Tantalum R05200 & R05400 Round Bars Manufacturer & Exporter

Ratnadeep Steel & Engg. Co. is a trusted manufacturer, exporter, and supplier of Tantalum R05200 and Tantalum R05400 Round Bars known for their exceptional corrosion resistance, high melting point, and excellent performance in extreme chemical and high-temperature environments. Tantalum is a refractory metal widely used in critical and high-purity industrial applications.

Tantalum R05200 Round Bars are commercially pure tantalum with excellent resistance to most acids, including hydrochloric, nitric, and sulfuric acids. With outstanding ductility and formability, R05200 round bars are extensively used in chemical processing equipment, heat exchangers, reactors, and corrosion-resistant linings.

Tantalum R05400 Round Bars are high-purity tantalum alloys containing tungsten, offering improved high-temperature strength and enhanced creep resistance compared to R05200. These round bars are ideal for demanding applications such as aerospace components, furnace hardware, nuclear systems, and advanced chemical processing environments.
