EFFECT OF TEMPERING ON NOTCH PROPERTIES OF D6AC ALLOY STEEL SHEET

Abstract

A study of the strength and notch properties of D6AC (consumable electrode, vacuum-melted Cr-Mo-V) steel sheet, 0.040 inch thick, was conducted to evaluate the effect of tempering for various test temperatures. Smooth tensile, edge-notched tensile, and precracked subsize Charpy specimens were employed. Tempering in the range of 1000F to 1100F provided good fracture toughness with slight loss in strength properties that would be expected at higher tempers. The results are compared with burst tests conducted on Shillelagh motor cases made from the 0.040-in.-thick D6AC steel.
