TITANIUM GRADE 2 ALLOYS UNS R50400 / DIN 3.7035 / ASTM B265 / AMS 4902

TITANIUM GRADE 2 ALLOYS, also known as UNS R50400 or DIN 3.7035, is a commercially pure titanium alloy (UNS R50400) recognized for its excellent corrosion resistance, lightweight nature, and good weldability. It strikes a balance between moderate strength and high ductility, making it one of the most widely used grades in the titanium family for industrial and chemical processing applications.

This alloy performs exceptionally well in oxidizing, neutral, and mildly reducing environments, such as seawater, various chemical media, and chloride-containing solutions. Titanium Grade 2 is highly resistant to corrosion cracking, pitting, and stress-related deterioration. It maintains its mechanical integrity at temperatures up to 400°C, which makes it suitable for a wide range of operating conditions.

At Plus Metals, we offer Titanium Grade 2 in various forms, including sheets, plates, rods, bars, tubes, and custom-forged components. All products come with material test certifications and meet global quality standards.
