Stainless Steel 317/317L Forged Fittings are high-alloy austenitic grades enriched with molybdenum, which gives them remarkable resistance to pitting, crevice corrosion, and chemical attacks. Typically, their composition includes chromium (18–20%), nickel (11–15%), and molybdenum (3–4%), with 317L having controlled carbon content to enhance weldability. These fittings boast impressive tensile and yield strength, good elongation, and excellent toughness, even at high temperatures. Their mechanical properties make them perfect for aggressive environments where superior strength, formability, and resistance to oxidation and scaling are essential.
