Stainless Steel 316/316L Buttweld Fittings are molybdenum-containing austenitic stainless steels that provide superior resistance to pitting, crevice corrosion, and general chemical attack. Grade 316L contains less carbon compared to 316, enhancing weldability and minimizing sensitization risk. These fittings generally offer tensile strength approximately 515 MPa and yield strength approximately 205 MPa, in addition to having superior ductility and toughness. Their resistance to chloride environments also places them in suitable applications for marine and saltwater use, with high mechanical properties over a broad temperature range.
