Applications of SS 304 Fasteners
SS 304 fasteners are in high demand due to their versatility and can be utilized in various applications. In construction, they are used in structures, roofing, and cladding systems because of their strength and corrosion resistance. In the automobile industry, 304 stainless steel fasteners are essential for parts such as exhaust systems and undercarriages where heat and rust resistance are critical. In the aerospace industry, ASME B 304 Stainless Steel Fasteners join critical aircraft components, ensuring reliability under great stress. In the marine industry, these fasteners are used in boats and ships, withstanding saltwater environments.
At Sumit Impex, we use advanced manufacturing techniques such as cold forging, hot forging, and precision machining to produce fasteners that meet the highest quality and performance standards. Our products comply with internationally recognized standards, including ASTM (American Society for Testing and Materials), ASME (American Society of Mechanical Engineers), DIN (Deutsches Institut für Normung), and EN (European Norms).
To ensure top-notch quality, every batch of our Stainless Steel 304 Fasteners is tested in our well-equipped laboratory. This involves tensile testing for measuring material strength, impact testing for performance under high loads, hardness testing for measuring hardness, and intergranular corrosion testing (IGC) for evaluating corrosion resistance. Positive Material Identification Testing is also conducted to confirm material composition.
Our Stainless Steel 304 Fasteners come in various sizes, shapes, and finishes, including bright annealed, powder coating, anodizing, and custom painting to enhance functionality and appearance.
The current price for Stainless Steel 304 Fasteners in India ranges from ₹200 to ₹350 per kg, depending on the product specifications and requirements. At Sumit Impex, we are dedicated to providing high-quality fasteners at competitive prices, ensuring excellent performance and value for all your fastening needs.
