CENTRALLOY®60 HT: A high performance material withstands loads at tube wall temperatures of up to 1,200 ºC
Schmidt+Clemens GmbH + Co. KG, the world’s leading manufacturer of high-quality stainless steel system components, has developed a unique new material for high-temperature conditions, in cooperation with several prestigious research institutions. The patented high-performance material CENTRALLOY® 60 HT withstands greatly fluctuating mechanical loads as well as corrosion even at ultra-high tube wall temperatures of 1,200 ºC.
To date, the chemical industry has been using centrifugally cast pipe made of FeCrNi alloys in industrial-scale ethylene cracking reactors. These materials reliably shield themselves against oxidation and carburization through formation of a protective chromium oxide layer at temperatures of up to 1,100 ºC. Due to the higher aluminum content and other additive elements, CENTRALLOY® 60 HT demonstrates superior oxidation, carburization and creep characteristics, and is an excellent choice for centrifugally-cast pipes and finish-cast parts with higher carbon contents.
Schmidt+Clemens has already tested the new material in practical trials in a number of industrial applications, including ethylene crackers, furnace tables, rotary furnace tubes and hardening shops. CENTRALLOY® 60 HT is suitable for use in ethylene cracking furnaces, as well as in the areas of direct reduction of iron ore and methanol extraction plants. This high-performance material can also be used in building industrial furnaces for steel works as well as in ceramics and glass production. “CENTRALLOY® 60 HT demonstrates excellent properties in laboratory experiments and promises longer service lives for components that are subject to extreme loads,” says Gerhard Völkner, CEO of Schmidt+Clemens. “The market has a clear need for a high-performance material like CENTRALLOY® 60 HT, which is evident not least in the fact that we are receiving inquiries daily.”
Due to the high alloy and the special requirements for mechanical processing, components made of CENTRALLOY® 60 HT are initially comparatively more expensive. But when higher application temperatures, reduced maintenance costs and the longer service life of the material are taken into consideration, this technical innovation promises improved economic performance.
