- MachiningWeldingHeat TreatmentApplicationsStress corrosion cracking of 4340 steel in aircraft Military aircraft use a cartridge ignition system for emergency engine starts. Premature failures of steel (AISI 4340) breech chambers in which the solid propellant cartridges are burned is a serious concern. Analysis of a number of breech chamber failures identified corrosion as one problem with an indication that stress corrosion cracking may also be occurring.
AISI 4340 Alloy Steel (UNS G43400) - AZoMAlloy steels are designated by AISI four-digit numbers. They comprise different kinds of steels having composition exceeding the limitations of B, C, Mn, Mo, Ni, Si, Cr, and Va set for carbon steels. AISI 4340 alloy steel is a heat treatable and low alloy steel containing chromium, nickel and molybdenum.
High Tensile Steel, AISI 4340, 6582, ASSAB 705, SNCM439, EN24:steel 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).. AISI 4340 Steel - JIS SNCM439 - DIN 1.6563 - Songshun SteelAISI 4340 alloy steel should be in the heat treated or normalized and heat treated condition before tempering. The tempering temperature for depends upon the strength level desired. For strength levels in the 260 280 ksi range temper at 232°C (450 F). For strength in the 125

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. Corrosion Studies of Trimetallic Material in Synthetic Sea welding process in conventional mode and in pulsed mode has been investigated. The candidate materials for these studies are aeronautical steel AISI 4340 and austenitic stainless steel AISI 304L joined with filler ER309L. Potentiodynamic polarization studies were carried out on this trimetallic joints in synthetic sea water
4340 has been used typically for parts requiring a through-hardening capability up to 3.5 inches (89 mm) in nominal thickness at time of heat treatment and subject to rigid magnetic particle inspection standards, but usage is not limited to such applications. Premium Aircraft Quality is intended for use in the manufacturing of highly stressed parts at higher strength levels, such as 260/280,000 psi and where a much cleaner steel EFFECT OF SURFACE ROUGNESS IN ULTRASONIC TESTING Samples were made of steel AISI/SAE 4340 with dimensions 300 x 120 x 20 mm, (11,81 x 4,72 x 0,78 in) following the design of Thavasimuthu, et all. (3) The roughness of the front surface, of each sample, was achieved by mechanical brushing, while the back wall roughness of the sample was kept constant (0.5 m ).
steel AISI 4340 in quenched and tempered condition in the form of 16 mm diameter rods were used for friction welding. Friction welding was carried out on a continuous drive friction welding machinewith friction force of 3 kN, upsetting force of 6 kN, rotational speed of 2400 RPM, and burn-off length of Mechanical Properties and Metallurgical Characterization Apr 19, 2016 · AISI 4340, chromium-nickel-molybdenum alloy steel, has high ductility, toughness, fatigue and wear resistant property and is commonly used in aircraft landing gear, ground support systems, shaft, gear for power transmission, machine tool etc. Widespread application of austenitic and alloy steels motivated many researchers to investigate dissimilar joining between such materials.
