OK Tubrodur 15.73
FCAW
Type Metal-cored
OK Tubrodur 15.73 is a versatile, flux-cored, hardfacing wire which deposits a martensitic 13Cr alloy steel deposit, especially suitable for applications involving wear at elevated temperatures. These will include shafts, valve seats, rolls and other parts subjected to wear, and/or corrosion at high temperatures. Gas mix 80% Ar+20% CO2 is recommended.
