Stainless steel pipes usually consist of iron, chromium (a minimum of 10.5%), nickel, molybdenum, and trace elements which promote corrosion resistance and strength. Mechanical properties differ with grade but typically consist of tensile strength between 485 and 620 MPa and yield strength between 170 and 310 MPa. Elongation prior to fracture can be in the range of 40%, with high ductility and toughness even at subambient temperatures. The strength, corrosion resistance, and formability combined make stainless steel pipes suitable for rigorous industrial applications with durability and performance over long service lives.

Stainless steel pipes are extensively applied in many industries because they are corrosion resistant, strong, and hygienic in nature. They are utilized in construction for structural skeleton and piping systems. The oil & gas and petrochemical industries utilize them to transport corrosive fluids. They provide contamination-free handling in the food processing and pharmaceutical industries because of their non-reactive surfaces. They are also employed in water treatment facilities, automotive parts, heat exchangers, and nautical applications. Due to their capability to work at high pressure and temperatures, they are an essential option for critical systems in modern day infrastructure and manufacturing processes.
