Haynes 25 (L605) is a cobalt-based superalloy known for high strength and corrosion resistance at extreme temperatures. Parag Metal supplies Haynes 25 sheets in India, offering material that meets key specifications, such as AMS 5537. It can handle temperatures up to 2150°F and remains durable even in harsh situations such as moist chlorine or hydrochloric acid. With a minimum yield strength of 45,000 psi at room temperature (as per AMS 5759), this alloy is built for durability. These UNS r30605 sheets are non-magnetic and maintain their properties at high heat, making them ideal for both aerospace and industrial use.
This alloy is widely utilized in gas turbine engine combustion chambers, afterburners, springs and heart valves. It operates well under stress and heat, making it excellent for components subject to extreme circumstances. Haynes 25 sheet has proven to be reliable in jet engine turbine blades and combustion liners. It is also used in high-temperature furnace components, where long-term strength and resistance to oxidation are critical.
