INCONEL 693

没有此类产品
产品描述
A nickel-chromium-aluminum alloy offering the best resistance to metal dusting of any available conventional alloy. Alloy 693 also offers exceptional resistance to oxidation and carburization at temperatures up to 2100°F (1150°C) with excursions to even higher temperatures. The alloy’s ability to resist metal dusting is especially useful in systems used to reform hydrogen and generate synthesis gas for various industries, including gas and liquid fuel production. Alloy 693 is protected by U.S. Patent Number 4,882,125.
STANDARD PRODUCT FORMS
Plate, sheet, strip, bar, seamless tubes and pipes.
