Request For Our Latest Prices On Stainless Steel 409 Fasteners in Da Nang, Vietnam!
Poang Fasteners stands out as a top manufacturer and supplier of Stainless Steel 409 Fasteners in Da Nang, Vietnam. We provide affordable and durable solutions for industries that need moderate corrosion resistance and outstanding high-temperature performance. SS 409 is a ferritic stainless steel mainly crafted for automotive exhaust systems, offering solid oxidation and corrosion resistance in mildly corrosive environments. Our SS 409 Fasteners are produced following ASTM, DIN, and ISO standards, guaranteeing quality, precision, and durability. These fasteners find their place in automotive applications, heat exchangers, power generation, and industrial equipment where strength and thermal stability are crucial.
Stainless Steel 409 Fasteners are made up of 10.5–11.75% chromium, 0.08% carbon, along with trace amounts of manganese, silicon, titanium, and nitrogen. The addition of titanium helps stabilize the alloy, enhancing its weldability and resistance to intergranular corrosion. SS 409 boasts a tensile strength ranging from 380–450 MPa and a yield strength of about 170–240 MPa, along with good oxidation resistance up to 675°C. While it may not match the corrosion resistance of austenitic grades, SS 409 Fasteners excel in thermal stability, wear resistance, and cost-effectiveness. Their ferritic structure ensures reliable dimensional stability, making them ideal for high-temperature and moderately corrosive settings.
