Stainless Steel 301 Tubing is an austenitic 17-19% chromium and 6-8% nickel alloy with minor contents of manganese, silicon, and carbon. The composition is superior for toughness, corrosion resistance, and durability under harsh conditions. The alloy has superior formability and ductility while providing superior strength. Mechanical properties comprise tensile strength of 520–720 MPa, yield strength of 205 MPa, and elongation of approximately 40%, which enables it to function well under high-stress applications. Its strength-to-oxidation resistance balance renders it extremely desirable for challenging industrial and engineering use.
