D2 H13 1045 4340 4140 P20 Hot Rolled Forged Round Steel Bar 1 4340 steel introduction AISI 4340 steel is a medium carbon,low alloy steel known for its toughness and Favorites HUNAN QILU INDUSTRIAL CO.,LTD. results for this questionWhat is AISI 4140 steel?What is AISI 4140 steel?AISI 4140 steel is alloyed with chromium and molybdenum,hence the term chromoly steel.The addition of these alloying elements and its relatively high carbon content (around 0.40%) provide this low-alloy steel with excellent strength to weight ratio and make it a lot stronger and harder than standard 1018 and 1020 steels.How To Weld 4140 Steel WELDING ANSWERS
The carbon content of both 1045 and 4140 determines the last two digits of their grade number.The carbon content of 1040 steel is 0.40%,while 1045 has a carbon content of 0.45%.The first digit 1 identifies that they are both carbon steels,and the second digit 0 identifies that there were no modifications to the alloy.
