Bohler Product Codes:
- 17683 - 1.0mm 18kg
- 17684 - 1.2mm 18kg
Features and Applications:
- A low-alloy, copper-coated solid MIG wire with additions of Nickel, Chromium and Molybdenum, designed for welding of high-strength steels with minimum yield strength of 890 MPa and minimum tensile strength of 940 MPa.
- Exhibits excellent mechanical properties and good toughness characteristics at low temperatures.
- 120S-G can be used on high-strength parent steel grades such as API 5AL80, HY100, HY80, S890QL and BS 4360 Gr55F and is also suitable for Hystal 77, Navy Q1, Naxtra 70, QT 445, RQT 701 and Weldox 900. Mechanical properties are greatly influenced by preheat, interpass temperature, and post weld heat treatment.
- Suitable for use on high-strength steels, in applications such as earth moving equipment, cranes and industrial truck fabrication, and on high-strength pressure vessels and some heat treatable steels.
