4340 steel is nickel chromium molybdenum alloy steel. It is also called JIS SNCM439 and DIN 1.6563 steel. It is an alloy structural grade which used by the SAE International(SAE), and it is chrome nickel low alloy steel. 4340 steel will get high tensile strength, hardness and toughness after heat treatment.
4340 steel has outstanding harden ability and high strength characteristics. Ideal for highly stressed parts operating under severe conditions, aircraft quality AISI 4340 steel alloy material is excellent for shafts and valves that are subject to extreme conditions.
1.Form of Supply. ASTM aisi 4340 Alloy structural steel, we can supply the 4340 round bar, steel flat bar, plate, hexagonal steel bar and steel square block. 4340 steel Round bar can be sawn to your required lengths as one offs or multiple cut pieces. 4340 Rectangular pieces can be sawn from flat bar or plate to your specific sizes.
This can result in lower case hardness or longer nitriding cycle times for steels containing nickel such as 4340. Stress Relieving Heat to 600 o C 650 o C, hold until temperature is uniform throughout the section, soak for 1 hour per 25 mm section, and cool in still air.
4340 2% Nickel Molybdenum Chromium Vanadium Through Hardening Steel. Surcharge. Scrap has fallen again for June 2019 on the back of reduced demand. Combined with slight falls in alloys, this has seen an overall reduction in surcharges this month.
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 (E4340) alloy steel is a medium carbon, low alloy steel known for its toughness and strength. Machining is done typically in the annealed condition. 4340 steel properties offer good ductility in the annealed condition, allowing it to be bent or formed.
4340 steel, as nickel chromium molybdenum alloy steel, is a very high strength steel. It is sought after for its toughness and for being used as a steel that will be highly stressed. 4340 steels are used in a variety of industries for different applications including the automotive, aerospace, and tooling industries.
Apr 24, 2017 · It can be hardened by a heat treatment followed by an oil quench, or simply by working it while cold. 4340 has average density for a steel alloy, melts at a relatively high temperature (2,600 degrees Farenheit) and is malleable enough to be "cold worked," or worked in a non heated state.
Difference Between Low Alloy Steel & High Alloy Steel. Alloy Steel is steel that is alloyed with a variety of elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties.Alloy steels are broken down into two groupslow alloy steels and high alloy steels.. High Alloy Steel. High alloy steels are defined by a high percentage of alloying elements.

Alloy 4340 AMS 6414 is a heat treatable, low alloy steel containing nickel, chromium The carbon content is nominally 0.30% and with this relatively low carbon content the Its chromium content provides good hardness penetration, and the
The 4340 alloy steel by virtue of having nickel as an alloying element increases hardenability and increases toughness over 4140. Impact energy relates to toughness but when it comes to fracture toughness data, 4340 will have higher toughness over 4140 at
Alloy 52100 is a low alloy steel which contains high levels of chromium and carbon. These alloying elements allow 51200 forgings to be through hardened as well as resistant to corrosion. • Nitralloy 135™. A low alloy steel, Nitralloy 135™ is known as a nitriding grade and is a good material for case hardening.
Alloy 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.
