Datasheet for Steel Grades Carbon Steel AISI 4340

This page is mainly introduced the AISI 4340 Datasheet, including chemical information,mechanical properties, physical properties, mechanical properties, heat treatment, and Micro structure, etc. It also contains the use of AISI 4340,such as it is commonly used in bars, sheet,plates, steel coils, steel pipes,forged and other materials application. EVALUATION OF CHATTER VIBRATION FREQUENCY IN The work piece material used for the study is AISI 4340 round steel bars with nominal dimensions of 381 mm (length) and 38.1 mm diameter. Cutting process was orthogonal turning and workpieces were unstopped. Parameters for experiments were selected from analytical results for Effect of Heat Treatment on Hardness and Microstructures The SAE/ AISI 1045, a type of medium carbon steel, is used most commonly in various structural and element of machines. Sometime, it failed during the in-service, which assumed to be caused by cracking in material as the effect of casting, manufacturing, or heat treatment processes. The current research was developed to find out the effect of hardening and of tempering processes toward

Improving the Microstructure, Mechanical and Magnetic AISI 4340 steel is one of the super strong steels that can be selected for different applications. mechanical and magnetic properties of AISI 4340 steel. The results of tensile, impact, hardness, metallography and magnetic tests for various samples under different heat treatment cycles showed that parameters such as turn, increased the Influence of Tempering in Different Melting Routes on Oct 13, 2020 · Martensitic microstructure of AISI 4340 steel can be heat treated to achieve the desired mechanical properties. However, mechanical properties degrade owing to the impurities and cleanliness during the steel production. In this work, AISI 4340 steel was produced through three different routes, such as vacuum degassing (VD), electro slag remelting (ESR), and vacuum arc remelting (VAR),

Machinability of Steel - Machining Doctor

(The most common example is the widely used SAE 4340 DIN 35CrNiMo6). However, carbon content is still the dominant factor influencing machinability. Materials like SAE 52100 DIN 100Cr6 that have 1% carbon content, show the lowest machinability rating in this group, although they dont contain any Nickel. Mechanical Characterization and Microstructural Analysis AISI 4340 steel is a low alloy medium carbon steel, containing different alloying elements such as chromium, nickel and molybdenum. Chromium and molybdenum serve as ferrite stabilizers or carbide formers to improve hardness and wear resistance of the steel with better strength. Chromium also improves corrosion and wear resistance. Metallography Flashcards QuizletStart studying Metallography. Learn vocabulary, terms, and more with flashcards, games, and other study tools.

Hard turning:AISI 4340 high strength low alloy steel and

Dec 01, 2005 · Strafford and Audy investigated the relationship between hardness and machining forces during turning of AISI 4340 steel hardened from 29 to 57 HRC with mixed alumina tools. The results suggest that an increase of 48% in hardness leads to an increase in the machining forces from 30 to
