Benefits

Versatile
Tough
Low moisture absorption
Fast welding speeds
Insensitive to base material composition
Meets NACE TM0177 and TM0284 standards
Low diffusible hydrogen

The OK 48.00 E7018 low hydrogen welding electrodes are a reliable and versatile choice for welding a variety of carbon steels. They deposit a tough, crack-resistant weld metal with low moisture absorption and fast welding speeds. The electrodes are insensitive to base material composition and meet the requirements of the NACE TM0177 and TM0284 standards for welding in corrosive environments. They also have low diffusible hydrogen, which helps to reduce the risk of cold cracking.

Features
Reliable and versatile: OK 48.00 is a general purpose electrode that can be used for welding a variety of carbon steels, including carbon manganese steels and fine-grained carbon manganese steels with elevated yield strength.
Tough and crack-resistant welds: OK 48.00 deposits a tough, crack-resistant weld metal that is ideal for applications where strength and durability are critical.
Low moisture absorption: The coating on OK 48.00 is of the low moisture absorption type, which helps to prevent the formation of weld defects.
Fast welding speeds: OK 48.00 can be welded in all positions, including the vertical-up position, and it offers fast welding speeds.
Insensitive to base material composition: OK 48.00 is insensitive to the composition of the base material within fairly wide limits, making it a versatile choice for a variety of welding applications.
Meets NACE TM0177 and TM0284 standards: OK 48.00 has been tested and meets the requirements of the NACE TM0177 and TM0284 standards, which means it is suitable for welding in corrosive environments.
Low diffusible hydrogen: OK 48.00 has low diffusible hydrogen, which helps to reduce the risk of cold cracking.
