Mitchell Stainless, a trusted manufacturer and supplier in Hamilton, New Zealand, provides high-quality Stainless Steel 304 and 304L forged fittings designed for reliable, corrosion-resistant piping systems. 304/304L is an austenitic stainless steel offering excellent corrosion resistance, durability, and ease of fabrication, making it suitable for chemical, food, beverage, and general industrial applications. Mitchell Stainless ensures each forged fitting meets strict quality standards, providing smooth finishes, precise dimensions, and consistent mechanical performance. These fittings are engineered to deliver secure, long-lasting connections in piping systems requiring resistance to corrosion, moderate temperatures, and mechanical stress.
Stainless Steel 304/304L forged fittings are composed primarily of iron, with 18–20% chromium, 8–10% nickel, and small amounts of carbon, manganese, and silicon. The 304L variant has lower carbon content to improve weldability and minimize carbide precipitation during welding. Chromium provides excellent corrosion and oxidation resistance, while nickel enhances toughness and mechanical stability. This composition ensures 304/304L forged fittings maintain durability, structural integrity, and reliable performance in moderate industrial, chemical, and food-processing environments.
