The loudest, most expressive strings ever created providing increased output, frequency response, and strength. M-Steel, short for Maraging Steel, is a superalloy used in high stress applications for the aerospace and defense industries. The wound strings are comprised of a patented Super Cobalt alloy wrapped around a Maraging steel hex core wire, producing a richer and fuller tone with powerful low end response. M-Steel plain strings are comprised of a specially tempered steel for maximum fatigue resistance. A patented winding of steel around the ball end of the plain strings reduces slippage, breakage and stays in tune better than conventional plain strings. Gauges .010, .013, .017, .026, .036, .046}
Ernie Ball Regular Slinky M-Steel 10-46
M-Steel wound strings feature black coated ball ends made from high quality brass wire rod to our exacting specifications
M-Steel Slinky strings are precision wound with a patented iron-cobalt alloy wire containing even more cobalt than Cobalt Slinkys providing maximum output and clarity.
The core is made from "M-Steel" which stands for maraging steel. This defense grade superalloy provides enhanced low end, improved tuning stability, and increased fatigue strength.
