ASTM A358 Pipe

ASME SA358 Gr 304 Class 1 Seamless Pipe and A358 Material Supplier in India

ASTM A358 represents a standard grade specifying the characteristics of austenitic electric fusion-welded stainless steel. The ASTM A358 Pipe is meticulously crafted with a remarkable composition of chromium and nickel. The intrinsic content of these pipes provides heightened resistance to corrosive and oxidative elements. ASTM A358 EFW Pipes are categorized into classes 1, 2, 3, 4, and 5. Manufactured through the passage of high-speed beams that convert kinetic energy into heat, these pipes are well-suited for high-temperature applications and are available in various shapes and dimensions. The ASME SA358 Gr 304 Class 1 Seamless Pipe is designed as a pressurized-vessel grade for use in extremely high temperatures.

These pipes exhibit enhanced strength and feature an 18/8 chromium and nickel composition. This composition empowers the ASTM A358 grade 304 pipe to function effectively in corrosive and reducing environments prevalent in a variety of stress-inducing setups. Known for their robustness, these pipes can be subjected to hot or cold working to achieve desired characteristics.

In contrast, the ASTM A358 TP304L stainless steel pipe is a low carbon variant of the 304 grade, offering immunity to sensitization and facile weldability using standard welding procedures. The pressurized ASME SA358 GR 316 Seamless Pipe boasts a higher content of nickel, chromium, and molybdenum, enabling utilization in environments prone to pitting and crevice corrosion due to contaminant buildup in the system.

SA358 Stainless Welded Pipes present a cost-effective alternative to seamless pipes, although with lower strength. They are available in sizes above 24 inches or larger. For any additional inquiries or questions regarding our products, feel free to reach out to us for more information.
