What is 13MoCrNi42-16-14?
13MoCrNi42-16-14 (1.3555) is a low-carbon Mo-Cr-Ni case-hardening bearing steel, carburized to combine a hard raceway with a tough core for high contact-fatigue duty at elevated temperature. It is used for aerospace and turbine bearing rings and rollers, supplied as annealed or normalized bar and forged rings near 220 HB (860 MPa tensile, 560 MPa yield, 18 % elongation) and available VIM-VAR remelted for cleanliness. High hardenability and roughly 4 % Mo make it effectively non-weldable and hard to machine (score 32); it has no corrosion resistance and the listed maximum service temperature is 200 °C. 13MoCrNi42-16-14 has a density of 7.78 g/cm³ (0.281 lb/in³), lighter than 91% of steel grades. It melts at 1,400°C (2,552 °F). 13MoCrNi42-16-14 has a yield strength of 560 MPa (81.2 ksi) and a tensile strength of 860 MPa (125 ksi) — stronger than 73% of steel grades. Elongation at break is 18% and the elastic modulus is 201 GPa (29.2 Msi).

Working with 13MoCrNi42-16-14
Is 13MoCrNi42-16-14 easy to machine?
Green-machine in the spheroidize-annealed condition with sharp coated carbide and rigid setups; after carburizing and hardening only CBN/diamond grinding, hard turning and lapping are practical.
Can 13MoCrNi42-16-14 be welded?
Not a weldable structural steel — high hardenability and 4% Mo cause hard, crack-prone HAZ; any repair welding needs preheat, matching filler and a full re-heat-treat.
Can 13MoCrNi42-16-14 be formed, bent or molded?
Hot forge 1050–1150 °C with slow controlled cooling and immediate anneal; cold forming is impractical.

13MoCrNi42-16-14 — frequently asked
What is 13MoCrNi42-16-14 used for?
13MoCrNi42-16-14 is typically used for aerospace case-hardened bearings, high-temperature roller bearings and turbine and gearbox bearing rollers. In short: case-hardening bearing steel; tough core, hard case; VIM-VAR grade available.
What is the yield strength of 13MoCrNi42-16-14?
13MoCrNi42-16-14 has a typical yield strength of 560 MPa (81.2 ksi) and a tensile strength of 860 MPa (125 ksi) — stronger than 73% of steel grades. Strength varies by condition: see the 5 listed tempers.
Is 13MoCrNi42-16-14 easy to machine?
Not especially — machinability is rated poor (32/100, worse than 87% of steel grades). Green-machine in the spheroidize-annealed condition with sharp coated carbide and rigid setups; after carburizing and hardening only CBN/diamond grinding, hard turning and lapping are practical.
Can 13MoCrNi42-16-14 be welded?
Not readily — weldability is rated poor (15/100). Not a weldable structural steel — high hardenability and 4% Mo cause hard, crack-prone HAZ; any repair welding needs preheat, matching filler and a full re-heat-treat.
What surface finishes work on 13MoCrNi42-16-14?
Raceways are hard-turned then ground and honed to mirror finish; corrosion protection by oil film, phosphate, black oxide or thin dense chrome — no anodizing.
Can 13MoCrNi42-16-14 be formed, bent or molded?
Hot forge 1050–1150 °C with slow controlled cooling and immediate anneal; cold forming is impractical.
What is the maximum service temperature of 13MoCrNi42-16-14?
13MoCrNi42-16-14 is rated for continuous use to about 200°C (392 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 13MoCrNi42-16-14-ANN and 13MoCrNi42-16-14 HT-CORE?
ANN is the default condition — standard as-supplied bar and forged ring condition for green machining before carburizing. HT-CORE: through hardened and multiple-tempered condition representing the tough core of a finished bearing ring, or for non-carburized structural parts. Yield strength is 560 MPa in ANN versus 1,200 MPa in HT-CORE.
How much does 13MoCrNi42-16-14 cost?
13MoCrNi42-16-14 is a high-cost steel ($$$$), pricier than about 78% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.
