ASTM A403 stainless steel flanges pipe fittings, specifically the 90-degree tee in 304L and S316L, are engineered for durability and reliability in various industrial applications. These fittings offer excellent corrosion resistance and high tensile strength, making them ideal for high-pressure environments.
ASTM A403 fittings are manufactured using cold-forming processes, ensuring precision and consistency in dimensions. The addition of elements like chromium and nickel in the composition enhances resistance to harsh conditions, including chloride-induced corrosion.
The A403 90-degree tee is designed to meet industry standards for seamless and welded pipe fittings, providing long-lasting performance with minimal maintenance.
