Alpha Overseas is a leading manufacturer and trader of Alloy 800 / 800H / 800HT Fasteners, which are meant to control carbon and grain size for to optimize stress rupture properties. Inconel 800 Fasteners has high demand among our clients all across the globe, which is sourced from our reliable experts who manufacture them from high grade material. Inconel 800H Fasteners is stereotypically used for uses involving enduring exposure to high-heats where resistance is required from carburization, rust and other categories of high-heat corrosion. Inconel 800HT Fasteners has good creep-rupture properties at temperatures above 1100 Degree F (600 Degree C). Alloy 800 Fasteners has further reforms to the united titanium & aluminium stages to ensure best possible high heat properties. Alloy 800H Fasteners is extremely resistant to corrosion, even in acidic environment. Alloy 800HT Fasteners is a solution temperature treated (2100 Degree F / 1150 Degree C), measured-carbon kind of alloy with enriched elevated heat properties. Incoloy 800 Fasteners has many different industrial applications, some of which include: Heat exchangers, Industrial furnaces, Hydrocarbon cracking and so on.
