Rankin Industries has introduced NON-MAG 1™, a metal cored sub arc wire containing Nickel, Chrome, Manganese, and Silicon that's microstructure is fully austenitic and non-magnetic and is designed to band non-magnetic down hole tools and equipment.

Applications for NON-MAG 1™ include down hole survey equipment that is non-magnetic such as drill collars, and directional drill heads where they house sensitive electronic equipment to find locations or mapping.
