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.
Proper heat-treating procedures will produce tensile strengths of 190,000 - 265,000 psi.
Hardness varies with heat-treating.
PLEASE SELECT DIAMETER(S) FROM ABOVE.
