HY Titanium 6-4 ELI Material grades and equivalents
6-4 ELI Titanium, 6-4 ELI, UNS R56401
Introduction
Low interstitial version of HY Titanium 6-4 ELI, for maximum toughness. Preferred for marine and cryogenic applications. This grade is normally used in the annealed condition. HY Titanium 6-4 ELI is the preferred choice for the medical implant field.
Stress relief 900-1200°F 1 to 4 hours, air cool. Duplex anneal, bar and forgings: Solution anneal 50-100°F below the beta transus, hold 1 hour minimum, air cool. Then reheat within the range 1300-1400°F, hold 1 hour minimum, air cool. Stress – relief annealing is performed after welding.

How to weld nickel alloys like hastelloy, inconel, etc. Nickel alloys have a low thermal conductivity and so limiting heat input and using lower amperage than would be used for stainless is one key to making good nickel alloy welds.
Experimentální odlévání monelu na katedře strojírenské technologie při TU v Liberci – Monel je slitina niklu a mědi. Název Monel je registrován jako trademark americké firmy Specific Metals Corporation. Monel vyrobil v roce 1901 Robert Crooks Stanley, slitinu pojmenoval po tehdejším prezidentu firmy Ambrose Monellovi.
Monel vykazuje výborné mechanické vlastnosti a chemickou odolnost v náročném prostředí, např. v dlouhodobém kontaktu se slanou vodou, ale i v chemickém průmyslu. Často bývá využit tam, kde již nedostačují vlastnosti nerezových ocelí.
Monel is a group of nickel alloys, largely composed of nickel (up to sixty seven%) and copper, with tiny quantities of iron, manganese, carbon, and silicon. More powerful than pure nickel, Monel alloys are resistant to corrosion by quite a few agents, like promptly flowing seawater. They can be fabricated quickly by very hot- and chilly-working, machining, and welding.[2]
Monel was made by David H. Browne, main metallurgist for Global Nickel Co. Monel alloy four hundred is a binary alloy of the identical proportions of nickel and copper as is found naturally in the nickel ore from the Sudbury (Ontario) mines and is thus thought of a puritan alloy. Monel was named following business president Ambrose Monell, and patented in 1906.[three] Just one L was dropped, for the reason that loved ones names were being not allowed as trademarks at that time.[one] The title is now a trademark of Specific Metals Corporation.
