Aditya Stainless, a reputable manufacturer and supplier located in Kolkata, India, specializes in providing durable and budget-friendly Stainless Steel 409 Fasteners tailored for automotive, industrial, and structural applications. Crafted from ferritic stainless steel, these fasteners boast impressive oxidation resistance, moderate corrosion resistance, and solid mechanical strength, particularly in high-temperature settings. Produced under strict quality control and industry standards, Aditya Stainless ensures that their precision-engineered 409 fasteners meet the demands of various applications. With extensive use in exhaust systems, thermal equipment, and construction, these fasteners offer an economical and dependable solution for both domestic and international clients across multiple sectors.
Stainless Steel 409 Fasteners mainly consist of chromium (10.5–11.75%), along with carbon (≤0.08%), titanium (≤0.75%), and trace amounts of nickel and nitrogen. This well-balanced composition enhances oxidation resistance, weldability, and high-temperature strength while keeping costs down. Their mechanical properties feature a tensile strength ranging from 380–550 MPa, yield strength around 170–240 MPa, and elongation of 20–30%. While they may not be as corrosion-resistant as the 304 or 316 grades, 409 fasteners provide reliable thermal performance, moderate strength, and structural stability, making them perfect for applications exposed to heat and mildly corrosive conditions.
