Stainless Steel 316 Hydraulic Fittings are crafted from molybdenum-bearing austenitic stainless steel, featuring a composition of Chromium (16–18%), Nickel (10–14%), and Molybdenum (2–3%). This unique alloy offers exceptional corrosion resistance, particularly against chlorides, acidic fluids, and harsh industrial chemicals. The material boasts impressive mechanical properties, including high tensile strength (around 515 MPa), yield strength (minimum 205 MPa), and excellent elongation (~40%), ensuring reliable performance even under high-pressure conditions. Additionally, Stainless Steel 316 maintains its toughness across a wide range of temperatures, making it an ideal choice for hydraulic systems that face temperature variations and challenging environmental conditions.
