443 Stainless Steel Iron, chromium (about 18–23%), and a small amount of carbon make up the majority of tubing, with titanium and niobium serving as stabilising elements. It provides improved resistance to heat fatigue, oxidation, and corrosion. Its mechanical properties include good elongation (~30%), yield strength (~280 MPa), and tensile strength (~450 MPa). Due to its strong weldability and Brinell Hardness of about 180 HB, SS 443 tubing is a reliable substitute for austenitic grades in a variety of structural and industrial applications.
