Description:

AISI 4140 is a 1% Cr-Mo through hardening steel, used particularly where strength and impact toughness is required.  It is generally supplied in the Hardened and Tempered condition, especially in the Oil and Gas sector to achieve Ultimate Tensile strengths in excess of 100KSI (690 MPa), moderate impact toughness (>42J) is maintained at temperatures as low as -46°C. This alloy is used in most industry sectors for a wide variety of applications.

AISI4140 can be further surface hardened by either flame or induction hardening methods, giving case hardness, in excess of 50 HR

Typical Applications:

Drive shafts, Pump Shafts, couplings, Con rods, Conveyor Pins, bolts and gears, together with many surface and sub-surface components in the oil and gas industries.

Form of supply:

Material can be supplied as Black As Rolled/Forged Bar, Proof Machined, Bright Turned or Ground Bar, Cut Pieces or Machined to customer specification.
