Definitions
- the invention relates to a wrought nickel alloy with the alloy components C, Si, Mn, Cr, Mo, Cu, Ti and Fe with the aim of making a substantial increase in strength possible by a special heat treatment by changing the percentage composition.
- This alloy is generally used in the solution-annealed state, whereby (the mechanical characteristics refer to RT in the following) a tensile strength of about 600 to max. 700 N / mm 2 and a 0.2% proof stress from about 230 to max. 270 N / mm 2 .
- the work hardened condition is also common for pipes and rods, with the work hardening achieved being of the order of magnitude as is the case for austenitic Cr-Ni steels; the tensile strength is accordingly for cold-formed pipes up to about 800 N / mm 2 and the 0.2% proof stress up to about 500 N / mm 2 .
- Such an alloy also has a permeability below 1.010, with which it can be described as non-magnetic.
- the wrought alloy according to the invention also up to 0.7%, preferably up to 0.5% Al and / or 0.3 to 1, 2%, preferably 0.5 to 1.2% Nb / Ta.
- the invention also includes the heat-treated alloy.
- a preferred method for the heat treatment of this wrought nickel alloy is characterized in that after solution annealing in the temperature range from 980-1170 ° C. with a holding time of at least 5 minutes in order to achieve a further increase in strength, the temperature is preferably set to 650-800 ° C. 680 - 770 ° C, is carried out for a period of 3 to 20 h, preferably from 6 to 16 h.
- a further increase in these mechanical parameters can still be achieved in that, after solution annealing, a cold deformation with a degree of deformation of 5 to 15% is interposed.
- the strength-increasing effect of the heat treatment is improved because an even finer distribution of the particles separated out at the grain boundaries is thereby achieved. While in this case cooling to room temperature is mandatory after solution annealing, the strength-increasing heating can also be carried out without such cooling, that is, directly from the temperature range of solution annealing.
- the invention further relates to the use of the alloy as a material for non-magnetic parts, such as housing parts, etc. Bohrstan g fleeth., Particularly for opening up and / or extracting gaseous and / or liquid fossil fuels. It was quite surprising that with the increased addition of titanium, in addition to the possible increase in strength values, a permeability is also achieved which allows this material to be used for such components, while the low susceptibility to stress corrosion cracking makes this material suitable for use in drilling and conveyor technology, for example as non-magnetic collars or as a housing for corresponding magnetic measuring devices and the like, is outstandingly suitable.
- melt no. 1 the composition of eleven test melts is compared to that of melt no. 1, the alloys according to the invention, beginning with melt no. 2, differing in particular from an increasing titanium content.
- the permeability decreases with increasing titanium content, the permeability coming below approximately 1.01 from a titanium content of 1.2%, so that here there is a material that can be technically designated as non-magnetic.
