Harsh Metalloys is a prominent manufacturer and supplier of SS 409 Bolts, based in Mumbai, India. These bolts are crafted from stainless steel 409, a ferritic alloy known for its excellent corrosion resistance, high-temperature strength, and cost-effectiveness. SS 409 is often used in applications requiring moderate corrosion protection, good formability, and weldability. Our SS 409 bolts are manufactured to meet international quality standards and are ideal for use in automotive, exhaust systems, structural assemblies, and industrial applications. With a focus on precision, durability, and timely delivery, Harsh Metalloys is your trusted partner for stainless steel fasteners.
SS 409 Bolts are composed of 10.5–11.75% chromium with a low carbon content (≤0.08%) and may include stabilizing elements like titanium. This composition provides excellent oxidation resistance, moderate corrosion resistance, and improved weldability. The bolts exhibit tensile strength of approximately 380–450 MPa and yield strength around 170 MPa. SS 409 offers good ductility and is non-hardenable by heat treatment. It performs well in moderately corrosive environments and retains strength at elevated temperatures, making it suitable for structural and thermal applications where cost and performance are key considerations.
