Popis:	Centrifugally cast pipes from heat-resistant steels and alloys are widely used in many branches of engineering. These are radiation pipes in thermal furnaces with a protective atmosphere, bottom rollers in continuous thermal and heating furnaces of metallurgical plants, rollers in continuous annealing units, etc.The question of the possibility of increasing the operating parameters of the process of high-temperature conversion of natural gas in ammonia and methanol units is very important, because increasing the temperature and pressure not only improves the performance of the plants, but also reduces the cost of the product and allows obtaining higher purity hydrogen. In connection with the above, specialists are making efforts to improve the compositions used in steels of the type H25N35C2 by means of their additional doping.
