4140 round bar properties.

Typical properties aisi 4140 and 4150 is a medium carbon chromium molybdenum alloy steel. Some sizes may be calcium treated. 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. Shafts gears bolts studs connecting rods spindles tool holders.

Tensile strength mpa yield strength mpa elongation in 50 mm. 4140 is a 1 chromium molybdenum medium hardenability general purpose high tensile steel generally supplied hardened and tempered in the tensile range of 850 1000 mpa condition t 4140 is now available with improved machinability which greatly increases feeds and or speeds while also extending tool life without adversley affecting mechanical properties. Steel 4130 4140 round bar. Hardened and tempered in the tensile range of 850 1000 mpa condition t 4140 is now available with improved.

4140 alloy steel round responds well to heat treatment and is relatively easy to machine in the annealed condition. The 4140 product is also available in a precision ground surface finish 25rms max. 4140 is a 1 chromium molybdenum medium hardenability general purpose high tensile steel generally supplied. Hardness hb sample diameter.

Not many grades can match the versatility and usefulness of 4140. 4140 alloy steel round has good strength and wear resistance excellent toughness coupled with good ductility and the ability to resist. Similar to alloy grade aisi 4130 chrome moly alloy steel but with a slightly higher. Also known as chrome moly steel 4140 alloy steel resists fracturing from repeated stress.
