Its corrosion resistant properties provide multiple benefits for end users including longer equipment life, lower operating downtime and increased operating temperatures. Tantalum is an excellent material of choice for the fabrication of piping systems, heat exchangers, columns, reactors, bayonet heaters, crucibles, furnace liners and thermocouple protection sheaths; it is also a good choice for the repair of glass lined containers. ATI tantalum products meet the ASTM B521 and B708 standard specifications for tantalum and tantalum alloy seamless and welded tubes as well as plate, sheet and strip.
