Stainless Steel 440B Bolts are crafted from a high-carbon martensitic stainless steel that contains 16–18% chromium, along with moderate amounts of manganese and silicon, plus trace elements of sulfur and phosphorus. This unique composition enables the alloy to achieve remarkable hardness after undergoing heat treatment. In terms of mechanical properties, 440B offers high tensile and yield strength, excellent wear resistance, and impressive edge retention. While its corrosion resistance is somewhat limited compared to austenitic grades, its outstanding durability under friction, stress, and abrasive conditions makes 440B Bolts perfect for heavy-duty, high-strength fastening tasks.
