Alloys 309H and 309S Stainless Steel Pipe are austenitic chromium-nickel stainless steel steels that will be commonly used for much higher temperature applications. Because of their higher chromium and also nickel content, Alloys 309H and also 309S Stainless Steel Pipe are high rust resistant, have excellent resistance to oxidation, and also outstanding heat resistance when offering good energy at room and increased temperature ranges. The only major difference between 309H with 309S Stainless steel tube is the carbon content.

Applications:

309H with 309S SS Piping are utilized primarily for their high-temperature oxidation resilience, outstanding high temperatures energy, together with their resistance to creep deformation and also environment attack. A few examples include, but are not restricted to:

• Heating components

• Aircraft and also jet engine parts

• Heat ex-changers

• Carburizing annealing products

• Sulfite liquor managing machine

• Kiln liners

• Boiler baffles

• Refinery and also chemical processing machines

• Auto exhaust components
