OA 4370

  • Special flux cored self shielded stainless steel wire for open arc welding
  • The weld beads produced have a self-releasing slag covering that leaves a clean surface
  • Sound deposits are obtained even in the presence of cross draughts
  • Primary choice for cladding and rebuilding application, suitable for joining and cladding
  • Provides maximum productivity for outdoor jobs

OA 350

Due to the high resistance to cracking and toughness, all weld metal requires no buffer layer. Suited for wear parts subject to heavy impact and shock. The interpass temperature should be maximum 250ºC. The weld metal is machinable with carbide tip tools, hardening is possible. The maximum hardness is dependent on the base metal and is usualy already achieved in the first layer.

AA M37-42

Due to the high resistance to cracking and excelent toughness, all weld metal requires no buffer layer except on materials considered critical. Suited for wear parts subject to heavy impact and shock. The interpass temperature should be maximum 250ºC. The weld metal is machinable with carbide tip tools, hardening is possible. The maximum hardness is dependent on the base metal and is achieved already in the first layer.
 

OA 59

Extreme abrasion resistant with reasonable impact properties and temperature resistance up to 300ºC. Due to the combination Cr and Nb carbides the deposit structure contains very fine particles that results in excellent wear resistance against heavy abrasion. Usualy the maximum number of layers is 2 till 3 but when using a special stringer build up technick with release cracks, upto 15 layers is also possible.

OA 61

Very good wear resistance even at higher temperatures. The deposit gives already a very good hardness in the first layer. A buffer layer with OA 4370 or OA MnCr is recommended in case of sensible base material or old layers. Weldable without protective gas.

OA 60 Mo

High wear resistance and austenitic structure deposits. The deposit gives already a very good hardness in the first layer. A buffer layer with OA 4370 or OA MnCr is recommended in case of sensible base
material or old hardface-layers. Weldable without protective gas.

OA 58-66B

High C-, Cr-, B-alloyed flux-cored wire electrode which forms extremely hard carbides for extremely hard deposits on parts subject to excessively heavy abrasive wear weldable with and without protective gas. Verry good wear resistance due to excelent first layer hardness properties. More than 1 or 2 layers should not be deposited. A Buffer layer with OA 4370 or OA MnCr is recommended in case of old layers or critical base metals..

AA BCrMo1V

AA BCrMo1V is a basic cored wire with Excellent weld puddle manipulation. Low spatter loss, easy slag removal. Extremely crack resistant. Suitable for economic welding of CrMoV-steels up to 550 °C. Due to the seamless production process the hydrogen content is below 3ml/100g weld metal even after long storage in unconditioned condition.
