309 Stainless Steel Tube
309 stainless steel tube 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 Steel Tube
309 stainless steel tube has excellent high-temperature resistance and can remain stable and durable even at high temperatures, which makes it widely used in industrial furnaces and boilers. What makes 309 stainless steel tube so resistant to high temperatures? 309 stainless steel tube 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. The tube is also composed of 12% nickel, which improves its toughness and ductility at low temperatures.
