Stainless Steel 304/304L Forged Fittings are incredibly versatile and resistant to corrosion, making them a go-to choice in various industrial piping systems. Their impressive strength, durability, and ease of fabrication are just a few reasons why they’re so popular. Trusted suppliers like Devang Fittings in Kolkata, India, manufacture these fittings, which are perfect for applications that demand robust mechanical properties, high resistance to corrosion, and excellent weldability. The 304L variant, with its lower carbon content, significantly reduces the risk of carbide precipitation during welding, making it especially suitable for high-purity or welded systems.

Grade 304/304L stainless steel is an austenitic alloy that typically contains around 18–20% chromium and 8–12% nickel. The 304L version has a maximum carbon content of 0.03%, compared to 0.08% in 304, which enhances its resistance to intergranular corrosion after welding. These alloys boast tensile strengths of about 485 MPa and yield strengths close to 170 MPa, all while maintaining excellent ductility, toughness, and corrosion resistance across various environments, including both oxidizing and mildly reducing conditions.
