Haynes 25/L605 Round Bars

What is Haynes 25/L605 Round Bar ?

Haynes 25 round bar, also called Alloy L605 or UNS R30605 round bar, is a strong cobalt-based alloy. It contains more chromium, nickel, and molybdenum, with less carbon. This gives bars excellent resistance to oxidation up to 1800°F. It also handles hot forming well between 1900°F and 2300°F. Parag Metal is a leading haynes 25 bars supplier in India, providing reliable products that meet global quality standards. The alloy has a density of 9.13 g/cm³ and a melting point of 1382°C, making it ideal for high-temperature uses.
