Threaded rods are also, generally referred to as studbolts or connectors. Upon your request we can manufacture Incoloy 800H/HT threaded rods of the dimensions exactly according to your requirements. These may for example include threaded rods according to DIN 976 and other dimensions or tolerances of the thread in various sizes, lengths and from various materials. We are producing the Incoloy rods by thread rolling. Rolled threads has main benefits such as the increase of strength by means of cold forming, very good surface roughness values, high dimensional accuracy and many others.

Metline is a full line manufacturer of Incoloy 800H/HT threaded bars in accordance with DIN, ASME, ASTM and ISO standards. The most commonly used Incoloy Alloys for manufacturing threaded bars and rods are Incoloy 800, Incoloy 800H and Incoloy Alloy 800HT.

Metline is a professional manufacturer and supplier of Incoloy 800HT threaded bars/rods with nuts and washers. We offer hot forged Incoloy threaded bars and nuts up to 2″ Dia, and custom length. Our CNC machined Incoloy threaded rods can be offered in sizes upto M100 / 4” Dia in custom lengths.

Incoloy 800,Incoloy 800H , and Incoloy 800HT are nickel-iron-chromium super alloys. When exposed to high-temperature these alloys not only provide excellent resistance to oxidation and carburization but also good strength too. These nickel steel alloys are similar except for the higher level of carbon in Incoloy 800H, and the addition of up to 1.20 percent titanium and aluminum in Incoloy 800HT.
