Notes
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.
