This study investigated the failure of a 15-5 PH (UNS S15500) precipitation-hardened stainless steel stem when installed in a 5 1/8in. (130-mm) hydraulic surface safety gate valve working in a sour gas environment. The results indicate that the fracture failure was caused by sulfide stress cracking, which progressed transgranularly in the martensitic matrix. 2 Materials Performance 47 ARTICULO Mostofi, J. 51114 Zamanian, M. 51115 184723 184723 0 0 0 0 252542 BAAB BAAB 2026-03-06 200056784 0 200056784 2026-03-06 00:09:35 2026-03-06 ARTICULO
