Stainless Steel 446 Bolts are crafted from a high-chromium ferritic alloy that offers impressive heat and oxidation resistance. This alloy features elevated levels of chromium, along with small amounts of molybdenum and silicon, which boost its strength and resistance to chemical attacks. These bolts showcase good tensile strength, robust thermal stability, and remarkable resistance to sulfidation and scaling at high temperatures. Although they are less ductile than austenitic grades, SS 446 maintains its structural integrity even under continuous thermal cycling. Its mechanical properties make it perfect for applications that require durability, corrosion resistance, and long-lasting performance in challenging environments.
