ASTM B521 Tantalum Seamless Tubes Tantalum is a shiny, silvery metal which is soft when is pure. It is almost immune to chemical attack at temperatures below 150 C. Tantalum is virtually resistant to corrosion due to an oxide film on its surface. Application of Tantalum Seamless Tube Tantalum resist corrosion and is almost impervious to chemical attack, for this reason it has been employed in chemical industry, e.g. Heat exchanger in boilers where strong acids are vaporized Chemical Reactors Chemical Pipelines Tantalum Tube Grade Scope: R05200 unalloyed tantalum R05400 unalloyed tantalum R05255 tantalum alloy, 90% tantalum, 10% tungsten R05240 tantalum alloy, 60% tantalum, 40% niobium Specification Standard of Tantalum and Tantalum Alloys Seamless and Welded Tubes ASTM B521 Except Tantalum Tubes and Pipes, BJMK still specialize in manufacture, supply and export Tantalum Plate, Sheet, Strip according to ASTM B708 and Tantalum Rod and Wire according to ASTM B 365, and other custom made Tantalum Fittings & Components.Exotic Metals Free Sample website:http://www.mk-titanium.com/exotic-metals/
