Esab OK 48.08 Low Alloy Low Hydrogen Stick Electrodes - E7018-G H4R Carton - 4.0 x 450mm 3/4 VP
Benefits
Achieve tough, dependable welds on carbon steels, carbon manganese steels, and fine-grained carbon manganese steels
Minimise the risk of hydrogen cracking, a critical factor in offshore applications
Ensure excellent low-temperature toughness for reliable performance in cold environments
Meet NACE standards for resistance to HIC and SSC for offshore construction
Tough, Dependable Welds on Carbon Steels
The 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.
Features
Excellent 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 welds
HIC 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.
