Summary
Documentation
A 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
4 R approved
Low diffusible hydrogen to reduce the risk for cold cracking
Outstanding low moisture pick up
High efficiency bringing productivity
Extremely good weldability in vertical up position
Exceptional weld appearance
