performance in the environment where hydrogen sulfide corrosion exists.After an indepth study, we has successfully
developed tubular goods of the Cr-Mo series for this purpose with good hardenability and tempering stability that when
tempering takes places at certain temperatures uniform and fine sorbite structures can be obtained. Their mechanical
properties can meet fully the requirements of corresponding grades and their anti-SSC performance is excellent by
regulating the chemical composition and adopting different heat treatment procedures.
