Evaluation of toughness in AISI 4340 alloy steel

ROBERT O. RITCHIE, BENJAMIN FRANCIS, AND WILLIAM L. SERVER It has been reported for as quenched AISI 4340 steel that high temperature austenitizing treatments at 1200~ instead of conventional heat treatment at 870~ result in a two fold increase in fracture toughness, Ktc , but a dec~'ease in Charpy impact energy.

300M Alloy Steel (4340M) Rough Turned & Vacuum Arc

300M Alloy Steel (4340M) 300M is a vacuum melted low alloy steel with the inclusion of vanadium and a higher silicon composition. It has a very good fatigue strength and resilience. Where fracture toughness and impact strength are crucial, 300M is a great choice.

Alloy Steel Types, Properties and Uses

300M is a low alloy, vacuum melted, steel of very high strength. Essentially it is a modified AISI 4340 steel with silicon, vanadium and slightly greater carbon and molybdenum content than 4340. 300M has a very good combination of strength (1900 2100 MPA after final heat treatment), toughness,

Different Steel Types and Properties

AusteniticAustenitic steels are non magnetic and non heat treatable, and generally contain 18% chromium, 8% nickel and less than 0.8% carbon. Austenitic steels form the largest portion of the global stainless steel market and are often used in food processing equipment, kitchen utensils, and piping.

Difference Between Low Alloy Steel & High Alloy Steel

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.
