Haynes 25/L605 Pipes

What is Haynes 25/L605 Pipe ?

Haynes 25 / L605 pipes are made from a cobalt-based superalloy known for its high strength and corrosion resistance. The main elements include cobalt, chromium, tungsten, and nickel. These pipes are used in demanding areas like gas turbine engine combustion chambers, afterburners, high-temperature ball bearings, bearing races, springs, and even heart valves. Parag Metals is a trusted haynes 25 pipe supplier in India, known for supplying high quality pipes to a wide range of industries.

Alloy L605 pipe is non-magnetic and can withstand temperatures up to 2150°F. It has yield strength of 45,000 psi at room temperature. This pipe resists oxidation up to 1900°F. It also handles tough environments with exposure to acids like hydrochloric, nitric, and wet chlorine. Its ability to hold up in high heat and harsh chemicals makes it a good choice for critical parts.
