Spark Steel offers high-quality Stainless Steel 317L Pipes (WNR 1.4438), engineered for exceptional performance in high-corrosion environments across industries such as oil and gas, chemical processing, marine, and power generation. Available in seamless, ERW, EFW, and welded forms, these pipes come in various shapes (round, square, rectangular) and schedules (including SCH-10, SCH-40, SCH-80, and SCH-160). Grade 317L features a low carbon content for improved resistance against intergranular corrosion without requiring post-weld annealing, alongside a robust chemical composition of 18.0–20.0% chromium, 11.0–15.0% nickel, and 3.0–4.0% molybdenum. Backed by comprehensive testing procedures—such as hydrostatic, ultrasonic, and impact testing—Spark Steel ensures premium durability and adherence to international ASTM standards.
