MILD STEELSTICK ELECTRODES (SMAW)OK 48.00esab.com/fillermetalsA reliable, general purpose electrode for manual metal arc welding of carbon steels, carbon manganese steels and fine-grained carbon manganese steels with elevated yield strength. OK 48.00 deposits a tough, crack-resistant weld metal. The coating is of the low moisture absorption type. High welding speed in the vertical-up position. OK 48.00 is insensitive to the composition of the base material within fairly wide limits. The electrode can be used for welding structures where difficult stress conditions cannot be avoided. Tested according to NACE TM0177 and TM0284. Diffusible Hydrogen tested in various conditions show values below 3 ml/100g.SpecificationsClassificationsSFA/AWS A5.1 : E7018 H4 R EN ISO 2560-A : E 42 4 B 42 H5 ApprovalsABS : 3Y H5 BV : 3Y H5 CE : EN 13479 DB : 10.039.12 DNV-GL : 3 YH5 LR : 3Y H5 PRS : 3Y H5 RINA : 3Y H5 RS : 3Y H5 VdTÜV : 00690 NAKS/HAKC : 2.5 - 5.0 mm IndustryCivil Construction Energy Industrial and General Fabrication Light Fabrication Marine and Offshore Welding CurrentDC+(-)Diffusible Hydrogen< 4.0 ml/100g (< 3 for most of the batches)Alloy TypeCarbon ManganeseCoating TypeBasic coveringTypical Tensile PropertiesConditionYield StrengthTensile StrengthElongationISOAs Welded475 MPa565 MPa29 %Typical Charpy V-Notch PropertiesConditionTesting TemperatureImpact ValueAWSAs Welded-30 °C130 JISOAs Welded-40 °C115 JAs Welded-30 °C130 JTypical Weld Metal Analysis %CMnSi0.061.10.5
