These Stainless Steel 446 Pipes are mainly made of iron with a high chromium content (around 23–27%) and very little carbon, along with trace amounts of molybdenum and titanium to boost corrosion resistance and stability. In terms of mechanics, these pipes provide moderate tensile and yield strength, good ductility, and outstanding resistance to high-temperature scaling and oxidation. Their ferritic microstructure contributes to dimensional stability, magnetic properties, and long-lasting durability under thermal stress, making them suitable for both fluid transport and structural uses in challenging environments.
