Properties & Uses for the 4340 Grades of Steel Sciencing

Apr 24, 2017 · Composition. Steel alloy 4340 is composed of (descending in order by weight)iron, nickel, chromium, manganese, carbon, molybdenum, silicon, phosphorus and sulfur. It can be hardened by a heat treatment followed by an oil quench, or simply by working it while cold. 4340 has average density for a steel alloy, melts at a relatively high temperature

ER 4340 - Mild Steel TIG Welding Rod - 1lb. Pack ER 4340

ER 4340 - AISI 4340. ER4340 is a low alloy, copper-coated wire designed for the welding of heat-treatable, low alloy steels such as the SAI / AISI 4300 series where higher carbon grades are used or where greater tensile strengths are desired. A pre-heat of 400°F - 550°F is required for some of the higher carbon grades to prevent cracking.
