Paper Number: NACE-2019-12765
... ABSTRACT Looking at martensitic stainless steels (MSS) NACE MR0175 / ISO 15156 lists six tables with different H 2 S acceptance levels. Generic Table A.18 lists several MSS with a maximum allowable partial pressure H 2 S of 0.1 bar whilst equipment specific Table A.23 (Wellhead and tree...

... manufactured or exposed to aggressive environments. In this paper, three modes of CRA failure observed at a client’s site were analyzed in a lab and mitigation strategies proposed. Tower trays near the top of a crude tower made of UNS S41008 martensitic stainless steel (SS) failed as a result of localized...

... ABSTRACT The precipitation strengthened martensitic stainless steel has been the material of choice for a continuous steel belt used in panel-board pressing. By being subjected to periodic denting with ensuing fatigue cracking it must be repaired in the field in order to avoid costly and time...

... economical aspects are a critical issue. The first grade studied is the UNS17400 (1.4542) martensitic stainless steel largely used in this kind of applications, but now limited by the NACE standard MR0175 (2003 edition) to high pH (>4.5) and only for well head applications. The second grade is the 1.4418...

... martensitic stainless steels.1-12 Modified refers to alteration of typical alloying element contents from the base AISI420 13Cr grade (UNS S42000); modified 13Cr martensitic stainless steels typically have lower C, higher Ni, and higher Mo compared to AISI420. Research has found that many factors affect...
