How much do you know about 15Mo3 steel plate - Bebon Steel
The microstructure of 15Mo3 steel plate is pearlite + ferrite. According to the carbon equivalent formula CE (IIW) = C + Mn / 6 + (CrMo + V) / 5 + (Ni + Cu) / 15 of American Welding Association, the carbon equivalent CEV of 15Mo3 steel plate is less than 0.4%. It is said that 15Mo3 steel plate has good weldability.
Discontinuous Creep Behaviour of 15Mo3 Type Steel
15Mo3 type steel samples were subjected to creep loading at 550C in order to investigate the development of microstructure as well as the effect of the carbides. It was found that after reaching the secondary creep region, the slope of the creep curve decreased, the creep rate reached a minimum value and remained unchanged as the effect of strainhardening is counterbalanced by an annealing 15mo3 microstructure

Austenite Martensite Bainite Pearlite and Ferrite ...
Austenite was originally used to describe an iron-carbon alloy, in which the iron was in the face-centred-cubic (gamma-iron) form. It is now a term used for all iron alloys with a basis of gamma-iron. 15mo3 microstructure It is also possible to predict quantitatively the microstructure of the steel e.g. the percentage of ferrite, pearlite and bainite etc.

Bainite - Wikipedia
Bainite is a plate-like microstructure that forms in steels at temperatures of 125550 C (depending on alloy content). First described by E. S. Davenport and Edgar Bain, it is one of the products that may form when austenite (the face centered cubic crystal structure of iron) is cooled past a temperature where it no longer is 15mo3 microstructure
Welding: Solidification and Microstructure - tms.org
Parameters that control the solidification of castings also control the solidification and microstructure of welds. However, various physical processes that occur due to the interaction of the heat source with the metal during welding add a new dimension to the understanding of the weld pool solidification.

What is Bainite? - Definition from Corrosionpedia
Bainite is a crystalline microstructure that can be found in steel. Bainite forms when steel is cooled slower than the rate required to form martensite but faster than the rate that would be required to form pearlite or another slower cooling rate crystalline microstructure. Bainite is typically considered hard and brittle.

Welding is one process that is widely used during the construction. This affects the microstructure. Preheating, maintaining inter-pass temperatures, and post-weld heat treatment procedures are very critical for P91 grade. For thick walle d pipes, the use of an induction heating system is the best method.
