What is 19MnCr5?
19MnCr5 (1.3523) is a manganese-chromium case-hardening steel from the EN 10084 family, similar to 17MnCr5 but with slightly modified hardenability for carburized bearing rings and rollers. It is used where a hard, wear-resistant case must sit on a tough core, and is supplied as bar, tube and forging stock in conditions from +U and +AC through +FP, +TH, +S, +H and CH, with core values near 350 MPa yield, 560 MPa tensile and 22% elongation at about 180 HB. It offers no corrosion resistance, is limited to roughly 350 °C service, and can only be welded before carburizing. 17MnCr5 is the nearest alternative. 19MnCr5 has a density of 7.85 g/cm³ (0.284 lb/in³), heavier than 56% of steel grades. It melts at 1,425°C (2,597 °F). 19MnCr5 has a yield strength of 350 MPa (50.8 ksi) and a tensile strength of 560 MPa (81.2 ksi) — weaker than 74% of steel grades. Elongation at break is 22% and the elastic modulus is 210 GPa (30.5 Msi).

Working with 19MnCr5
Is 19MnCr5 easy to machine?
Machine in +TH or +FP (170–217 HB) with carbide inserts and good coolant; leave grinding stock for post-carburizing distortion.
Can 19MnCr5 be welded?
Weldable in the soft state with low-hydrogen consumables and 150–250 °C preheat (CE ≈ 0.55); never weld after carburizing.
Can 19MnCr5 be formed, bent or molded?
Cold heading/extrusion in the +AC spheroidized condition; hot forge 1100–850 °C then slow-cool or anneal to restore machinability.

19MnCr5 — frequently asked
What is 19MnCr5 used for?
19MnCr5 is typically used for carburized bearing rings, rollers and gears. In short: mn-Cr bearing case-hardening steel; tough core, hard case; 17MnCr5 with tuned hardenability.
What is the yield strength of 19MnCr5?
19MnCr5 has a typical yield strength of 350 MPa (50.8 ksi) and a tensile strength of 560 MPa (81.2 ksi) — weaker than 74% of steel grades. Strength varies by condition: see the 8 listed tempers.
Is 19MnCr5 easy to machine?
Reasonably — machinability is rated good (55/100, better than 62% of steel grades). Machine in +TH or +FP (170–217 HB) with carbide inserts and good coolant; leave grinding stock for post-carburizing distortion.
Can 19MnCr5 be welded?
With care — weldability is rated fair (50/100). Weldable in the soft state with low-hydrogen consumables and 150–250 °C preheat (CE ≈ 0.55); never weld after carburizing.
What surface finishes work on 19MnCr5?
Carburize 900–930 °C, oil or gas quench, temper 160–200 °C, then hard-turn or grind; protect with oil, phosphate, black oxide or Zn-Ni plating (bake to avoid H embrittlement).
Can 19MnCr5 be formed, bent or molded?
Cold heading/extrusion in the +AC spheroidized condition; hot forge 1100–850 °C then slow-cool or anneal to restore machinability.
What is the maximum service temperature of 19MnCr5?
19MnCr5 is rated for continuous use to about 350°C (662 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 19MnCr5 +A and 19MnCr5-CH?
+A is the default condition — standard stock condition for bar and tube destined for turning, then carburizing. CH: final in-service condition for bearing rings, rollers and gears: hard wear-resistant case on a tough core. Yield strength is 350 MPa in +A versus 750 MPa in CH.
