Harsh Metalloys is a renowned manufacturer and supplier of premium-quality SS 405 Sheets and Plates based in Mumbai, India. We specialize in offering stainless steel 405 flat products that combine durability, oxidation resistance, and cost-effectiveness. SS 405 is a ferritic stainless steel developed for improved machinability and heat resistance, making it ideal for industrial applications involving moderate corrosion and high-temperature exposure. At Harsh Metalloys, we ensure precise dimensions, uniform surface finishes, and strict quality control, catering to sectors such as automotive, thermal processing, power generation, and fabrication. Our commitment to quality and timely delivery makes us a trusted industry partner.
SS 405 Sheets and Plates are made from ferritic stainless steel containing 11.5–14.5% chromium, with low carbon and small amounts of aluminum to enhance oxidation resistance and stability. The material offers tensile strength between 415–585 MPa and yield strength around 205 MPa, with good elongation and ductility. SS 405 demonstrates excellent resistance to thermal fatigue, scaling, and welding-related distortion. Its ferritic structure makes it suitable for forming and moderate fabrication processes, offering good dimensional stability in high-temperature service conditions. These mechanical properties make SS 405 a reliable and economical choice for heat-resistant applications.
