LoTherme-359
AWS: SFA
EN ISO CODE:
LoTherme-359 is a smooth-running, basic-coated electrode deposits low-alloy filler metal. The electrode is designed for superior weldability, producing minimal spatter, stable arc, good wetting characteristics and excellent slag removal. This alloy offers high impact resistance and moderate abrasion resistance. Its ferrite-Bainite microstructure promotes excellent crack resistance.
Applications : LoTherme-359 is ideally suited for welding Mn-Mo-Ni alloys to themselves, to other metals and for surfacing steel with Mn-Mo-Ni deposit. Applications in this category include rams, sow blocks, die holders, die shanks, hammers bases and columns. It is also Utilized in steel mills and in maintenance shops for welding general machine parts such as steel gears, large arbors and shafts.
TYPICAL MECHANICAL PROPERTIES OF ALL WELD METAL :
| Properties | UTS (MPa) | Charpy ‘V’ Notch (J) | %EI (L=4d) | As Welded Hardness (HRC) |
| Typical | 1080 | 55 | 17% | 17-23 |
WELDING TECHNIQUES:
Re-dry the electrode at 250°C for 01 hour before use. Use low current, short arc and stringer beads. Wherever possible weld in flat position.
