(PDF) Austenite Grain Growth Behavior of AISI 4140 Alloy Steel

AISI 4140 alloy steel is widely applied in the manufacture of various parts such as gears, rams, and spindles due to its good performance of strength, toughness, and wear resistance.

(PDF) Design and identification of high performance steel

Material design HSLA-100The high-strength low-alloy steel HSLA-100 was developed by the United States Navy in the early 1990s to reduce fabrication costs in ship construction (Czyryca et al., 1990a,b,c;Nichols, 1990;Sawhill, 1990). In this study, HSLA-100 is used as the reference steel alloy in examining performance improvement.

These steels exhibited low yield to tensile strength ratios and the toughness behaviour of the two steel types investigated is shown in Fig.15 which shows the ratio of dynamic to static toughness versus yield to tensile strength (Y/T) ratio. It can be seen that carbon piping steels exhibiting Y/T ratios of less than 0.5, dynamic ductile Metals Depot® - Square TubeSquare Tube is widely used in frame work and, depending upon the metal, for a broad range of other purposes. Aluminum and steel square tube is easy to weld, cut, and machine, with stainless steel square tube having easy welding and moderate cutting, forming, and machinability.
