Stainless Steel 440B Stud Bolts are made from a martensitic stainless steel alloy with 16–18% chromium and 0.75–0.95% carbon. With this composition, the alloy can be heat-treated to increase hardness and wear resistance. Mechanical properties consist of high tensile strength, satisfactory fatigue resistance, and moderate corrosion resistance in less aggressive conditions. With a high melting point and superior edge holding, these bolts are best suited for applications involving mechanical toughness and durability under thermal and mechanical loads.
