4340 - Highly alloyed steel, nominally 1.8% Ni, .80% chromium and .25% molybdenum. High strength characteristics. Used for heavily stressed parts operating in fatigue and other duty conditions.
4340 ALLOY In Stock Castle Metals SiteAlloy 4340 plate is another general purpose grade of steel used for industrial and machining applications. The inclusion of Nickel in Alloy 4340 helps simplify heat treatment. In addition, the Nickel in Alloy 4340 increases hardenability of the steel. An additional grade of Alloy 4340 is Alloy E-4340.
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 Hardened and Tempered Bar - InterlloyWelding of 4340 in the hardened and tempered condition (as normally supplied), is not recommended and should be avoided if at all possible, as the mechanical properties will
4340 High Tensile Steel Interlloy Engineering Steels 4340 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.
Low alloy 4340:ASTM A29 (VO1.05) General scope . AISI 4340 is a low alloy steel containing nominally 0.4% C, 0.8% Cr, 0.25% Mo and 1.8% Ni. Higher strength levels up to 150 KSI 0.2% PS may be achieved by suitable heat treatment.
AISI 4340 1.6511 36CrNiMo4 SNCM439 - Xingsheng AISI 4340 is defined as a heat treatable and low alloy steel which has 0.8% Cr, 0.2% Mo and 1.8% Ni as strengthening alloy elements.Compared with AISI 4140,it has higher strength and toughness,also it has very good fatigue resistance, wear resistance and atmospheric corrosion resistance.AISI 4340 is generally supplied in hardened and tempered condition with the tensile range of 930 - 1080 Mpa
AISI 4340 Steel, oil quenched 855°C (1570°F), 230°C (450°F AISI 4340 has a favorable response to heat treatment (usually oil quenching followed by tempering) and exhibits a good combination of ductility and strength when treated thusly. Uses include piston pins, bearings, ordnance, gears, dies, and pressure vessels.

May 30, 2020 · Both SAE-AISI 4140 steel and SAE-AISI 4340 steel are iron alloys. They have a very high 98% of their average alloy composition in common. For each property being compared, the top bar is SAE-AISI 4140 steel and the bottom bar is SAE-AISI 4340 steel.
SAE-AISI 4340 (SNCM439, G43400) Ni-Cr-Mo Steel SAE-AISI 4340 steel is an alloy steel formulated for primary forming into wrought products. 4340 is the designation in both the SAE and AISI systems for this material. G43400 is the UNS number. It can have a moderately high tensile strength among SAE-AISI wrought steels.
