ASME SB338 Grade 7 refers to a specific standard and material specification for Titanium Alloy (Ti-0.2Pd). This material is engineered for applications demanding exceptional corrosion resistance and high strength in challenging environments.
The GR7 designation indicates a titanium alloy containing Titanium (Ti) as the base metal with 0.12% to 0.25% Palladium (Pd) as the alloying element. The palladium addition provides superior corrosion resistance, particularly in acidic environments and seawater, resulting in reduced maintenance requirements and extended service life compared to stainless steel or carbon steel alternatives.
Chemical Composition
Titanium Grade 7 (Ti-0.2Pd) primarily consists of titanium with 0.12-0.25% palladium, offering enhanced corrosion resistance in aggressive environments including seawater, chemicals, and heat exchangers
Titanium (Ti) provides an excellent strength-to-weight ratio, outstanding corrosion resistance, and high-temperature performance
Palladium (Pd) improves resistance to general corrosion, particularly in acidic environments
Mechanical Properties
Tensile Strength: 550 to 750 MPa (80-110 ksi)
Yield Strength: 275 to 450 MPa (40-65 ksi), ensuring reliable performance under pressure
Elongation: 15-20%, demonstrating good ductility
Applications
Heat Exchangers: Ideal for environments with high corrosion potential including desalination plants, chemical processing industries, and offshore oil and gas platforms
Marine and Offshore Applications: Superior saltwater corrosion resistance makes it perfect for marine environments
Petrochemical and Chemical Industries: Excellent performance in acidic and corrosive environments
