4140 Tool Steel Grade, Shape, Size, Tech - Tool Steel AISI 4140 is an alloy steel that is supplied in either annealed or prehardened condition. The alloy steel is composed of chromium, molybdenum, manganese containing low alloy steel. It is characterized by its high fatigue strength, torsional strength, abrasion resistance, toughness.
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 sDatasheet for Steel Grades Carbon Steel SAE 4140This page is mainly introduced the SAE 4140 Datasheet, including chemical information,mechanical properties, physical properties, mechanical properties, heat treatment, and Micro structure, etc. It also contains the use of SAE 4140,such as it is commonly used in bars, sheet,plates, steel coils, steel pipes,forged and other materials application.

Welding 4150 Ordinance Steel - GunloadsDec 26, 2012 · I have welded a little 4140 steel and found it considerably harder to weld than 4130. There is a serious problem with "hot-cracking". I have not welded any 4150 steel, but I imagine it would be even more difficult. The main difference between 4130 and 4150 is the amount of carbon in it. There is more carbon the higher the number.
Mar 23, 2016 · The next three numbers [list other elements in the alloy]. 4140, also known as ordnance steel, was one of the early high-alloy steels. It has about 1 percent chromium, 0.25 percent molybdenum, 0.4 percent carbon, 1 percent manganese, around 0.2 percent silicon and no more than 0.035 percent phosphorus and no more than 0.04 percent sulphur.
