JFE-UHP™-15CR-125
High demand for natural gas, deep water drilling and an increasing number of high pressure, high temperature (HPHT) wells has generated the need for a high strength OCTG material which can provide superior corrosion resistance at high temperatures. JFE-UHP™-15CR-125 is that material. A tempered Martensitic microstructure provides high strength at ambient and elevated temperatures with excellent corrosion resistance properties in both productive and none productive environments.
Process : Seamless
Heat Treatment : Quenched and Tempered/Ausformed Tempered

*JFE-UHP™-15CR-125 provides better tensile properties at elevated temperature than Duplex stainless steel, which requires cold drawn.
*JFE-UHP™-15CR-125 provides better corrosion resistance than Duplex stainless steel during acidizing operations.
-The corrosion testing data in this brochure were obtained from laboratory testing results. Care should always be taken when selecting materials, as operating conditions may change during the period of usage.
-Regarding completion / packer fluid
Care should be taken in the selection of well fluids such as completion/packer
fluids used in connection with this material in order to minimize the risk of
stress corrosion cracking. JFE recommends that you consult with a person knowledgeable
about fluid compatibility with this material in making a selection.
-Cr tubulars have shown a tendency toward localized pitting corrosion when
stored in moist environments.
Special precautions during coating, shipping and storage are required.
-Anti-galling connection
Cr tubulars have been categorized as prone to thread galling, JFE Steel recommends to use FOX™ and JFEBEAR™ premium connection which overcomes this concem by its special design criteria.
