They pride themselves on precision engineering and durability, offering a wide variety of bolts, nuts, screws, and washers that are built to perform in tough conditions. Their Stainless Steel 409 Fasteners are well-known for their impressive corrosion resistance, heat tolerance, and structural integrity. Mbemba Stainless guarantees that every product adheres to international standards, catering to industries like automotive, construction, and manufacturing with dependable fastening solutions that promise long-lasting and efficient assembly performance.
Stainless Steel 409 Fasteners are mainly made up of iron, along with 10.5–11.75% chromium, and small amounts of titanium, nickel, and carbon. This ferritic stainless steel grade provides moderate corrosion resistance, particularly against exhaust gases and environmental elements. In terms of mechanics, it boasts good tensile strength, moderate hardness, and excellent oxidation resistance up to 675°C. The alloy is also known for its good ductility and weldability, making it a great choice for forming and fabrication. Thanks to its balanced composition, Stainless Steel 409 offers a cost-effective solution that performs reliably in moderate corrosion and high-temperature settings.
