Andre Stainless stands out as a top manufacturer and supplier of Stainless Steel 446 Bolts in Pulau Ujong, Singapore, providing dependable fastening solutions for environments that face high temperatures and corrosive conditions. With a solid reputation for crafting heat-resistant alloys, Andre Stainless produces SS 446 bolts that excel in extreme situations, including furnaces, exhaust systems, and chemical processing units. The company is dedicated to precision engineering and rigorous quality control, ensuring that their bolts offer durability, structural integrity, and resistance to oxidation and scaling. This makes them perfect for both industrial and marine applications in challenging service environments.
Stainless Steel 446 Bolts are crafted from a high-chromium ferritic stainless steel alloy, featuring about 23–27% chromium and low carbon content. These bolts are known for their outstanding resistance to high-temperature oxidation and corrosion, especially in sulfur-rich atmospheres. On the mechanical side, they boast a tensile strength of around 485 MPa and a yield strength of about 275 MPa, along with moderate ductility and good toughness at elevated temperatures. Their ability to maintain structural stability and withstand thermal fatigue makes them ideal for long-term use in high-heat industrial settings.
