Stainless Steel 409 Stud Bolts consist mainly of iron with 10.5–11.75% chromium, minor amounts of nickel, carbon (≤0.08%), manganese, silicon, and trace constituents such as titanium or niobium for stabilization. This ferritic stainless steel is highly resistant to oxidation and has moderate corrosion resistance. Its mechanical properties include tensile strength of about 380–620 MPa, yield strength of 170–280 MPa, and elongation of about 20%. All these features make SS 409 stud bolts appropriate for applications with moderate stresses that need heat resistance and endurance, especially where relatively low-cost stainless performance is vital.

Stainless Steel 409 Stud Bolts find extensive application in automobile exhaust systems, particularly in mufflers and manifolds, because of their superior high temperature and exhaust gas corrosion resistance. They are used in industrial processes in heat exchangers, furnaces, and gas turbines where thermal stability is required. Due to their low cost and corrosion resistance, they are also used in construction, petrochemical plants, and power plants. Further, these bolts are applied in pressure vessels and flanged joints, providing consistent fastening in static and dynamic load conditions. SS 409 stud bolts are particularly preferred where the strength and cost effectiveness are matched.
We prioritize quality and rigorously test all our products before shipping. These include hardness testing, chemical analysis (spectroanalysis), PMI testing, micro-macro testing, pitting resistance testing, fire testing, and intergranular corrosion testing. We provide complete documentation, such as commercial invoices with HS codes, packaging lists with loads, labels and numbers, and departure certificates. In addition, we provide third-party review certifications to ensure 100% customer satisfaction.
