Stock program: 3 – 38 mm OD / 1/8” – 1.1/2” OD
Specification: ASTM A 213/ASME SA 213 / EN 10216-5/EN 10305/ISO 15156-3 / NACE MR0175/PED 97/23 EC
Maximum service temperature: 430°C / 800°F
317L is an molybdenum-bearing austenitic stainless steel, with greatly increased resistance to chemical attack as composed to the conventional chromium-nickel austenitic steel tubes as 304L & 316L. the addition of molybdenum gives alloy 317L tubing improved resistance to chloride and other halides. Due to its low carbon content the 317L tubing can be welded without risk of sanitization due to inter granular corrosion that can result from chromium carbide precipitation in the grain boundaries. 317L is non magnetic in the annealed condition, but may become slightly magnetic as result of welding.
Characteristics:
Resistance to sensitization during welding
Higher creeps, stress-to-rapture and tensile strength at elevated temperatures
Corrosion and pitting resistance
Resistance in acidic and hand water areas
Market applications:
Offshore, oil & gas
Chemical
Hydraulic
Shipbuilding
Refining
Pulp and paper
