Nov 05, 2019 · 4140 is pretty much the Defacto-Standard for a good all-around general-purpose maintenance steel for replacement parts. It has been designed to possess high strength (sometimes referred to as ultra-high strength), along with noticeable resistance to gouging, bending, fatigue, wear, and to an extent even corrosion. 4140 may be supplied in several hardness ranges to deliver several levels of strength.

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 High Tensile Steel Interlloy Engineering Steels 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.

Simply put, carbon steel by definition is extremely simple. Its Iron with some carbon, and limited alloying elements. In addition, any steel that requires alloying elements (like 4140 and 4340, for example) are not carbon steels. Within the carbon steel definition, materials can be defined as either low-carbon steel or high-carbon steel.

Cold finished carbon steel bars are machine straightened within reasonable limits and suitable for the majority of industrial uses. The degree of straightness is satisfactory for operation in an automatic screw machine. Inspection prior to altering material is advisable. It is not advisable to try to finish on size from the size purchased.
What is 41L40 Steel & 41L40 Steel Properties - 41L40 vs Steel 4140 (AISI 4140) is a low alloy steel containing chromium, molybdenum, and manganese.
