Stainless Steel 443 tubing is a ferritic stainless steel alloy mainly made up of chromium and iron, with small amounts of titanium and niobium added to boost stability and corrosion resistance. With about 21–23% chromium content, this tubing provides excellent resistance to oxidation, scaling, and stress corrosion cracking caused by chlorides. It boasts impressive mechanical properties, including tensile strength, thermal stability, and durability at high temperatures. The ferritic structure gives it magnetic properties and ensures dimensional stability under thermal stress, making Stainless Steel 443 tubing a great choice for high-temperature and aggressive environments.
