AWS: SFA

EN ISO CODE:

LoTherme-9580M have balanced chemical composition contain with Cr - Ni - Mo and W. It is designed for surfacing / cladding of a new die and re-building of worn-out hot forging dies. The consumables has very good welder appeal and easy slag detachability. It is free from cracks, porosities and any other surface defects.

Approvals

Weld Metal Hardness (on 3 layers) :

As Welded : 48-53 HRC

Welding Techniques :

Re-dry the electrodes at 250-300oC for One hour. When welding hardenable steels of large thickness, adequate care for preheating, slow cooling & post weld heat treatment are recommended for best results. Pre-heat heavy thickness jobs up to 400oC and maintain this while welding, with short arc, along with peening after every pass is necessary. After welding, cool in still air up to 200oC.

Electrical Characteristics : DC (+)
