Industry Sector |
Typical Applications |
|
Nuclear Industry |
Fuel cladding tubes, control rod guide tubes, core structural components (low neutron absorption cross-section) |
|
Chemical Processing |
Reactors, heat exchangers, storage tanks, and piping for highly corrosive media like concentrated hydrochloric acid, sulfuric acid, hydrofluoric acid |
|
Aerospace |
Structural components, parts resistant to high temperature and pressure |
|
Medical |
Dental materials, implantable devices (biocompatibility) |
|
Marine / Deep-Sea Exploration |
Desalination equipment, flanges, bolts for subsea pipelines resisting chloride ion corrosion |
|
Others |
Electronic vacuum equipment, pharmaceutical equipment, corrosion-resistant valves |
Advantages & Technical Characteristics
Excellent Corrosion Resistance: Corrosion rate in 50% boiling sulfuric acid is < 0.01 mm/a, approximately one-thousandth that of 316L stainless steel. Demonstrates superior resistance to strong acids, alkalis, and fluorides.
Low Neutron Absorption Cross-Section: Suitable for nuclear reactor core components, significantly reducing neutron capture within the reactor and improving fuel utilization.
High Melting Point & Elevated Temperature Strength: Melting point ~1855°C, boiling point 4409°C. Can operate short-term above 400°C with good oxidation resistance.
Good Mechanical Strength & Ductility: Tensile strength 380-615 MPa, elongation 16-20%. Maintains certain toughness at high temperatures.
Biocompatibility: Complies with health standards like FDA, widely used in dentistry and implantable medical devices.
Workability: Can be hot-rolled, hot-forged, and cold-worked. Welding requires preheating and post-weld heat treatment to prevent cracking.
