Seller: fillermetalqueen (5,187) 99.9%, Location: Aurora, Illinois, Ships to: US & many other countries, Item: 292301538551 ER70S-7 is a general purpose MIG wire suitable for many carbon steel welding applications but with substantially greater manganese content than ER70S-3 welding alloy. The higher manganese provides slightly better wetting and weld appearance with slightly higher tensile and yield strengths as well. These combined properties permit increased speed when compared to S-3 product. Under equivalent welding conditions, ER70S-7 produces as weld hardness lower than ER70S-6 but higher than ER70S-3. Typical Applications • High tensile strength steels for automobiles • Rolling stock • Electrical appliances • Machinery • Air conditioners • Light gauge steels • Pipes • Steel frames AWS Specification AWS A5.18/A5.18M:2005 AWS Classification ER70S-7 Welding Current for MIG process DCEP (Electrode Positive, Reverse Polarity) Typical Wire Chemistry with Argon + 2% Oxygen C 0.07 - 0.15 Mn 1.50 - 2.00 Si 0.50 - 0.80 P 0.025 S 0.035 Ni 0.15 Cr 0.15 Mo 0.15 V 0.03 Cu 0.50 Typical Wire Chemistry with Argon + 20% CO2 shielding gas C 0.09 Si 0.75 Mn 1.67 P 0.015 S 0.01 Typical Mechanical Properties (As Welded) with Argon + 2% Oxygen shielding gas Yield Strength, ksi 68 Tensile Strength, ksi 82 Elongation%, min 27 Typical Mechanical Properties (As Welded) with Argon + 20% CO2 shielding gas Yield Strength, ksi 70 Tensile Strength, ksi 82 Elongation%, min 29 Welding Positions F,V,OH,H Available Diameters MIG and suggested Operating Range in Amps .023" 35 - 70 .030" 50 - 100 .035" 100 - 150 .045" 150 - 200 1/16" 250 - 500 Available Diameters TIG .035", .045", 1/16", 3/32", 1/8" & 5/32" Condition: New, Brand: Blue Demon, Model: MIG (GMAW/FCAW), MPN: ER70S7-045-44
