Classification : AWS : E 7018-1 , BIS : EB5629H3JX
Characteristics : This Is a medium heavy coated, all positions hydrogen controlled Iron powder electrode for low temperature applications. Weld produced Is of radiographic quality. The weld metals Is of high x-ray soundness, providing good mechanical properties and excellent impact strength at – 50°C High weld recovery over 110%.
- This Is ideal for welding of fine grained carbon manganese steel and medium tensile steel.
- Steel sensitive to hydrogen embrittlement.
- Pressure vessels, boilers, mounded bullets heavy fabrication work and for pipelines subjected to low temperature applications.
Weld Metal Properties (%) :
C = 0.09 Max Mn = 1.60 Max
All Weld Mechanical Properties :
