What is AMS 6414?
4340 VAC AMS 6414 is a low alloy steel, maintaining high strength when heated. Typical applications of 4340 AMS 6414 include the aerospace and defense industries for structural use, including aircraft landing gear and power transmission gears. It offers good machinability in the normal, annealed or tempered conditions.
What is the difference between E4340 and 4340?
Technical Data Sheet. Alloy E 4340 is a widely used deep-hardening constructional steel. Due to E-4340’s high alloy content it obtains a uniformed hardness by heat treatment. The high fatigue strength makes E4340 ideal for highly stress parts as it maintains it’s strength and hardness at elevated temperatures.
What is 4340 var?
4340 VAR is a chromium nickel molybdenum alloy. It is used at a variety of strength levels and at each level possesses remarkable ductility and toughness. With its high alloy content uniform hardness is developed by heat treatment in relatively heavy sections.
Is 4340 stainless steel?
AISI 4340 alloy steel is a heat treatable and low alloy steel containing chromium, nickel and molybdenum. It has high toughness and strength in the heat treated condition.
What is E4340 steel?
E4340 is a highly alloyed, electric-furnace processed; vacuum degassed grade, which conforms to the rigid aircraft standards of AMS-2301. It contains approximately 0.8% chromium, 1.8% nickel, and 25% molybdenum.
Where is 4340 steel used?
aircraft landing gears
4340 steel alloy is used primarily for structural applications such as aircraft landing gears. 4340 alloy steel is also used in the manufacturing of structural parts like gears, sprockets, chucks, molds, and more.
Is AISI 4340 steel magnetic?
SAE 4340 steel has demonstrated interesting applications where good mechanical and magnetic properties are necessary, at a low cost. This steel presents a good hardening ability that promotes the improving of its mechanical properties when submitted to quenching and tempering.
Is 4140 an alloy steel?
4140 steel is a chromium, molybdenum, manganese low alloy steel plate that is known for its toughness, high fatigue strength, and high torsional strength.
What is the hardness of 4140 steel?
4140 (modified) Cold Finished, Annealed Alloy Bar Stock It is offered in the cold finished annealed condition. Typical hardness is Rockwell “C” 19/24. Typical tensile strength 114,000 PSI. Its wear resistant properties far exceed that of “cold roll” steels.
What is the HRC of 4340?
24 to 53
4340 has high strength, ductility, toughness, creep resistance, and fatigue resistance relative to most other steels. High degrees of hardenability are achievable in the alloy, with HRC hardnesses ranging from 24 to 53 depending on the heat treatment.
