Stainless Steel 904L Bars and Rods
Stainless Steel 904L Bars and Rods
Stainless Steel 904L bars and rods are high-performance materials renowned for their superior corrosion resistance, durability, and exceptional strength. These bars and rods are made from non-stabilized austenitic stainless steel formulated with significant additions of nickel, chromium, molybdenum, and copper. Known for its robustness in severe conditions, it is perfect for use in environments with high levels of acidity and chloride. Its impeccable weldability and formability make it ideal for various industrial applications including oil & gas, chemical processing, and marine equipment.
The cross-sections utilized in industrial applications are round bars and rods. But they have a cylindrical length cross-section, and the diameter varies according on the industrial use. Depending on the type of use, different industries offer different bars and rods. Both hot-rolled and cold-rolled stainless steel bars and rods are available; however, the cold-rolled bars have more accurate specifications and are ideal for bracing, motors, and other applications. The construction industry makes extensive use of hot-rolled bars and rods due to their various size and other factors.
