Materials Engineering Analysis of 26NiCrMoV14-5 Steel For Machinery Component Manufacture

Original language description

In connection with requirements for improving the mechanical properties of structural steels for machinery component manufacture, it is necessary to take into account higher requirements for their metallurgical cleanliness. Metallurgical cleanliness is a significant factor affecting the steel quality. Based on the knowledge of chemical composition, we can use two critical criteria for evaluating the metallurgical cleanliness: J-factor or more precise Bruscato X-factor that selectively evaluates effect of various harmful additions. These factors evaluate steels exposed to superposition stress intensity at high temperatures in the long term. Contamination of steel by excessive presence of inclusions is a major cause leading to occurrence of degradation processes and thus to product deterioration. It is common knowledge that formation and composition of inclusions depends on chemical composition of steel and its deoxidizing and alloying method. Oxygen content and modification of inclusions in steel processing outside the furnace using calcium also have a significant impact on inclusion type and character. In order to ensure the required steel cleanliness, it is necessary to follow correct technological production method. Occurrence of breakdowns of the respective equipment in course of steel production and processing impair the steel cleanliness and quality, thus causing and developing degradation processes. The materials engineering analysis was conducted with a damaged rotor forging made of 26NiCrMoV14-5“V“steel, an ingot with a weight of 70 tons.
