SS 317/317L Plates represent a significant upgrade in corrosion performance over the standard 316 series, primarily due to their increased Molybdenum content (3.0% to 4.0%). This high-alloy composition provides exceptional resistance to chemical attack, particularly in environments containing sulfuric, acetic, formic, and tartaric acids. The 317L variant is a low-carbon version (0.03% max) that provides immunity to sensitization during welding, ensuring that the plates maintain their structural integrity and superior corrosion resistance in the heat-affected zones of large-scale fabrications.

Manufactured in strict accordance with ASTM A240 and ASME SA240, these plates are the industry standard for the most demanding "severe service" applications, such as pulp and paper manufacturing, flue gas desulfurization (FGD) systems, and chemical processing plants. SS 317/317L plates offer higher tensile and creep strength at elevated temperatures compared to conventional stainless steels. Their ability to resist pitting and crevice corrosion in high-chloride process streams makes them an indispensable solution for offshore oil and gas equipment and advanced pharmaceutical reactors where standard grades might fail.

SS 317/ 317L Plates Features

» Advanced Acid Resistance: Significantly higher resistance to sulfuric, acetic, formic, and citric acids compared to standard 316L due to increased molybdenum levels.
» Low Carbon Immunity: The 317L variant (0.03% max carbon) prevents sensitization and intergranular corrosion, ensuring structural integrity in welded assemblies.
» Enhanced Pitting Protection: Offers a higher Pitting Resistance Equivalent Number (PREN) than Grade 316, making it ideal for high-chloride process environments.
» High-Temperature Durability: Provides superior creep, stress-to-rupture, and tensile strength at elevated temperatures, suitable for heavy industrial thermal processing.
» Pulp and Paper Specialist: Specifically designed to withstand the aggressive chemical bleaching agents used in paper mills and flue gas desulfurization (FGD) systems.
» Excellent Ductility: Despite its high alloy content, it maintains excellent formability and can be easily cold-worked into various industrial components.
» Cryogenic Stability: Retains its toughness and non-magnetic properties at sub-zero temperatures, suitable for specialized chemical storage.
» Surface Finish Options: Available in a variety of finishes, including 2B for industrial tanks and No.4/Satin for pharmaceutical and clean-room applications.
