Stainless Steel Bolts from Andre Stainless come in grades such as 304, 316, and duplex stainless steel. Their typical composition includes 18–20% chromium, 8–14% nickel, and 2–3% molybdenum (in 316 grade) for improved corrosion resistance. These bolts have tensile strength ranging from 515–700 MPa and yield strength between 205–480 MPa, depending on the grade and processing. They offer strong resistance to corrosion, oxidation, and high temperatures. The mechanical stability and hardness of these bolts make them well-suited for load-bearing and vibration-prone environments, providing reliable fastening in challenging or outdoor settings.
