Tubing and casing hanger API 6A 718, alloy 718, UNS N07718,
W.Nr.2.4668 for sulfurous oil-gas engineering
Tubing hanger, tubing suspender for sulfurous oil gas drilling and
production equipment (material API 6A 718)
(1) The alloy 718 is a nickel based age hardened high temperature
(2) The material has good comprehensive performance in the
temperature range of -253~700℃.
(3) Its yield strength below 650℃ ranks first in all wrought high
(4) It has good resistance against fatigue, radiation, oxidation
and corrosion, as well as good processability, welding performance
and long-term structure stability.
(5) Its structure is particularly sensitive to thermal processing
technology, by mastering the relationship between phase
precipitation and dissolution in the alloy, as well as the
structure, process and properties, reasonable and feasible process
procedures can be formulated, so as to making various parts that
can meet different strength levels and usage requirements.
(6) Its welding characteristics, especially its resistance to
post-weld cracking, are outstanding.
(1) More than 50 years experience of research and develop in high
temperature alloy, corrosion resistance alloy, precision alloy,
refractory alloy, rare metal and precious metal material and
(2) 6 state key laboratories and calibration center.
(3) Hundreds of patent technologies.
(4) Excellent performance when running in oil-gas well several tens
of thousands of meters deep.
(5) We have terminal customers like Baker Hughes, Halliburton,
China national offshore oil corporation LTD (CNOOC), etc.
