Titanium Grade 2 Pipes & Tubes

Commercially Pure (CP) Titanium - The "Workhorse" of the industrial titanium industry, known for its high corrosion resistance and ductility.

Titanium Grade 2 Overview

Titanium Grade 2 (UNS R50400) is the most widely used grade of commercially pure titanium. It offers an excellent balance of moderate strength and reasonable ductility. Grade 2 titanium is extremely resistant to corrosion in highly oxidizing and mildly reducing environments, including chlorides. Its corrosion resistance is derived from a stable, protective, and strongly adherent oxide film that forms in the presence of even traces of oxygen. Steel Emporium provides Grade 2 Titanium pipes and tubes that are lightweight yet incredibly durable, making them ideal for marine, chemical, and aerospace applications.

Key Material Advantages

Lightweight Strength

About 45% lighter than steel with comparable strength-to-weight ratio.

Sea-Water Immunity

Virtually immune to corrosion in seawater and salt-spray environments.

Biocompatible

Non-toxic and highly compatible with the human body for medical use.

Frequently Asked Questions

"CP" stands for Commercially Pure. Titanium Grade 2 is unalloyed titanium, meaning it doesn't contain added elements like Aluminum or Vanadium, making it highly corrosion-resistant.

Yes, Grade 2 is readily weldable using standard fusion methods (TIG/MIG), provided that appropriate shielding gas (Argon) is used to prevent contamination by atmospheric gases.

It is superior in terms of corrosion resistance in seawater and chlorides, and it is 45% lighter than stainless steel. However, it is generally more expensive.

No, Titanium is paramagnetic (non-magnetic), which makes it ideal for use in medical MRI equipment and electronic shielding.

The primary standards are ASTM B337 (Seamless and Welded Pipe), ASTM B338 (Condenser and Heat Exchanger Tubes), and ASTM B861/B862.
