UNS R05400 Forgings

R05400, B365

Tantalum UNS R05400 Forgings are components manufactured from alloy containing chromium and nickel with addition of copper to achieve precipitation hardening. Tantalum UNS R05400 Forgings are used in the oil and gas, nuclear and aerospace industries where a combination of high strength, corrosion resistance and a generally low but acceptable degree of toughness is required. TorqBolt is an eminent Tantalum UNS R05400 Forgings supplier in India.
