Good Corrosion Resistance ASME SB338 GR7 UNS R52400 Ti Alloy Tube
We are one of the biggest manufactures of stainless steel & duplex steel & alloy steel tubes and pipes in China. With development more than 20 years, we have accumulated a great many clients all around the world and YUHONG products also won the great praise among the customers.
ASME SB338 is the standard specification for seamless and welded titanium and titanium alloy tubes or tubing which are intended for surface condensers, evaporators, and heat exchangers. It is identical with ASTM B338 except for some minor difference in product marking. There are 28 grades of titanium and titanium alloys for tubing purpose, among which Titanium Grade 2, Grade 7 and Grade 12 are most often seen in tubing applications.
Titanium Grade 7 (UNS R52400) has similar physical and mechanical properties to Grade 2. It has excellent welding and fabrication properties and is extremely resistant to corrosion, especially acids, due to the addition of palladium.
