Special AlloysSheet/Plate
Description (English)
Grade 2 is the default choice for chemical processing, marine hardware, heat exchangers, medical implants, and any application where corrosion resistance and biocompatibility are paramount. For higher strength requirements, Grade 5 (Ti-6Al-4V) or Grade 23 (Ti-6Al-4V ELI) are typically specified.
