Also known as chrome moly steel 4140 alloy steel resists fracturing from repeated stress. Aisi 4140 steel is a low alloy steel containing chromium molybdenum and manganese. Aisi sae 4140 alloy steel is a chromium molybdenum alloy steel specification widely used in general purpose high tensile steel for components like axles shafts bolts gears and other applications. Typical properties aisi 4140 and 4150 is a medium carbon chromium molybdenum alloy steel.

The 4140 product is also available in a precision ground surface finish 25rms max. Some sizes may be calcium treated. 4140 alloy steel bars these sheets and bars are hardened for increased abrasion and impact resistance. Hardness hb sample diameter.

4140 alloy round bar. 4140 alloy steel round responds well to heat treatment and is relatively easy to machine in the annealed condition. Hardened and tempered in the tensile range of 850 1000 mpa condition t 4140 is now available with improved. Not many grades can match the versatility and usefulness of 4140.

Machinability which greatly increases feeds and or speeds while also extending tool life without adversley affecting. 4140 alloy steel round is an cold drawn annealed steel of relatively high hardenability with its chromium content provides good hardness penetration and the molybdenum imparts uniformity of hardness and high strength. Material 4140 mechanical properties are given in the table below. It is widely used across numerous industries and is an excellent material choice due to its toughness high fatigue strength and abrasion and impact resistance.
