Stress cracking of stainless steel safety gate valve stem
Publication details: feb. 2008Description: 4 p. ; 64-67 In: Materials Performance 47Summary: Transcripción del resumen del autor. 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.| Current library | Status | Barcode | |
