LoTherme OA-457S

An 18-8-5 Stainless Steel OA wire for Joining & Surfacing

Characteristics

LoTherme OA-457S wire deposits 18Cr - 8Ni - 5Mn type work hardening, radiographic quality weld metal, suitable for welding manganese steel to carbon steel and for build up applications involving severe impact and compressive loads. It is used for welding 13% Mn steel, high carbon steels and other steels which are difficult to weld with unalloyed or low alloyed electrodes.

Applications

LoTherme OA-457S wire is suitable for welding of railway points & crossings, armour plate, dredging equipments, hammers, jaw & cone crusher, roll crushers, roll crusher, various steel mill applications like; coupling boxes, hook liners, ladle repairs, joining of wear plates, etc. This wire is also used as buffer layer before hand surfacing.
