10 Typical Mechanical Typical Undiluted Type Properties Weld Metal Analysis Specifications As Welded % wt Arcaloy 317L AWS A5.4 Tensile Strength Carbon 0.03 ASME SFA 5.4 80,000 to 90,000 psi Manganese 1.7 Class (552 to 621 MPa) Silicon 0.5 E317/317L-15 & -16 % Elongation in 2" (51 mm) Chromium 19.0 MIL-E-22200/2, 35 to 45 Nickel 12.7 MIL-317-15 & -16 Molybdenum 3.5 FN 9 Arcaloy 317L electrodes are recommended for welding type 317 & 317L with a maximum 0.04% carbon in the weld deposit. The higher molybdenum content of these electrodes as compared to Arcaloy type 316L further reduces the susceptibility of pitting corrosion. Arcaloy 347 AWS A5.4 Tensile Strength Carbon 0.04 ASME SFA 5.4 85,000 to 95,000 psi Manganese 1.8 Class E347-15 & -16 (586 to 655 MPa) Silicon 0.6 MIL-E-22200/2, % Elongation in 2" (51 mm) Chromium 19.5 MIL-E347-15 & -16 35 to 45 Nickel 9.5 Niobium 0.8 FN 8 Arcaloy 347 electrodes are especially designed for welding types 347 and 321 alloys. Type 347 alloy was developed to prevent carbide precipitation. For service temperataures above 750°F (400°C) use Arcaloy 308H. Continued on next page... Recommended Welding Parameters page 14
