317L STEEL PLATES/COILS
Alloy 317LMN (UNS S31726) is an austenitic chromium-nickel-molybdenum stainless steel with corrosion resistance superior to 316L and 317L. The higher molybdenum content, combined with an addition of nitrogen, provides the alloy with its enhanced corrosion resistance, especially in acidic chloride containing service.
Characteristics:1.High temperature alloy with high temperature strength.2. Good resistance to oxidation and corrosion resistance performance.3. Good fatigue performance, the fracture toughness, plastic.Organizational characteristics:High temperature alloy for a single (austenitic) matrix organization, in all kinds of temperature has good stability and reliability of the organization to use.High temperature alloy quality requirements:External quality: external contour shape, size accuracy, the surface defect cleaning method.Internal quality: chemical composition, structure, mechanical and physical and chemical properties.Mechanical properties: room temperature and high temperature tensile properties and impact toughness, high temperature lasting several creep properties, hardness and high weeks and weeks, creep, fatigue performance under the mutual action of fatigue and the mechanical properties, thermal and corrosion resistance to oxidation.STAINLESS STEEL 317L SHEET

317LMN(S31726) | 80 | 550 | 35 | 240 | 40 | 223 | 96 | not required |
Grade | Reasons for choosing grade 904L |
316L | A lower cost alternative, but with much lower corrosion resistance. |
6Mo | A higher resistance to pitting and crevice corrosion is needed. |
2205 | A very similar corrosion resistance, with the 2205 having higher mechanical strength, and at a lower cost to 904L. (2205 not suitable for temperatures above 300°C.) |
Super duplex | Higher corrosion resistance is needed, together with a higher strength than 904L. |
