A nickel alloy includes (in wt. %) Ni 50-55%, Cr 17-21%, Mo>0-9%, W 0-9%, Nb 1-5.7%, Ta>0-4.7%, Ti 0.1-3.0%, Al 0.4-4.0%, Co max. 3.0%, Mn max. 0.35%, Si max. 0.35%, Cu max. 0.23%, C 0.001-0.045%, S max. 0.01%, P 0.001-0.02%, B 0.001-0.01%, the remainder Fe and the conventional process-related impurities, wherein the following relations are provided: Nb+Ta 1-5.7% (1), Al+Ti>1.2-5% (2), Mo+W 3-9% (3), where Nb, Ta, Al and Ti are the concentration of the elements in question in wt. %.

Nickel alloy having good resistance to corrosion and high tensile strength, and method for producing semi-finished products

Nickel-cobalt alloy for powder, wherein the contents (in wt %) are defined as follows:

Powder consisting of a nickel-cobalt alloy, and method for producing the powder

A roll-bonded clad metal sheet and a method for producing a roll-bonded clad metal sheet is provided. The roll-bonded clad sheet includes a metallic base material layer and a metallic cladding material layer which are joined to one another by a metallurgical bond. The metallic cladding material layer includes a nickel-based material whose chemical composition includes, in % by mass, a proportion of more than 50% of Ni and a proportion of 3.1% of Nb. The metallurgical bond is obtained by a thermomechanical rolling process including a first rolling phase for prerolling, a second rolling phase for final forming and a cooling time between the first rolling phase and the second rolling phase, wherein a final rolling temperature of the second rolling phase is set to a value equal to or less than 880&#xb0; C.

Method for producing roll-bonded metal sheets

In a method for preparing a nickel-based alloy, an electrode is produced by VIM, VOF or VLF, heat-treated in a furnace between 500 and 1300&#xb0; C. for 10 to 336 hours to reduce stresses and aging, the heat-treatment being conducted for at least 10 hours and at most 48 hours at 1000&#xb0; C. to 1300&#xb0; C., and cooled to between room temperature and less than 900&#xb0; C., then remelted using ESR at 3.0 to 10 kg/minute to form an ESR block which is cooled to between room temperature and less than 900&#xb0; C., and remelted again using VAR at 3.0 to 10 kg/minute and a remelting rate fluctuation range of less than 15%, preferably 10%, ideally 5%; the remelted VAR block is heat-treated between 500 and 1250&#xb0; C. for 10 to 336 hours, then shaped into the desired product shape and dimension by hot or cold forming.
