What is X65Cr14?
X65Cr14 (1.3542) is a higher-carbon 14 % Cr martensitic stainless bearing steel that reaches greater attainable hardness than 1.3541 after quench and temper. It is used for corrosion-resistant bearing races, bushings and wear components, and is on file annealed (A), cold-drawn (C) and in QT45, QT55, QT58 and QT60SC conditions; the default condition gives 450 MPa yield, 760 MPa tensile, 18 % elongation and 235 HB. Corrosion resistance is moderate (score 40) and service is limited to 400 °C. It is effectively non-weldable; X108CrMo17 / 440C is the nearest alternative when more hardness and molybdenum are needed. X65Cr14 has a density of 7.7 g/cm³ (0.278 lb/in³), lighter than 83% of stainless steel grades. It melts at 1,420°C (2,588 °F). X65Cr14 has a yield strength of 450 MPa (65.3 ksi) and a tensile strength of 760 MPa (110 ksi) — stronger than 70% of stainless steel grades. Elongation at break is 18% and the elastic modulus is 215 GPa (31.2 Msi).

Working with X65Cr14
Is X65Cr14 easy to machine?
Machine only in the spheroidise-annealed condition with rigid setups, sharp carbide or coated tooling and generous coolant; after hardening use grinding, honing or EDM.
Can X65Cr14 be welded?
Effectively non-weldable for structural joints — high carbon causes hard, crack-prone martensite; if unavoidable, preheat 250–350 °C, use matching or austenitic filler and temper immediately.
Can X65Cr14 be formed, bent or molded?
Cold forming is limited to gentle bends of annealed strip; hot work at 1050–850 °C followed by slow cooling and a full spheroidise anneal.
X65Cr14 chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.
| Element | Spec limit (wt %) | Nominal |
|---|---|---|
| Chigh carbon gives 58+ HRC and Cr-carbide wear resistance | 0.6 – 0.7 | 0.65 |
| Si | ≤ 0.7 | 0.35 |

What surface finishes work on X65Cr14?
Harden, then grind/polish and passivate in nitric or citric acid (ASTM A967) for full corrosion resistance; PVD/DLC or hard chrome are used where extra wear resistance is needed.

X65Cr14 — frequently asked
What is X65Cr14 used for?
X65Cr14 is typically used for stainless bearings, bushings and wear-resistant components. In short: harder than 1.3541; bearing-grade 14 % Cr stainless; not for welded joints.
What is the yield strength of X65Cr14?
X65Cr14 has a typical yield strength of 450 MPa (65.3 ksi) and a tensile strength of 760 MPa (110 ksi) — stronger than 70% of stainless steel grades. Strength varies by condition: see the 6 listed tempers.
Is X65Cr14 easy to machine?
Not especially — machinability is rated fair (42/100, better than 79% of stainless steel grades). Machine only in the spheroidise-annealed condition with rigid setups, sharp carbide or coated tooling and generous coolant; after hardening use grinding, honing or EDM.
Can X65Cr14 be welded?
Not readily — weldability is rated poor (20/100). Effectively non-weldable for structural joints — high carbon causes hard, crack-prone martensite; if unavoidable, preheat 250–350 °C, use matching or austenitic filler and temper immediately.

Cold forming is limited to gentle bends of annealed strip; hot work at 1050–850 °C followed by slow cooling and a full spheroidise anneal.
What is the maximum service temperature of X65Cr14?
X65Cr14 is rated for continuous use to about 400°C (752 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between X65Cr14-A and X65Cr14 QT60SC?
A is the default condition — stock delivery condition for machining, forming and blank preparation before hardening. QT60SC: deep-freeze treatment converts retained austenite for maximum hardness and dimensional stability in precision bearings and gauges. Yield strength is 450 MPa in A versus 1,850 MPa in QT60SC.
