Abstract

The mechanical properties of 0.33%C low alloy steel was investigated in the post weld heat treated (PWHT) condition, the as-received ribbed form steel was firstly machined, cut and welded using submerged arc welding (SAW) technique before subjecting it to conventional heat treatments. Microhardness and tensile tests were utilized to characterize the mechanical properties of the PWHT steel. From the results, it was observed that there was a significant improvement in the tensile (UTS and strain-to-fracture) and microhardness properties of the selected medium carbon steel.
