摘要： This application relates to a heat transfer tube, its method of manufacture and its use for thermal cracking hydrocarbon feeds, such as thermal cracking in furnaces. The heat transfer tube comprises a chromium and aluminum carburization-resistant alloy capable of generating a typically continuous aluminum oxide scale under thermal cracking conditions that reduces coking and thereby enhances heat transfer. The carburization-resistant alloy comprises 25.1 to 55.0 wt. % nickel; 18.1 to 23.9 wt. % chromium; 4.1 to 7.0 wt. % aluminum; and iron. Additionally, the carburization-resistant alloy has at least one strengthening mechanism to provide desirable mechanical properties. The carburization-resistant alloy composition is also resistant to the formation of cracks during centrifugal casting.
