4140 vs 4130 Steel:The Right Steel for Your Project

Aug 03, 2021 · 4140 steel is similar to 4130 steel in terms of composition. However, there is a difference in carbon content, with 4140 steel having 0.38-0.43 % while 4130 steel has 0.28-0.33 %. This difference is responsible for the different 4130 and 4140 steel properties seen. 4340 ALLOY In Stock Castle Metals SiteAlloy 4340 in Plate SPECIFICATIONS:AISI4340, ASTM A 829 / A6 SAE J404, AMS 2252/ 2301/6359 SAE J404 Castle Metals stocks Alloy 4340 plate through our global distribution network.

AISI/SAE 4340 Alloy Steel- 4340 Steel Properties All

AISI/SAE 4340 Alloy Steel, 4340, is a nickel-chromium-molybdenum alloy steel known for its toughness and its ability to attain high strengths in the heat-treated condition. Commercial and military aircraft, automotive systems, forged hydraulic and other machine tool applications, forged steel crankshafts. Bar and Plate Products - AlroTool Steel ® 8-1 alro Alro Steel Metals Guide AISI 4340 Hot Rolled .. 8-19 thru 8-21 AISI 6150 HR Annealed .. 8-22 thru 8-25 In conditions where localized hardness may be required, this steel is readily flame or induction hardened. *Applies only to 4140 leaded alloy steel bars. HR / CF (Also available in DCF) Typical Analysis Encore Metals - 43404340. Richly alloyed heavy-duty steel, this nickel-chromium- molybdenum alloy possesses much deeper hardenability than the 4100 series, with increased ductility and toughness. These advantages are realized principally where high strength is required in heavy sections. Also the high fatigue strength of 4340 makes it ideal for all highly stressed
