With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
Microstructure and properties of Inconel 625 coatings deposited by the Cold Metal Transfer technique on a 16Mo3 boiler tube were investigated. The clad layers were shown to have a typical cellular-dendritic structure with secondary phases in the interdendritic regions (e.g. Laves phases and complex nitrides/carbides (MX)).

Annealing effect on microstructure and chemical composition of Inconel 625 alloy Wpyw wyarzania na mikrostruktur i skad chemiczny stopu Inconel 625 Abstract Our research focused on Inconel 625 weld overlays on 16Mo3 steel boiler pipes. The investiga-tion focused on the characterization of changes in the microstructure and chemical composi-
resistant steels (P235GH, P265GH, 16Mo3 and 13CrMo4-5), which can withstand the long-term temperatures up to (450 560) C. For this purpose, the yield-stress theory has been proposed along with predictive nomograms in order to define the grain size of a ferrite, the volume fraction of a pearlite and other
Microstructures and Effects on Properties Literature suggests that microstructure and grain morphology affects the tensile and mechanical properties of Ti-6Al-4V. Controlling morphology of the sample can be done through heat treatment and cooling rates. As suggested low to intermediate cooling
16Mo3 is a EN10028 specified pressure vessel grade chrome molybdenum steel alloy for use in elevated working temperatures. The material is used as a weldable steel in the fabrication of industrial boilers and steel pressurised vessels found in the oil, gas and chemical industry.
Molybdenum in solid solution reduces the creep rate of steel very effectively. It slows the coagulation and coarsening (Ostwald ripening) of carbides during high-temperature service. The best results in terms of elevated-temperature strength are obtained by quenching and tempering to produce a microstructure consisting of upper bainite.

Classification of Carbon and Low-Alloy Steels. Steels can be classified by a variety of different systems depending on: The composition, such as carbon, low-alloy or stainless steel. The manufacturing methods, such as open hearth, basic oxygen process, or electric furnace methods.
Reliable microstructure for better creep resistance at elevated temperature Excellent low temperature impact toughness properties. Oerlikon CROMOCORD Kb has regularly earned reputation has a much higher heat resistance and it is thus exceptionally useful for applications where hot fluids or gases are being processed at high temperatures.

The term microstructure is used to describe the appearance of the material on the nm-cm length scale. A reasonable working denition of microstructure is: Microstructure can be observed using a range of microscopy techniques. The microstructural features of a given material may vary greatly when observed at different length scales.
The paper presents the research on the microstructure and mechanical properties of a pipe made of 16Mo3 steel, overlaid with superalloy based on Haynes NiCro625 nickel. The overlay weld was overlaid using the MIG (131) method.
Its microstructure and mechanical properties are enhanced using SLM (selective laser melting) which is a 3D printing technique using powder and melting the particles together using high powered laser. Other conventional techniques for improving the microstructure are thermal processes.
The basic material, 16Mo3 steel, was characterized by a ferritic pearlitic microstructure, typical for this grade of steel fig. 2a). in the heat-affected zone (haz), however, adiverse microstructure was observed: from martensitic, through martensitic bainitic, to ferritic bainitic microstructure Fig.

Microstructures - An Overview What is a microstructure? Metals are crystalline when in the solid form. The crystal structure of a solid metal refers to the internal structure or arrangement of the atoms in an ordered, repeating, three dimensional pattern.
Therefore; the microstructure and mechanical properties of the materials could be improved depending on the applied heat treatment conditions (stress relieving, normalization, tempering etc.) in the processes of sheet material forming [7-10]. In the conducted experimental study, deformation implementations were carried out with the use of 16Mo3
The rolling mill at Dillingen can deliver 11,000 tonnes of force enabling it to deform the core of 400mm ASME SA516 Grade 70 slabs to produce S A516 Grade 70 plates that have a consistent microstructure throughout the plate.
Microstructure definition is - the microscopic structure of a material (such as a mineral or a biological cell).
