Definitions
- drill stems are usually made from heattreated steel, mainly from molybdenum-chromium alloy steels as well as of nickel-chromium low alloy steels.
- the drill stems being subjected during operation to high stresses, which may arise in various cases in a complex form, which cannot be foreseen, the quality of the manufacture regarding the selection of the material and regarding the processing is of high importance. For this reason, drill stems are continually subjected to checks during manufacture and it is highly decisive how the material which is used responds to all machining operations, mainly to being drilled.
- Drill stems of these Monel-K alloys have proved entirely non-magnetic in use and have also the necessary mechanical characteristics, particularly a high yield point, and can be economically machined, particularly as regards the drilling of the drill stems.
- austenitic alloys steels are also non-magnetizable and it has been known for a long time to improve the lower strength of such steels, particularly regarding the yield point, by cold working or bya precipitation hardening treatment, if desired, it has not been proposed before to use such austenitic steels for drill stems.
- the previous failure to consider austenitic alloy steels as materials for making drill stems appears to be mainly due to the fact that it has not been possible before to provide steel compositions which in addition to being reliably non-magnetizable and having a high strength have also the essential machinability and, particularly, can be economically machined by drilling to form the hole in drill stems of considerable length after cold working.
- the invention provides a method of manufacturing drill stems for deep-well drill rods from non-magnetizable austenitic manganese-chromium steels, in which manganese-chromium steels containing up to 0.35% carbon, up to about 1% silicon, 12-25% manganese, 1020% chromium, up to about 5% nickel, up to about 1% molybdenum and 0.0-50.50% nitrogen, balance iron with the usual accompanying elements, are cold-worked to raise the yield point to kg./ sq. mm. and higher at least adjacent to the ends.
- These steels may desirably have the additions usual in such alloy steels, such as up to 1.5% tungsten, up to 1% titanium, up to 2% columbiumand/or tantalum, up to 0.5% boron, up to 1.5% vanadium, up to 3% copper and up to 5% cobalt, individually or jointly, in a total amount not exceeding 10%.
- steels containing up to 0.12% carbon, up to 0.60% silicon, 17-19% manganese, 11.50-l3% chromium, 1.52% nickel, GAO-0.60% molybdenum, 0.100.15% nitrogen, balance iron with the usual accompanying elements, have proved particularly suitable.
- the austenitic steels proposed according to the invention it has surprisingly been found that they can be machined, particularly by drilling to form the hole, in spite of their relatively high strength with the dimensional accuracy required particularly for drill stems and that the bores of the drill stems having lengths up to about 10 metres are entirely satisfactory. It is known that the drilling of the drill stems involves great difii culties and that a high precision of the machine tools is required. Deviations of the bore from the center of the stem may result in dangerous reductions in wall thickness and must be absolutely avoided. This aspect is of essential significance in the evaluation of the machinability (drillability).
- the strength values of the nonmagnetic alloy steels proposed according to the invention as material for drill stems are virtually similar to those of the usual heat-treated magnetic molybdenum-chromium steels when the same are used after being normalized throughout their length and with heat-treated ends.
- a dr-ill stem of nonmagnetic steel alloy for a deep-well drill pipe comprising an alloy steel consisting essentially of 0.01 to 0.25% by weight carbon, 0.10 to 1.00% by weight silicon, 12.00 to 25.00% by weight manganese, 10.00 to 20.00% by weight chromium, 0.05 to 0.50% by weight nitrogen, up to 5.00% by weight nickel, and up to 1.00% by weight molybdenum, the balance being es- 4 sentially iron; said alloy steel being cold worked at least along a portion of the drill stem to a yield point of about 70 kg./mm.
