ESAB 6881 ALLMAT is an acid-rutile, high-alloyed electrode which deposits a ferritic-austenitic duplex weld metal with approx. 40% ferrite. Resistant to stress corrosion and highly insensitive to dilution. Good scaling resistance up to 1150 degrees C. OK 68.81 is used for joining dissimilar steels, steels with reduced weldability and buffer layers prior to hardfacing. Applications: rolls, forging dies, hot-work tools, dies for plastics etc. Welding current DC+, AC, OCV 60 Volts Classifications Approvals Typical all weld metal composition, % Typical mech. properties all weld metal EN 14700 E Fe11 EN ISO 3581-A E 29 9 R 3 2 SFA/AWS A5.4 E312-17 Werkstoff Nr. 1.4337 Seproz UNA 272580 C 0, 115 Si 0, 75 Mn 0, 75 Cr 29 Ni 9, 75 Mo 0, 5 Cu 0, 3 P 0, 030 S 0, 020 Yield stress, MPa 610 Tensile strength, MPa 790 Elongation, % 22 Elongation, % 22 Ferrite content FN 35 65 Weld metal hardness, a w 220-240 HV Machinability Fair Charpy V Test temps, C Impact values, J +20 30 Redrying temperature,
