GH4202

Product Size

Φ5-400mm

Applicable Specifications

National Standard (GB), Enterprise Standard

Key Properties

  1. Wide temperature range: maintains performance from -253°C to 800°C. 

  2. Excellent high-temperature strength: e.g., tensile strength ~830 MPa at 700°C. 

  3. Creep and oxidation resistance: creep life >1000 h at 650°C/150 MPa; weight gain only 0.2 mg/cm² in oxidation test at 1000°C. 

  4. Good weldability (usually welded in solution-annealed condition, post-weld heat treatment required for stress relief)

Application Fields

Aviation, Aerospace, Energy, Nuclear Power, Petrochemical/Oil gas
