(PDF) Alloy 718 Subsea Bolt in Relation to Surface

Dec 03, 2020 · 8 × 718 subsea bolts implied that they were heat-treated, as per the API 6A718 specification for oilfield specification , followed by cold rolling of threads before deploying in subsea. 1. Introduction - SCIRPTo mitigate this issue, alloy 718 for oilfield applications relies on unique chemistry, heat treatment (as per API 6A718 standard spec [7] ), and microstructure to resist stress corrosion cracking; however, the microstructure of Inconel 718 bolts strongly depends on the manufacturing sequence.
