Dean Markley Blue Steel Cryogenic Activated Acoustic Guitar Strings

Dean Markley’s world-famous Blue Steel acoustic strings are engineered for players who demand brilliant tone, unmatched longevity, and consistency. These 92/8 phosphor bronze strings undergo a unique cryogenic treatment — flash-frozen to -320ºF with liquid nitrogen — to tighten the molecular structure of the metal. The result is a smoother surface, longer life, and a sound that’s both warm and sparkling, with powerful projection and clarity that holds strong through countless performances.

Blue Steel strings are celebrated for their vibrant tonal response and resistance to corrosion, delivering up to three times the lifespan of standard strings. Whether you’re a studio professional or a gigging musician, these strings maintain their fresh, balanced tone longer, giving you confidence and consistency every time you play.
