Gangsteel's 316Ti SA240 Type 316Ti excels in power fab.
316Ti's properties shine in power generation.
In boiler tubes (A213 TP316Ti, 1-5mm wall), 316Ti withstands 700°C steam with <0.05 mm/year oxidation, per A240 tests. Example: U.S. plant used 316Ti for 20% longer service.
For turbine blades (A479 Type 316Ti), 316Ti resists creep at 600°C with elongation 40%, compliant with SA240. Example: European facility fitted 316Ti, reducing failures 25%.
In flue gas ducts, 316Ti sheets (1.8mm) endure acidic gases at 200°C without IGC, under ASME SA240. Example: Australian power station extended life 30%.
For condenser tubes (A249 TP316Ti), 316Ti resists pitting in cooling water (PREN 23-28). Example: U.S. nuclear plant used 316Ti for 15 years without corrosion.
