Purpose: The purpose of the work was to analyse the components of X10CrWMoVNb9-2 (P92) steel in initial state and after long-term annealing for up to 100,000 h at 600 and 650°C. Design/methodology/approach: The material for investigation was X10CrWMoVNb9-2 (P92) steel in the form of a Ø160x40mm tube. The images of microstructure were recorded using the scanning electron microscopy. The quantitative...
Purpose: this article presents the results of mechanical and structure testing of X10CrMoVNb9-1 (P91) steel in initial state and after annealing, creep tests and long-term service under creep conditions Design/methodology/approach: The material for investigations was X10CrMoVNb9-1 (P91) steel in the form of two test pieces of tubes with dimensions of Ø355.6x50 mm and Ø325x38 mm in initial state and...
Design/methodology/approach: For material of the pipeline after long-term service the microstructure investigations in a scanning electron microscope, phase composition analysis of precipitations, hardness measurement at the point where structure was observed and mechanical testing at room temperature were carried out. In addition, the magnetic particle inspections and ultrasonic testing were carried...
Purpose: Condition assessment of material and welded joints with regard to required utility properties of low-alloy steel for operation at elevated temperature. Design/methodology/approach: The structural and mechanical testing of parent material and welded joint at room and elevated temperature after annealing at 550°C and 600°C for 30,000 h was carried out. Findings: The effect of temperature and...
Purpose: of this paper is to present the changes of structure in material components of the power station boiler after long-lasting annealing made X12CrCoWVNbN12-2-2 (VM12) steel. Design/methodology/approach: As a material for examination X12CrCoWVNbN12-2-2 steel was use in the form of a pipe 355.6 x 35 mm after long-lasting annealing and creeping at the temperature of 600 and 650 degrees over the...
Purpose: of this paper is to present the changes of the mechanical properties and structure in material components of the power station boiler after long-lasting annealing made of X10CrWMoVNb9-2 steel. Design/methodology/approach: As a material for examination X10CrWMoVNb9-2 steel was use in the form of a pipe Ô 160 mm and wall thickness 40mm after normalization in 1050-1070°C/1h/air and tempering...
