ASTM A358 EFW 317 / 317L Pipes are high-performance austenitic stainless steel pipes manufactured using the Electric Fusion Welding (EFW) process. These pipes contain higher molybdenum content compared to 316 grade, providing superior resistance to pitting and crevice corrosion in aggressive chemical environments.
Grade 317 offers enhanced corrosion resistance and mechanical strength while 317L (low carbon version) improves weldability and reduces the risk of intergranular corrosion during fabrication.
