AISI 4340 (E4340) alloy steel is a medium carbon, low alloy steel known for providing a good balance between strength and malleability. Alloy 4340 is composed of (descending in order by weight):iron, nickel, chromium, manganese, carbon, molybdenum, silicon, phosphorus and sulfur. With proper working and strengthening, items made from 4340 have excellent wear and durability qualities. 4340 High Tensile Steel - Engineering Steels + Alloys4340 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.

300M is a low alloy, vacuum melted steel of very high strength and hardenability. Essentially it is a modified AISI 4340 steel with silicon, vanadium and slightly more carbon and molybdenum. 300M has a very good combination of strength in the 280-305 KSI range (19302100 MPa). It is a through hardening alloy with a combination of high toughness, fatigue strength and good ductility. Alloy Steel 4340 - Wingate Alloys IncAISI 4340 is a heat treatable, low alloy steel containing nickel, chromium, and molybdenum. The inclusion of nickel improves hardenability. Regarded industry-wide for its toughness, 4340 supplies high strength in the heat treated condition while still maintaining excellent fatigue strength over time.

Mar 23, 2015 · This article is the second in a four-part series on the different types of steel.Read Part 1.. Alloy steels are made by combining carbon steel with one or several alloying elements, such as manganese, silicon, nickel, titanium, copper, chromium and aluminum. Carbon Steel Alloys Coburn-Myers4340. G43400:4340 is a heat treatable, low alloy steel containing nickel, chromium, and molybdenum. It is known for its toughness and capability of developing high strength in the heat treated condition, while retaining good fatigue strength. Typically used for aircraft landing gear, power transmission gears and shafts, and other structural parts. Carbon Steels and Alloy Steels Selection Guide Steels above a carbon content of 1.2% are generally formed through powder metallurgy. Steels with carbon content above 2% are considered to be cast iron. Alloy steels contain varying amounts of different metals and materials to specialize their properties. Some of the most common materials added include chromium, molybdenum, nickel, and silicon.
Dec 09, 2018 · Steel alloys, like stainless steel, have become ubiquitous materials for constructing everything from household cookware to buildings to modern art. The alloy has many attributes that make it useful, such as an excellent shine, a surface that resists corrosion and rust and that is durable under harsh weather conditions. SAE AISI 4340 Steel Properties, Heat Treatment, Equivalent 4340 Steel Heat Treatment. Alloy steel 4340 heat treatment including:normalizing, annealing, hardening, tempering, spheroidization, stress relief, etc. (4340 heat treat) Normalizing:Heat to 845 to 900 °C (1550 to 1650 °F) and hold for a period of time, which depends on the thickness of Steel Alloys and Their ClassificationHere are two examples of steel alloys:Low Alloy Steel - Usually iron base alloys, which can be hardened to high strength. A common steel alloy for use in the 180 to 200 ksi (1 ksi = 1000 psi) strength range is AISI 4130. Another type is AISI 4340, with a strength range from 200 ksi to 280 ksi, which is used in the 260 to 280 ksi range.
Other designations of AISI 4340 alloy steel include UNS G43400 and AISI 4340. Steel is the common name for a large family of iron alloys. Steels can either be cast directly to shape, or into ingots which are reheated and hot worked into a wrought shape by forging, extrusion, rolling, or other processes. eFunda:Properties of Alloy Steel AISI 4340Category :Steel:Class :Alloy steel:Type :Standard:Common Names :Nickel-chromium-molybdenum steel:Designations :Germany:DIN 1.6565 Japan:JIS SNCM 8 United 4340 Alloy Steel Is a King of Among Alloys Known for its The 4340 alloy steel bar is used heavily in construction across industries because of its ultra-high strength. This nickel-chromium-molybdenum alloy steel attains its high strength when heat-treated and has excellent resistance to fatigue. 4340s richer alloy content provides it with much deeper harden ability than the 4100 series of alloys.
