SP-SSRT법에 의한 TMCP강 용접부의 응력부식균열 평가에 관한 연구
A Study on the Stress Corrosion Cracking Evaluation for Weld Joint of TMCP steel by SP-SSRT Method
초록
The object of this paper is to evaluate SCC(stress corrosion cracking) susceptibility for parent metal and bond line region of weld joints which have the various weld heat input condtions in TMCP(thermo-mechanical control process) steel by SP-SSRT(small punch-slow strain rate test) method. And the SCC test results of TMCP steel are compared with those of the conventional HT50 steel which has te almost same tensile strength level like TMCP steel. The loading rate used was
