UNS R50400 (Ti Grade 2)
Generic Name & Other Designation
Ti Grade 2, Commercially Pure Ti Grade 2 (CP Ti Grade 2), W.Nr. 3.7035, Ti-Grade 2
Product Overview
UNS R50400 (Titanium Grade 2) is the workhorse of the commercially pure titanium family. Striking a perfect balance between moderate yield strength and high ductility, UNS R50400 exhibits exceptional corrosion resistance in oxidizing media, chloride solutions, and marine environments.
Its low density 4.51g/cm3 allows engineers to drastically reduce system weight while improving component longevity in power plants, seawater desalination facilities, and chemical reactors.
Key Highlights
✅ Optimal Strength-to-Weight Ratio: Provides high structural integrity with half the density of stainless steel.
✅ Passivation Layer Protection: Forms an immediate protective TiO2 oxide layer preventing saltwater attack.
✅ Superior Cold Formability: Highly ductile matrix enables complex deep drawing and cold bending.
✅ Biocompatible & Non-Magnetic: Completely safe for medical implants and sensitive instrument enclosures.
