across USA, Germany, China, France, UK, and Japan, simplifying global procurement.
  • Cryogenic to High-Temperature Range: Reliable performance from -253°C (-423°F) cryogenic conditions up to 700°C continuous service.
Typical Applications
  • Aerospace: Jet engine discs, shafts, casings, blades, seals, and afterburner components.
  • Oil & Gas: Downhole tubing, hangers, valve bodies, wellhead components, subsea equipment.
  • Power Generation: Gas turbine hot-section components, steam turbine bolting, heat exchanger tubing.
  • Nuclear: Reactor core components, control rod drive mechanisms, pressure vessel internals.
  • Chemical Processing: Heat exchangers, reaction vessels, piping systems handling corrosive media.
  • Cryogenic: Liquid oxygen and liquid hydrogen storage tanks, pipes, and structural components.
