Titanium Grade 2 Pipe Supplier in India — R50400

Titanium Grade 2 (UNS R50400) is classified as commercially pure (CP) titanium because it contains a minimum of 99.2% titanium with only minor controlled amounts of oxygen (0.25% max), iron (0.30% max), carbon (0.08% max), nitrogen (0.03% max), and hydrogen (0.015% max). It is the most widely used of all titanium grades, accounting for approximately 50% of total titanium consumption worldwide. The term 'commercially pure' distinguishes it from titanium alloys like Grade 5 (Ti-6Al-4V) that contain significant alloying additions. Grade 2 offers an excellent combination of moderate strength (minimum 345 MPa yield), outstanding corrosion resistance, good formability, and reliable weldability that makes it suitable for the broadest range of industrial applications.

Titanium Grade 1 (R50250) and Grade 2 (R50400) are both commercially pure titanium grades, with the primary difference being oxygen content and consequently mechanical strength. Grade 1 has lower oxygen (0.18% max) giving it lower strength (170 MPa yield) but superior formability and ductility — making it ideal for deep drawing and explosive cladding applications. Grade 2 permits higher oxygen (0.25% max) resulting in higher strength (345 MPa yield) while still maintaining good formability and excellent corrosion resistance. For most industrial piping, heat exchanger, and chemical plant applications, Grade 2 is the standard choice because its higher strength allows thinner wall sections without sacrificing pressure ratings. Grade 1 is preferred only when extreme cold forming is required or when maximum ductility is critical.

Titanium Grade 2 pipe finds extensive application across industries where corrosion resistance to chlorides, seawater, and oxidizing acids is critical. The major consuming industries include: chemical processing (reactors, heat exchangers, piping for chlorine, bleach, chlorides, and oxidizing acids), desalination (MSF and MED evaporator tubes, brine heaters, seawater intake piping), power generation (condenser tubes in coastal thermal plants, FGD systems), offshore oil and gas (seawater cooling systems, fire water systems, subsea piping), chlor-alkali (wet chlorine gas handling, brine piping, anode baskets), pulp and paper (bleach plant piping, ClO2 systems), and marine applications (shipboard seawater systems, submarine cooling). The pharmaceutical and food processing industries also use Grade 2 for its biocompatibility and non-toxic nature.

Creative Metal Industries stocks Titanium Grade 2 seamless pipes per ASTM B861 from 1/2 inch to 10 inches NB in schedules SCH 10S, 20S, 40S, and 80S. Welded pipes per ASTM B862 are available from 2 inches to 10 inches NB in lighter schedules. Condenser and heat exchanger tubes per ASTM B338 are stocked in OD range 6.35mm to 114.3mm with wall thicknesses from BWG 16 to 22. Standard lengths are 4-7 metres random or cut to length as required. All titanium material is supplied in the annealed condition with complete certification including mill test certificate per EN 10204 3.1, chemical analysis, mechanical properties, and positive material identification (PMI) verification.

Titanium Grade 2 has excellent weldability using GTAW (TIG) welding with ERTi-2 filler wire per AWS A5.16. The critical requirement is absolute protection from atmospheric contamination during welding — titanium reacts rapidly with oxygen, nitrogen, and hydrogen above approximately 500°C, causing embrittlement and loss of corrosion resistance. Essential precautions include: trailing shields and backing gas (pure argon, 99.995% minimum purity) to protect the weld and heat-affected zone until cooled below 427°C, thorough cleaning with acetone or MEK before welding, stainless steel wire brushes only (no carbon steel tools), and a clean dedicated welding area. Weld color should be bright silver to light straw — any blue, purple, or grey discoloration indicates contamination and must be removed. No post-weld heat treatment is normally required.

Titanium Grade 2 pipe pricing in India typically ranges from Rs 3,500 to Rs 8,000 per kilogram depending on size, wall thickness, quantity, and current titanium sponge market conditions. Seamless pipes per ASTM B861 command higher prices than welded pipes per ASTM B862 due to more complex manufacturing. Condenser tubes in popular heat exchanger sizes are often available at competitive rates due to volume production. Despite titanium being perceived as expensive, it often proves economical on a lifecycle basis — Grade 2 pipe eliminates the need for corrosion allowance, protective coatings, and premature replacements common with stainless steel in chloride environments.
