In this study, the susceptibility of grade X80 pipeline steels to stress corrosion cracking (SCC) was investigated under near-neutral pH conditions and compared to that of grade X52 steel. Two grades of X80 were manufactured using the Thermo-Mechanical Controlled Process, whereas one grade of X52 was produced through Controlled Rolling.
API 5L PSL1|PSL2 line pipe specification - steels-supplierB, X42, X46 and X52, X56, X60, X70 and X80, now the big steel mills and factories have developed steel grade for X100 and X120 measures of pipeline steel. Steel pipe of higher steel grade, relatively have higher requirement of raw materials and production, the carbon equivalent between different grade of steel is strictly controlled.
API 5L steel line pipe adopts different steel grades, generally are Gr. B, X42, X46, X52, X56, X60, X65, X70, X80. Some manufacturers are capable of manufacturing steel grade up to X100 and X120. As the steel line pipe grades higher, more strictly control on the carbon equivalent control, and higher mechanical strength performances.

Measurements of the Thermophysical Properties of the Richter  and Powellhave reported physical properties as a function of temperature for a numb er of different steels. The thermal conductivity of steel alloys when temperature is decreased. The pure iron diverges having the highest thermal conductivity is followed by carbon steels, alloy steels and then by highalloy steels.
In this work three steels of class API 5L X80, with additions of, Nb-Cr, Nb-Cr-Mo and Nb-Cr-Mo-V, and otherwise similar alloy content, produced by TMCP without accelerated cooling were investigated. These alloys were submitted to austenitization at 900oC for 1 hour followed by three different cooling rates of 1.5oC/s, 30oC/s, 115oC/s, in air
