Abstract

Type 316L weld metals contained various delta ferrites ranging from 0% to 9. 5%, which were deposited by one pass submerged arc welding, were heat treated at 923 K to 1523 K for 2 s to 86. 4 Ks (24 h). From the results of absorbed energy at 77 K and analysis of precipitates by electron and x-ray diffractions, the influence of reheating on low temperature toughness was investigated. The absorbed energies of weld metals which contained some delta ferrites decreased with the increase in the heat treating time and this decreasing rate was pronounced at more delta ferrite content and high heat treating temperature. However, in the case for short heat treating time within 120 seconds, the absorbed energy had a tendency to increase, compared with as-welded one, while in the fully austenitic weld metal, the decrease in absorbed energy could be scarcely detected independent of the heat treating time.
