SS 304 Fasteners - Neonox
SS 304 Fasteners with High Strength & Corrosion Resistance
SS 304 Fasteners offered by Neonox are widely preferred for industrial applications due to their excellent versatility, durability, and corrosion resistance. Manufactured from high-quality stainless steel grades such as 304, 304L, and 304H, these fasteners provide reliable performance in demanding environments.
These fasteners are available in various forms, including bolts, screws, nuts, and washers, to meet diverse application needs. Made from an austenitic stainless steel alloy containing approximately 18% chromium and 8% nickel, SS 304 fasteners offer superior resistance to corrosion, oxidation, and staining. Their excellent mechanical properties and ease of fabrication make them an ideal choice for a wide range of industrial and structural applications.

Stainless Steel 304L Fasteners offered by Neonox are similar to SS 304 fasteners but contain lower carbon content, making them ideal for welding applications. Their reduced carbon composition minimizes the risk of sensitization and intergranular corrosion during welding, ensuring enhanced durability and performance. These fasteners are widely used in industries such as chemical processing, food processing, and pharmaceutical equipment manufacturing.
On the other hand, SS 304H Fasteners are specifically designed for high-temperature applications. With a higher carbon content, they provide improved strength and excellent resistance to elevated temperatures. These fasteners are commonly used in applications such as gas turbines, boiler systems, and heat exchangers, where reliable performance under extreme conditions is essential.
