E309L-16 - Stainless Steel Welding Electrode - 14" x 1 8" 4 4 LB

E309L-16 STAINLESS STEEL ELECTRODE AWS A5.4 Welding Positions: All, except vertical down AC & DC+ (reverse polarity) INTRODUCTION: Rutile-basic coated, high-alloy stick electrode. Designed for joining stainless steel to mild or low alloy steel. Can be welded in any position except vertical down. Joint welding on heat-resistant CrNi steels. Self-removing slag, very low spatter tendency. For dissimilar joints and buffer layers. Excellent ignition and re-ignition characteristics. Maximum operating temperature 300 C APPLICATIONS: Austenite-ferrite joints (dissimilar), cladding, corrosion-resistant layers on non-alloyed construction steels, buffer layers. Joining stainless steel to mild or low alloy steel WELDING PARAMETERS: Polarity Current (Amps) 3/32 (2.4 mm) 1/8 (3.2 mm) 5/32 (4.0 mm) DC+ 40-70 60-100 90-140 AC 40-70 60-100 90-140 CHEMICAL COMPOSITION (%): Chemical Composition C Mn Si S P Requirement ?0.15 0.50 ~ 2.50 ?1.00 ?0.030 ?0.040 Typical test result 0.055 1.45 0.70 0.009 0.021 Chemical Composition Cr Ni Mo Cu Requirement 22.0 ~ 25.0 12.0 ~ 14.0 ?0.75 ?0.75 Typical test result 24.25 12.75 0.035 0.10 MECHANICAL PROPERTIES OF DEPOSITED METAL: Test Item Rm(N/mm2) A (%) Requirement ?550 ?25 Typical test result 595 40 The above parameters are for reference purpose and depend on diverse factors.
