Headquartered in Pulau Ujong, Singapore, Andre Stainless is a prominent manufacturer, supplier, and exporter of high-performance stainless steel products. Among our products is the Stainless Steel 409 Fasteners, which boasts exceptional mechanical strength, oxidation resistance, and high-temperature performance. These fasteners are made for demanding use in automotive, aerospace, and chemical processing industries and provide consistent, dependable performance. In an array of sizes, shapes, and dimensions, our 409 fasteners are precision-engineered to the highest industry standards. Committed to quality and innovation, Andre Stainless continues to respond to various industrial requirements with distinction.
Stainless Steel 409 Fasteners consist of a ferritic stainless steel alloy containing mainly 11.75% chromium, approximately 0.08% carbon, and trace amounts of manganese, silicon, and sulfur. This alloy gives moderate corrosion resistance, outstanding oxidation resistance, and good formability. While less corrosion-resistant than austenitic grades, 409 is more stable at high temperature and is cheaper. The alloy possesses medium tensile strength, good weldability, and endures thermal cycling, and is recommended for automotive and industrial applications. Due to its economic benefits and mechanical balance, it is a suitable choice for high–volume, performance-oriented applications.

SS 409 Fasteners are extensively used in the automotive and industrial industries for their oxidation resistance, thermal resistance, and strength. Typical uses are in automotive exhaust systems, mufflers, and engine parts where the material resists high temperatures and gases. They are also utilized in chemical processing facilities, heat exchangers, and structural assemblies needing good strength in mildly corrosive conditions. The cost-effectiveness and formability of 409 stainless steel make it a convenient option for mass production. These fasteners are also ideal for application in marine and construction environments, providing durable performance in moderately aggressive environments.
