Samia Pipes and Tubes, based in Tunis, Tunisia, is a trusted manufacturer and supplier of high-quality industrial pipes and tubes. Among our premium offerings are Stainless Steel 420 Pipes, renowned for their excellent hardness, corrosion resistance, and wear properties. Precision-engineered to meet demanding industrial standards, these pipes deliver reliability and long-term performance. At Samia Pipes and Tubes, we focus on providing more than just materials—we offer solutions that help industries operate efficiently and safely. Each Stainless Steel 420 Pipe reflects our commitment to quality, durability, and engineering excellence.
Stainless Steel 420 Pipes are part of the martensitic stainless steel family, primarily composed of 12–14% chromium with low carbon content. They provide high hardness after heat treatment, with a tensile strength typically between 450–700 MPa and yield strength of 250–500 MPa, depending on tempering. With a density of around 7.75 g/cm³, these pipes combine mechanical strength with good corrosion resistance in mild environments. Their ability to maintain sharp edges, resist wear, and endure moderate chemical exposure makes Stainless Steel 420 Pipes a versatile choice for industrial applications.
