FILLER METAL, ELECTRODE AND FILLER WIRE FOR SAE 4340 STEEL, 260-292 KSI HEAT TREAT RANGE, EVALUATION OF

Abstract

Tensile and hardness tests were made of welds in SAE 4340 steel to determine which of 6 candidate electrodes and filler wires will provide welds heat treatable to the 260 to 292 ksi strength level. All the specimens were heat treated by heating to 1550 F, holding 30 min, quenching in oil, and double tempering for 2 hr at 400 F. None of the candidate filler materials consistently provided welds in the 260-292 ksi strength range in 4340 plate.
