EN ISO CODE:
Superior Alloy designed for Die Rebuilding & Surfacing for extra tough Hot & Cold Working Tools.
A superior alloy 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. The deposited weld metal is tough for hot or cold work tooling. It is free from cracks, porosities and any other surface defects.
LoTherme-9580 is suitable for hot & cold work trimmers, shear, blanking & forming dies, punches, coining dies, header dies, forging dies, hot working tools & guides, H-11 dies, etc. It has exceptional wear characteristics at high temperature, ideal for press dies and impactor dies. Machinability is limited to grinding.
As Welded : 52-57 RC
SR 560 C for one hour : 51-56 RC
Re-dry the electrodes at 250-300 C for 1 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 400 C and maintain this while welding, with short arc, along with peening after every pass is necessary. After welding, cool in still air up to 200 C. Then charge these large dies into a furnace to hold at 560 C and temper for one hour per inch thickness of job and then slow cool to room temperature for machining.
