Phase transformations in API 5L X80 steel were studied in different thermomechanical sequences with a view to increasing the fracture toughness of this steel. Dilatometry tests performed on the quenched steel detected a phase transformation occurred, during heating, in the temperature range 593-618 K. This phase transformation was identified as the dissolution of M-A islands.
A comprehensive study on the microstructure and A typical high strength low alloy steel contains 0.070.12% carbon, up to 2% manganese and small additions of niobium, vanadium and titanium (all usually max. 0.1%) in various combinations. To other elements that might be present in such a steel belong molybdenum, zirconium, boron, aluminium, nitrogen and occasionally rare earth metals . The microalloying elements are used to refine the grain
These API 5l X80 PSL 2 Carbon Steel Pipes specifications adhere to the International Organization for Standardization, which standardizes pipeline transportation systems. These API 5L X80 PSL2 Line Pipes are broadly utilized for pipeline transportation systems
API 5L X80 PSL2 Seamless Pipe Suppliers, ISO3183 L555 Programming interface 5L-X80 steel is utilized in polar areas, wherever high sturdiness at low temperatures is required. This work look into the after effect of the cooling rate in API 5L X80 Seamless Pipe Suppliers welding on the mechanical and metallurgical properties of this kind of steel.
Evenmatched FCAW process in API 5L X80 steel welded jointFor the mechanical properties analysis, the samples were extracted from the welded test plates under different conditions. After prepared, the samples were submitted to uniaxial tensile tests which results are exposed in Table 8. According to API 5L , API 5L X80 steel has a yield strength of 550 MPa and tensile strength of 620 MPa.
properties of X80 pipeline steel were investigated by slow strain rate test (SSRT), Charpy impact test, and scanning electron microscopy (SEM) in this thesis. The results show that both the ultimate tensile strength and elongation to failure of X80 steel were deteriorated
Mechanical Properties of High-Nb X80 Steel Weld Pipes for The mechanical properties of steel pipe have great effects on the integrality and operation safety of gas transmission pipeline. In order to reduce the cost of the steel pipe, the high-Nb X80 pipeline steels with the different alloying systems have been used in the Second West-to
Microstructure And Mechanical Properties of X80/X100 Tested X80 steel plate and pipe were found to have excellent DWTT property. DWTT 85% SATT of X80 steel was about -60 in plate and -40°C in pipe. In case of X100 steel, bainitic ferrite exhibiting lath and granular type morphology was major phase and M/A existed as second phase.

"Tensile and Fracture Properties of X80 Steel Microstructures Relevant to the HAZ." Proceedings of the 2012 9th International Pipeline Conference.X80 SteelThe X80 is an American classification of high strength pipeline steel. The minimum yield value (MPa) is 555; this concept belongs to the concept of material mechanics. The yield value refers to the stress value at the yield stage when the material is stretched, and the yield stress refers to the critical value of the yield stage to the contraction stage.
