Cold rolled steel will be harder/stronger/less ductile than as-rolled hot rolled of the same alloy. You should not expect to be able to spec the same tensile strength in cold rolled and hot rolled steel of identical alloy unless the hot rolled has been hardened after rolling. The properties of 4140 Cold drawn vs. Hot are different. Agreed
CD 4140 / 4142 alloy bar’s chromium content provides good hardness penetration, and the molybdenum imparts uniformity of hardness and high strength. This alloy responds well to heat treatment. In the annealed condition it machines at 110 sfm.
For each property being compared, the top bar is cold drawn SAE-AISI 1040 and the bottom bar is normalized SAE-AISI 4140. Cold Drawn 1040 Carbon Steel Normalized 4140 Cr-Mo Steel Metric Units US Customary Units

4140 cold finished annealed is a chromium-molybdenun alloy steel that can be oil hardened to relatively high hardenability. The chromium content provides good hardness penetration, and the molybdenum imparts uniformity of hardness and high strength.
Hot rolled steel actually reconfigures itself during the cooling process, giving the finished product looser tolerances than the original material and when compared to cold rolled steel products. Hot rolled steel is more malleable, allowing it to be forced into a variety of different shapes.
Cold Finished Steel Bar. Cold finished steel bars are an entire family of products that meet the standards in ASTM A108. we now have one of the most modern facilities with coil fed continuous drawing lines capable of drawing bars from just over a quarter inch to 2 inches in diameter. and squares to 2 inches in diameter.A cold drawn bar
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.

The Cold Drawing Process for Steel Bars and Wire. Finished Product: The drawn product, which is referred to as Cold Drawn or Cold Finished, exhibits a bright and/or polished finish, The cold drawing of complex shapes/profiles may require that each bar/coil be drawn several times in order to produce the desired shape and tolerances. This

I have have not done an extensive search but Metric Metals does offer 4140 Cold Drawn Annealed flat bars. as they're describing the forming process and not the process employed in production of the steel stock itself. Cold drawn bar stock is produced by starting with hot rolled bars, shotblasting them, drawing them thru reducing dies, and
One key distinction among prefabricated steel products is the difference between hot rolled versus cold rolled steel. the rolled steel into coils and leave it to cool. or tubes are
High Strength Materials SHEFFIELD™ CD – (4140 mod.) Cold Finished, Annealed Alloy Bar. Proprietary Alloy Chemistry - not a carbon steel product, nor, what many consider "cold roll", which may be 1018 or 1045.. High Strength - exhibits excellent resistance to fatigue when compared to carbon steel. Ideal for many maintenance applications where a higher degree of toughness is required.
