corrosion resistant ferritic piping

Introduction Ferritic stainless steel pipes are characterized by good corrosion resistance, magnetic properties, and low thermal expansion. Unlike austenitic or martensitic grades, ferritic stainless steels such as 430, 409, and 444 are used in industrial piping, automotive exhaust systems, and HVAC applications. According to Stainless Steel World, ferritic pipes account for over 20% of automotive and industrial stainless steel usage, favored for cost-effectiveness and durability.   Material Properties Chromium content: 16–18% Carbon content: ≤0.08% Yield strength: 250–350 MPa Tensile strength: 450–600 MPa Standards: ASTM A268, EN 10088-2   Industrial Applications Automotive Exhaust Systems: Ferritic pipes resist high-temperature oxidation Exampl...
