AISI 4140 alloy steel has good machinability in the annealed condition. Forming. AISI 4140 alloy steel has high ductility. It can be formed using conventional techniques in the annealed condition. It requires more pressure or force for forming because it is tougher than plain carbon steels. Welding
The American Iron and Steel Institute (AISI) determined the machinability ratings for a wide variety of materials. They determined this by running turning tests at 180 surface ft/min (sfpm). The AISI then arbitrarily assigned 160 Brinell B-1112 steel a machinability rating of 100%.
I 've never turned it on a lathe, but have milled quite a bit of 4140 plate on verticals and horizontal mills.I take .25 to .3 depth of cut at 850 to 900 rpm at 30 to35 ipm with a 2.0 dia iscar.I usually mill/drill at about 65 per cent feed and speed of mild steel.As mentioned earlier, the chips come off easy and it bores like a dream.

The following is a comparison of 4130 grade steel and 4140 grade steel. This information may be useful for machining purposes and as a resource for purchasing 4130 and 4140 steel. Chemical Properties The chemical properties of 4130 and 4140 steel are similar aside from differences in Carbon and Manganese concentrations.
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.
General characteristics of 4140 Alloy Steel AISI or SAE 4130 grade is a low-alloy steel containing chromium and molybdenum as strengthening agents. Its chemical composition is as follows AISI/SAE 4140 grade is a versatile alloy with good atmospheric corrosion resistance and reasonable strength.
4140 Pre Hard 4140PH is a chromium-manganese-molybdenum grade This grade is delivered in a prehardened condition at a hardness level of 33/37HRC The grade has a fully homogeneous martensite- bainite microstructure 4140PH grade has specific sulfur addition (0.060% typical) in order to increase strongly its machinability C S.4 .060 P max
Have a look at our machinability rating graph which without a doubt will make your decision a lot easier with its incredibly detailed information.
SAE 4140 grade is a low-alloy steel that contains chromium and molybdenum as strengthening agents. Its characteristics include high strength and good machinability and can be heat treated for higher hardness. This steel alloy is very versatile and has good atmospheric corrosion resistance and maintains its strength up to 600 F.
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
AISI 4140 and 4150 is a medium carbon, chromium-molybdenum alloy steel. This steel is offered in a wide range of conditions including but not limited to: cold drawn annealed, hot roll heat treated, heat treated turned ground and polished.
SAE 4140 has a machineability of around 66%, suggested surface speed is 110 ft/minute. The as-supplied hardness is somewhere around rc28-36. I would put a call into Guhring for their opinion.
AISI 4140 steel is a low alloy steel containing chromium, molybdenum, and manganese. 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. Not many grades can match the versatility and usefulness of 4140.
AISI 4140 alloy steel can be cold worked using conventional methods in the annealed condition. Annealing AISI 4140 alloy steel is annealed at 872C (1600F) followed by slowly cooling in the furnace. Tempering AISI 4140 alloy steel can be tempered at 205 to 649C (400 to 1200F) depending upon the desired hardness level. The hardness of
AISI 4140 Steel Bar, Steel Plate, Flats Supplier, Stockist and Exporter. 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.

4140 steel Heat Treatment Machinability. At the annealed condition, 1.7225 alloy tool steel has good machinability. Forming. DIN 1.7225 steel has high ductility. It can be formed using conventional techniques in the annealed condition. It is required more pressure or force for forming because it is tougher than plain carbon steels. Welding
Whether a steel is hot rolled or cold drawn determines many of the mechanical properties. The majority of 1045 and 4140 steel is purchased in cold drawn state, but we provided two graphs of both hot rolled and cold drawn mechanical properties for both 1040 and 1045. Here is a comparison chart of 1040 and 1045 hot rolled steel mechanical properties:
