By utilizing cutting-edge manufacturing techniques and rigorous quality control, Aditya Stainless has built a solid reputation in the stainless steel sector, catering to clients both in India and around the world with competitive pricing and prompt delivery.
Stainless Steel 446 Nuts are primarily made up of chromium (23–27%), iron, along with trace elements like manganese, silicon, and carbon. This type of ferritic stainless steel is celebrated for its outstanding resistance to oxidation and sulfidation, especially at high temperatures. In terms of mechanical properties, these nuts have a tensile strength of about 485 MPa, a yield strength of roughly 275 MPa, and demonstrate good elongation and hardness. They also offer excellent thermal stability, moderate strength, and remarkable corrosion resistance in oxidizing environments, making them perfect for furnace components and high-temperature chemical applications.
