Nature of the intergranular cracks in the blanks of chrome nickel molybdenum steel and development of methods to avoid them
In the article the research of nature of intergranular cracks in the blanks of chrome nickel molybdenum steel and methods to avoid them are presented. It was determined that the cause of these defects are non-metallic films based on the aluminum nitride and manganese sulfide. Recommendations to modify the existing technology of manufacturing of blanks for all phases of metallurgical processing are suggested.
