The first digit "1" identifies that they are both carbon steels, and the second digit "0" identifies that there were no modifications to the alloy. Note the higher concentration of Manganese in 4140 than 1045. Mechanical Properties. Whether a steel is hot rolled or cold drawn determines many of the mechanical properties.
4140 Alloy Steel - 4140 Alloy Steel Alternative Superior Steel Alternative to. 4140 Alloy Steel. Pennsylvania Steel Corporation presents an alternative to SAE 4140 alloy steel. FLEXOR®'s chemistry and mechanical properties are comparable, if not superior to 4140 alloy steel and thusly, can be utilized in most of the same applications.
Nov 05, 2019 · 4140 is a great basic chemistry that is easily modified at the steel mill by use of additional elements to achieve additional, and/or, specific properties for specific industries or jobs. For instance, if you need high hardness that is deeper and more uniform, you could add Nickel to the 4140.

IntroductionChemical CompositionMachiningWeldabilityHeat TreatmentForgingNitridingTemperingFlame and Induction HardeningAISI 4140 is a chromium-molybdenum alloy steel. The chromium content provides good hardness penetration, and the molybdenum content ensures uniform hardness and high strength. AISI 4140 chrome-molybdenum steel can be oil hardened to a relatively high level of hardness. The desirable properties of the AISI 4140 include superior toughness, good ductility and good wear resistance in the quenched and tempered condition.The AISI 4140 cold finished annealed chromium-molybdenun alloy s4140 Steel & 4150 Steel Specialty Steel Co.Typical Properties 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.
The AISI 4140 cold finished annealed chromium-molybdenun alloy steel can be heated using various methods to yield a wide range of properties, hence it is often used as stock for forging as it has self-scaling properties. AISI 4140 is capable of resisting creep in temperatures up to 538°C (1000°F) and maintaining its properties even after long

Welding 4140Welding 4140 is a lot like welding 4130 which is a lot like welding plain old steel. Except for being more crack sensitive and therefore needing a preheat before welding on certain applications, the puddle looks very much the same as welding plain carbon steel thats because the composition is so similar. 4130 and 4140 are low alloy steels.Handbook:Everything You Should Know About 4140 SteelWhat are the Mechanical Properties of 4140 Steel? The presence of chromium and molybdenum tends to give 4140 steel some extra mechanical advantages than ordinary steel. It is harder than regular steel. The steel has an excellent weight to strength ratio. This means that despite being physically and mechanically stronger, 4140 is not very heavy.
