Case hardening, High & Medium Tensile Steels

Case Hardening Steels

AISI 8620: Low Nickel-Chrome-Moly Steel, with core strengths of 700-1100 Mpa, in small to medium sections, and a typical case hardness up to Rc62, when carburised, hardened and tempered. End use: Light/medium stressed wear resistant parts.

En36A: Nickel-Chrome Steel, with core strengths of 850-1200 Mpa, in small to fairly large sections, and a typical case hardness up to Rc62, when carburised, hardened and tempered. End use: Medium/highly stressed wear resistant parts.

17CrNiMo6: Chrome-Nickel-Moly Steel, with core strengths of 900-1300 Mpa, in small to fairly large sections, and a typical case hardness up to Rc62, carburised, hardened and tempered. End use: Highly stressed wear resistant parts.

En39B: Nickel-Chrome-Moly Steel, with core strengths of 1000-1400 Mpa, in small to very large sections, and a typical case hardness up to Rc62, carburised, H&T. End use: Heavily stressed large wear resistant parts.

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.

Medium Tensile Steels – Bright & Black

AISI 1045: Medium Carbon Steel, with good strength, toughness and resistance to wear plus good machining and welding properties. Will flame or induction harden, with a typical case hardness up to Rc58. End use: Medium stressed parts.
