Esab OK 48.08 Low Alloy Low Hydrogen Stick Electrodes - E7018-G H4R Carton - 4.0 x 450mm 3/4 VP
BenefitsAchieve tough, dependable welds on carbon steels, carbon manganese steels, and fine-grained carbon manganese steelsMinimise the risk of hydrogen cracking, a critical factor in offshore applicationsEnsure excellent low-temperature toughness for reliable performance in cold environmentsMeet NACE standards for resistance to HIC and SSC for offshore constructionTough, Dependable Welds on Carbon SteelsThe ESAB OK 48.08 is a premium quality, low-hydrogen stick electrode designed for welding carbon steels, carbon manganese steels, and fine-grained carbon manganese steels with elevated yield strength. This electrode is particularly well-suited for offshore construction applications where exceptional toughness and reliability are demanded.The ESAB OK 48.08 features a basic covering that produces a low moisture absorption coating. This low moisture absorption design minimizes the risk of hydrogen cracking, a critical factor in offshore applications. Additionally, the OK 48.08 produces weld metal with a diffusible hydrogen content of less than 4ml per 100 grams, further reducing the risk of cracking.FeaturesExcellent low-temperature toughness: The OK 48.08 delivers exceptional impact toughness at temperatures as low as -50C, thanks to an alloyed weld metal containing approximately 0.9% nickel. This makes it ideal for critical applications in cold environments.Reduced hydrogen cracking: The low moisture absorption coating and low diffusible hydrogen content minimise the risk of hydrogen cracking, a common problem in offshore weldsHIC and SSC compliance: The ESAB OK 48.08 is compliant with NACE TM0284 for resistance to Hydrogen Induced Cracking (HIC) and NACE TM0177 for resistance to Sulfide Stress Cracking (SSC), making it a reliable choice for demanding offshore environments.Ordering Part No. Description 48085042V0 OK 48.08 5.0x450mm 3/4 VP - 4 Packs 48083232G0 OK 48.08 3.2x350mm 1/2 VP - 6 Packs 48082532G0 OK 48.08 2.5x350mm 1/2 VP - 6 Packs 48084042V0 OK 48.08 4.0x450mm 3/4 VP - 4 Packs 48083242G0 OK 48.08 3.2x450mm 1/2 VP - 6 Packs ApplicationsOffshore Construction: Ideal for demanding applications like offshore platforms and pipelinesShipbuilding: Suitable for welding various steel components in shipbuildingPressure Vessel Fabrication: Used in the construction of pressure vessels and tanksStructural Steel: Applicable to structural steel fabrication and repairsGeneral Fabrication: Versatile for a wide range of general fabrication projectsSpecifications Specifications Classifications SFA/AWS A5.5 : E7018-G H4REN ISO 2560-A : E 46 5 1Ni B 32 H5 Approvals ABS : 3Y H5CE : EN 13479DB : 10.039.31DNV-GL : 4 Y40H5LR : 4Y40 H5UKCA : EN 13479VdTV : 05778 Welding Current AC, DC+(-) Diffusible Hydrogen < 4.0 ml/100g Alloy Type Low alloyed (0.9 % Ni) Coating Type Basic covering Min AC OCV 65 Typical Tensile Properties Condition Yield Strength Tensile Strength Elongation AWS As welded (3G, V-UP) 530 MPa 610 MPa - ISO As Welded 540 MPa 630 MPa 26 % PWHT1 hour(s) 620 C 480 MPa 550 MPa 26 % Typical Charpy V-Notch Properties Condition Testing Temperature Impact Value AWS As welded (3G, V-UP) -50 C 55 J As welded (3G, V-UP) -60 C 50 J ISO PWHT1 hour(s) 620 C -46 C 105 J As Welded -50 C 85 J As Welded -60 C 65 J Typical Weld Metal Analysis % C Mn Si Ni Cr Mo 0.06 1.2 0.35 0.95 0.02 0.001 Deposition Data Diameter Current Voltage Efficiency (%) Fusion time per electrode at 90% I max Deposition Rate
