Our Stainless Steel 446 bolts are made from a high-chromium ferritic stainless steel alloy, containing around 23–27% chromium, along with elements like molybdenum and silicon to boost heat and corrosion resistance. These bolts are known for their impressive resistance to oxidation and scaling at temperatures reaching up to 1100°C. While they aren’t heat-treatable for extreme hardness, they still provide good mechanical strength and structural stability during thermal cycling. Their magnetic properties and resistance to sulfidation and carburization make them perfect for high-heat applications. Plus, our Stainless Steel 446 bolts meet ASTM and DIN standards, ensuring consistent mechanical performance.
