Abstract
The paper studies heat resistance properties of 45Cr32Ni43SiNb alloy developed at the CRISM “Prometey” for reformer systems of high-temperature ethylene production plants. The macrocrystalline structure is analyzed and quantitative phase data for metal of centrifugally cast tubes is collected. It is shown that the alloy under investigation is characterized by structural stability, long-term durability, and high-temperature creep resistance up to 1000–1100°С.
