Corrosion characterization of new low manganese microalloyed X65 steels in sour and NON-SOUR synthetic seawater

Journal of Materials Research and Technology, 2022
API 5L X65 microalloyed steels are extensively used for oil and gas transportation. In many cases, reserves of such resources contain H2S, constituting what is called a sour medium, at which hydrogen-induced failures are critical.

Evolution of precipitates, in particular cruciform and cuboid particles, during simulated direct charging of thin slab cast vanadium microalloyed steels [PDF]

, 2004
A study has been undertaken of four vanadium based steels which have been processed by a simulated direct charging route using processing parameters typical of thin slab casting, where the cast product has a thickness of 50 to 80mm ( in this study 50 mm)

Effects of Grain Refinement on the Corrosion Behaviour of Microalloyed Steel in Sulphuric Acid Solutions

International Journal of Electrochemical Science, 2012
Microalloyed steels have been widely used in many applications, particularly in car bodies and other engineering parts. This is because these steels are characterized by their high strength and high ductility.

New approach for modelling strain induced precipitation of Nb(C,N) in HSLA steels during multipass hot deformation in austenite [PDF]

, 2009
A new model for strain induced precipitation of Nb(C,N) is developed from the existing model for single pass hot deformation. This new model can be extended to multipass deformation to explain the microstructural evolution during the hot deformation of ...

Effects of Niobium Addition on the Mechanical Properties and Corrosion Resistance of Microalloyed Steels: A Review

Buildings
Steel structures are prone to corrosion, a chemical reaction between steel and the atmosphere that gradually weakens the material. Over time, this reaction can significantly reduce the structural integrity and lifespan of steel elements.

Selected Problems of the Microstructure Evolution During Microalloyed Steel Wire Rod Production Process

Archives of Metallurgy and Materials, 2017
In the present study, we have discussed the selected problems of microstructure development during the whole manufacturing process, i.e. continuous casting, thermomechanical processing, and cold metal forming of the microalloyed steels wires.
