介绍 | Carpenter SCF 260™ alloy is an austenitic, nitrogen-strengthened stainless steel. It can be considered for down-hole applications in the oil and gas industry including but not limited to drill collars, stabilizers, and MWD/LWD housings. Carpenter SCF 260 alloy possesses an excellent combination of strength including rotating fatigue, and corrosion resistance in chloride environments. In addition, a special ID treatment applied to hollow bars has been shown to enhance stress-corrosion cracking resistance. The controlled chemistry of this alloy has provided a PREN of higher than 35, yielding superior pitting corrosion resistance. Careful control of chemistry and processing results in fewer grain-boundary carbides and increased strength. This alloy is capable of high strength, improved chloride pitting corrosion, and enhanced fatigue properties compared to competitive Cr-Mn-N alloys. |
