Due tothe high alloying the flux isintended for plate thickness upto approximately 20mm injoining applications.OK Flux 10.80 is used ingeneral construction, pressurevessel industries and others. Itis appreciated for surface buildupjobs such as the repair ofdiesel engine pistons, becausehardness of the weld metal isincreased due to the highalloying.C Si Mn Cr Ni Mo OtherWith OK Autrod12.10 0.07 0.7 1.412.20 0.09 0.6 1.7Typical weld metal mechanical properties, DC+ReL / Rp0.2(MPa)Rm(MPa)A4 / A5(%)CVN(J at °C)With OK Autrod +20 0 -18 -2912.10 410 520 28 110 80 40 AW12.20 440 550 29 90 70 40 AW12.10 370 500 30 100 70 45 SR12.20 400 540 30 80 60 40 SRAW/SRRemarksFor more information view the Product Data Sheets or contact ESAB.45
