High Tensile Steels

AISI 4140: Chrome-Moly Steel, with an U.T.S. of 850-1000 Mpa, in sections up to 100mm. Will flame or induction harden - typical case hardness up to Rc54, and will nitride - typical case hardness up to Rc60. End use: Highly stressed parts.

AISI 4340: Nickel-Chrome-Moly Steel, with an U.T.S. of 930-1080 Mpa, in sections up to 100mm. Will flame or induction harden - typical case hardness up to Rc58, and will nitride - typical case hardness up to Rc60. End use: Highly stressed parts.

En25: Nickel-Chrome-Moly Steel, with an U.T.S. of 925-1075 Mpa, in sections up to 250mm. Will flame or induction harden - typical case hardness up to Rc52, and will nitride - typical case hardness up to Rc60. End use: Highly stressed parts.

En26: Nickel-Chrome-Moly Steel, with an U.T.S. of 1000-1150 Mpa, in sections up to 250mm.Will flame or induction harden - typical case hardness up to Rc58, and will nitride - typical case hardness up to Rc60. End use: Very highly stressed parts.
