Description
Cold Rolled ASTM B862 Grade 2 Titanium Heat Exchanger Tube - Seamless Corrosion Resistant UNS R50400
ASTM B862 Grade 2 Cold Rolled Titanium Heat Exchanger Seamless Tube

ASTM B862 Grade 2 titanium tube is a commercially pure titanium tubular product designed for corrosion-resistant heat-transfer service, particularly in environments where seawater, chlorides, brine, wet chlorine, organic acids, or oxidizing media make stainless steel or copper-nickel unreliable. Grade 2 / UNS R50400 provides an optimal balance of corrosion resistance, formability, weldability, and moderate strength, with ASTM minimum tensile strength of 345 MPa, yield strength of 275 MPa, and elongation of 20% in the annealed condition.

Technical Accuracy Note: ASTM B862 is formally for titanium and titanium alloy welded pipe, while heat exchanger tubes are more directly covered by ASTM B338, and seamless pipe by ASTM B861. ASTM B338 specifically covers seamless and welded titanium tubes for condensers and heat exchangers, and seamless tubes are manufactured from hollow billet by cold reducing or cold drawing.

Our Advantages
Buyer Concern Our Practical Control
"Is ASTM B862 correct for a seamless heat exchanger tube?" We prevent standard mismatch at quotation stage. ASTM B862 is for welded titanium pipe; if the buyer needs true seamless heat-exchanger tubing, we quote ASTM B338 or ASTM B861 together with Grade 2 / UNS R50400, wall basis, test method, and inspection scope.
"Will Grade 2 titanium survive chloride or seawater service?" Grade 2 titanium is selected for chloride-containing environments, seawater cooling, brines, wet chlorine, and oxidizing media. It has strong resistance to general corrosion, pitting, crevice corrosion, erosion corrosion, and chloride stress corrosion cracking.
"Can the tube be expanded into tube sheets without leakage risk?" We control OD, wall thickness, annealing condition, surface cleanliness, and straightness. For tube-sheet expansion, a wall reduction of about 10% is used as a practical engineering reference for pull-out strength.

Application Field

Seawater-cooled shell-and-tube condenser tubing for coastal power plants.

Grade 2 titanium tube is used as condenser tube material where high-chloride seawater attacks stainless steel or copper alloy tubes. Its corrosion resistance allows stable heat-transfer operation, reduced leakage risk, and longer service intervals in cooling-water systems.

Chemical Composition

Reference grades commonly used in ASTM titanium tube specifications. Values are weight percent; titanium is balance unless otherwise stated.
