- IntroductionChemical CompositionMachiningWeldabilityHeat TreatmentForgingStress RelievingAnnealingNormalizingNitridingAISI 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 ASTM A322 : Translate this pageFeb 26, 2020 · A Small quantities of certain elements are present in alloy steels which are not specified or required. These elements are considered as incidental and may be present to the following maximum amounts:copper 0.35 %, nickel 0.25 %, chromium 0.20 %, and molybdenum 0.06 %. B Standard alloy steels can be produced with a lead range of 0.15 to 0.35 %.
AISI 4340 HT Steel Double Eagle AlloysAISI 4340 alloy steel is a medium carbon nickel-chromium molybdenum alloy steel that creates an excellent combination of ductility, toughness, and strength after heat treating. It has good shock and impact resistance as well as wear and abrasion resistance in the hardened condition.

Alloy Steel 4340 Round Bar UNS# G43400 ium Alloy Steel 4340 UNS# G43400 is a nickel-chromium-molybdenum alloy steel that demonstrates good toughness and good fatigue resistance. When heat treated, Alloy Steel 4340 maintains good wear resistance, good atmospheric corrosion resistance, and other similar traits. Because of these desirable characteristics, Alloy Steel 4340 is often used Alloys - Alloy Steels Round bars Importer from Mumbai4340 is a 1.8% nickel - chromium - molybdenum high hardenability high tensile steel - generally supplied hardened and tempered in the tensile range of 930 - 1080 Mpa (condition U) - (Rc 28 - 36)..Characterised by high strength and toughness in relatively large sections.Pre hardened and tempered 4340 can be further surface hardened by flame or

Molybdenum can be rolled threaded, but this method is slow, and the preferred, faster methods consist of turning or chasing. Heat the moly and the die to 162°C for best results. Molybdenum can be heated to
4130 Steel (also known as AISI 4130 & SAE 4130) is a chromium molybdenum low-alloy steel with considerably higher strength & toughness than the typical steel grade. Additionally, the reduced carbon level of this alloy, while limiting thickness strength, provides improved weldability over its 4140 steel counterpart. These attributes have made AISI 4130 a popular Standard Specication for Steel Bars, Alloy, Standard chemical composition in Table 1 for the grade specied.
