Incloloy840 800 825 Inconel600 625 Nickel Alloy Welded Electric Heating Tubes and Pipe
Product Description:
Alloy 800, 800H, and 800HT are nickel-iron-chromium alloys with good strength and excellent resistance to oxidation and carburization in high-temperature exposure. These nickel steel alloys are identical except for the higher level of carbon in alloy 800H/HT and the addition of up to 1.20 percent aluminium and titanium in alloy 800HT. Alloy 800 was the first of these alloys and it was slightly modified into Alloy 800H. This modification was to control carbon (.05-.10%) and grain size to optimize stress rupture properties.
In heat treatment applications Alloy 800HT has further modifications to the combined titanium and aluminium levels (.85-1.20%) to ensure optimum high temperature properties. Alloy 800H/HT was intended for high temperature structural applications. The nickel content makes the alloys highly resistant to both carborisation and to embrittlement from precipitation of sigma phase.
Nickel is a chemical element with symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel belongs to the transition metals and is hard and ductile. Pure nickel, powdered to maximize the reactive surface area, shows a significant chemical activity.
