309 Stainless Pipe
309 stainless pipe is resistant to high temperatures due to its high alloy content. It is composed of approximately 23% chromium, which forms a protective layer on the surface of the metal, protecting it from corrosion and high-temperature oxidation.
309 Stainless Pipe
309 stainless pipe is a type of austenitic stainless steel. It is mainly composed of iron, 23% to 26% chromium, and 12% to 15% nickel. 309 stainless pipe has excellent corrosion and oxidation resistance, and can remain unchanged without deformation and cracking even at temperatures up to 2000°F. Due to this property, it is often used to make parts such as heat exchangers, boilers, etc.
