OK 48.00 is a general purpose electrode designed for welding carbon steel, carbon manganese steel, and fine-grained carbon manganese steel with high crack resistance. OK 48.00 produces a tough, crack-resistant metal surface. The coating has low moisture absorption. High welding speed in 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 constructions where it is not possible to avoid stresses.

Features
H4 R - approved hydrogen level.
- Low diffusible hydrogen reducing the risk of cold cracking
- Very low moisture absorption of the coating
- High efficiency increasing productivity
- Excellent weldability in vertical up position
- Good appearance of the welded seam
