Abstract: The measurements and comparison of results are done of micro hardness measurements in the long working and weld metal of high pressure boiler drums. It is found that the least reinforced portion of the material is the body of ferrite grains, the most hardened - the body of grains of perlite.
Key words: high pressure boiler drum micro hardness pearlite ferrite
