OA Mn14

OA Mn14

Austenitic deposit with strain hardening properties and no limits in the number of layers. The deposit is non magnetic and can not be flame cut.

OA 350

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.

OA 400

OA 400

Due to the high resistance to cracking and toughness, all weld metal requires no buffer layer. Suited for wear parts subject to heavy pressure, 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 usually already achieved in the first layer.

OA 550-VW

OA 550-VW

Very good abrasion resistance in combination with impact even at higher temperatures up to 550ºC. To much layers should be avoided, preheat is necessary to avoid cracking. A buffer layer with OA 4370 or OA MnCr is recommended in case of sensible basematerial or old layers. Weldable without protective gas. 

OA 54 L

OA 54 L

Can be welded crack free by preheating approxiamately 450°C and keep that also as interpass temperature. Slowly cooling down, for example in an oven.

OA 55 TC

OA 55 TC

Very good wear resistance against abrasion combined with impact. The deposit gives already a very good hardness in the second layer thanks to the Titanium carbides. The choice for the buffer layer is depending on the base metal and not always necessary. 

OA 56 Nb

OA 56 Nb

Very good wear resistance against abrasion combined with impact. The deposit gives already a very good hardness in the first layer thank to the Nb carbides. The choice for the buffer layer is depending on the base metal and not always necessary. If applied correctly the hardfacing layer wil not show any cracks.

OA 612

OA 612

This alloy offers very good resistance against general abrasion and heavy shock, all weld metal requires no buffer layer except on materials considered critical or in case of old hardfacing layers. In this Situation OA 4370, ER 100 S1 or OA MnCr is recommended.Suited for wear parts subject to strong impact, abrasion and shock. In critical cases the interpass temperature should be kept at 270ºC for the best results. The weld metal is only machinable by grinding.Weldable without gas (open arc). (Also weldable under M21 mixed gas)

OA 57-62 Nb

OA 57-62 Nb

Due to the high Niobium content this alloy offers very good resistance against abrasion by minerals, all weld metal requires no buffer layer except on materials considered critical or old hardsurfacing layers. In this Situation OA 4370, ER 100 SG  is recommended. Suited for wear parts subject to heavy impact and shock. In critical cases such as cement rollers the interpass temperature should be kept at 270ºC for the best results. The weld metal is only machinable by grinding.

OA 58

OA 58

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.
