Stainless Steel 316 Bolts are crafted from an austenitic stainless steel alloy that contains about 16–18% chromium, 10–14% nickel, and 2–3% molybdenum. The inclusion of molybdenum greatly boosts resistance to pitting and crevice corrosion, particularly in environments rich in chlorides. On the mechanical side, SS 316 bolts provide impressive tensile and yield strength, along with excellent ductility and high toughness. They maintain their mechanical stability across a wide temperature range and show good fatigue resistance, making them ideal for heavy-duty and corrosive service conditions.
