Definitions
- the invention relates to a curable
- Very good corrosion resistance means that the alloy and parts made from it can be exposed to solutions containing CO 2 , H 2 S, chlorides and free sulfur at temperatures between room temperature and 350 ° C and pressures between 10 and 100 bar.
- Corrosion resistance or they contain niobium as essential for hardening
- a hardenable nickel alloy which is characterized by 43 to 51% nickel 19 to 24% chromium 4.5 to 7.5% molybdenum 0.4 to 2.5% copper to 1% manganese to 0.5 % Silicon to 0.02% carbon to 2% cobalt 0.3 to 1.8% aluminum 0.9 to 2.2% titanium balance iron, including unavoidable, manufacturing-related impurities.
- the nickel alloy according to the invention is suitable as
- a restricted composition which is characterized by particularly good processing properties, is characterized by
- the nickel alloy is particularly suitable as a material for the production of components that are to be used under very aggressive sour gas conditions. In the manufacture of components that have sufficient corrosion resistance under very aggressive
- Cast blocks were made, the cast blocks were homogenized at 1220 ° C and then thermoformed above 1000 ° C and the parts obtained were quenched in water, and the thermoformed and quenched parts were cured at 650 to 750 ° C for 4 to 16 hours and then subjected to air cooling.
- the following alloy is preferably used for casting blocks which are said to have particularly good processing properties 46 to 51% nickel,
- titanium 1.5 to 2.1% titanium, balance iron, including unavoidable, manufacturing-related impurities used.
- the mechanical-technological properties can be further improved by additional curing steps.
- the thermoformed and quenched parts are first annealed for 4 to 10 hours at 700 ° C to 750 ° C, then cooled in an oven at 5 to 25 ° C per hour by 150 ° C and then placed in air.
- the components can also be kept between 730 ° C to 750 ° C for 30 minutes, then cooled in an oven at 5 to 25 ° C per hour to 700 ° C and then at 2 to 15 ° C per hour to 580 ° C. Finally, the components are placed in air.
- thermoformed parts are subjected to solution heat treatment at 1150 to 1190 ° C. before being quenched in water.
- the thermoformed, solution-annealed and water-quenched parts can also be kept at 700 to 750 ° C for 4 to 10 hours, then in the furnace at 5 to 25 ° C per hour by 150 ° C and finally further cooled in air. Further details and advantages of the inventive concept are explained in more detail on the basis of the following test results.
- Table 1 shows the chemical composition of 7 alloys, which - after different heat treatment - have been examined for their mechanical properties at room temperature (RT) and at 260 ° C. The results are summarized in Tables 2 to 7.
- results show that the required minimum mechanical properties were achieved in all cases and in some cases considerably exceeded. Furthermore, it can be seen from the results as a whole that with the different variants of the heat treatment, different values of the mechanical properties can be achieved, which can be advantageous for the adjustment to special requirement profiles. In favor of higher elongation at break values, for example, maximum strength values can be dispensed with and vice versa. Apart from this general tendency, it can also be seen that the highest strength values are achieved if the thermoformed parts are not solution annealed again, but are directly quenched in water and that the maximum achievable strength depends on the total aluminum plus titanium content.
- the aluminum and titanium contents cannot be increased arbitrarily, because disadvantageous elimination phases then occur which cannot be avoided or compensated for even in the case of complex heat treatment.
- the numerous alternatives in the heat treatment it is always possible to achieve optimum strength values in each case without having to put up with disadvantageous structural structures. For example, the more complex three-stage curing treatment will be indicated when it comes to avoiding a reduction in the impact strength when setting the highest possible strength values.
- Solution A 25% NaCl, 10 bar H 2 S and 50 bar CO 2 solution B: 25% NaCl, 0.5% acetic acid, 1 g / l sulfur and 12 bar H 2 S.
- the alloy according to the invention accordingly shows in a new way a combination of high strength that has not been achieved with curable materials and at the same time excellent resistance in very aggressive acid gas media.
