ASTM B408 Incoloy 800H Round Bar Manufacturer, Supplier, Stockist & Exporter

The creep rupture durability of Incoloy 800H/HT is higher than that of other alloys.  With a low carbon content and small additions of aluminum and titanium, the alloy exhibits excellent performance over a wide temperature range.

Alloy 800H is an iron-nickel-chromium alloy with the same basic composition as Alloy 800, but with a significantly higher creep rupture strength. High temperature annealing and close control of the carbon, aluminum, and titanium contents result in higher strength. To optimize stress rupture properties, the 800H modification was to control carbon (0.05 to 0.10%) and grain size (>ASTM 5). In order to ensure optimum high temperature properties, 800HT has further modified titanium and aluminum levels (0.85 to 1.2%). The alloy is dual certified and offers properties of both forms.

As a result of its chemical balance, the alloy exhibits excellent resistance to carburization, oxidation, and nitriding. Even after long periods of usage in the 1200-1600 degree F range where many stainless steels become brittle, 800HT will not be affected. 800H exhibits excellent cold forming properties typically associated with nickel-chromium alloys. When cold formed extensively the grain size produces a visibly undulated surface called “orange peel”. 800H can be welded by the common techniques used on stainless steels.

Typical applications of the alloy include ethylene pyrolysis, hydrocarbon cracking, and cracking furnaces for vinyl chloride, diphenol, and acetic acid. The alloy is also used for valves, fittings, and other components exposed to corrosive attack between 1100 and 1800 deg F. Round bars range from 3/4″ to 6″ in diameter, as well as light gauge sheets and plates. The material can be supplied in random lengths, cut to order, or machined to customer specifications. Machining includes drilling, threading, milling, CNC shapes, turning, tapping, flanges, and so on.

Generally, Incoloy DIN 1.4958 Bars have the same chemical composition as Incoloy 800H Bars, with some variations in their aluminium, titanium, and carbon levels. measure. These Incoloy 800H Bright Bar are accessible to our valuable customers in different range of diameters, wall thicknesses and sizes in customized form and also at quite affordable rates

Astm B408 Incoloy 800h/800ht Bright steel Bar are usually carbon steel alloys that have had their surface condition improved by drawing, peeling, or grinding after the hot rolled finish supplied by the steel mill. Among the advantages are improved machining, reduced waste at the component production stage, improved physical and mechanical properties, and better dimensional tolerances and straightness.

Incoloy 800h/800ht Cold drawn bars are widely used in mass production due to their excellent mechanical and dimensional properties and superior machining characteristics compared to hot rolled bars. Cold drawn bars are available in round, hexagonal, and square shapes.

Alloys with high nickel content, such as Inconel 800H Bar, are more corrosion resistant against many organic and inorganic compounds. Alloy 800 Nickel Hot Rolled Bar is also practically immune to chloride-ion stress induced corrosion cracking due to nickel content. Alloy 800H Inconel Polished Bars containing chrome and nickel are more resistant to sulfur-containing compounds as well as oxidation resistance at high temperatures or in the presence of corrosive solutions.
