Definitions

  • the present invention relates to a weldable austenitic stainless steel, with high machinability and having good cold deformation characteristics.
  • JP-A-160 785 discloses a machinable steel, cold deformable and having in its weight composition, in particular a sulfur content of less than 0.03%, calcium and oxygen contents of between 10 and 300 ppm and between 30 and 300 ppm, a copper content between 0.8 and 5% and a lead content between 0.01 and 0.25%.
  • the improvement in machinability is generated by the introduction into the composition of a variable amount of lead.
  • austenitic stainless steels are difficult to machine, on the one hand, because of their low thermal conductivity and, on the other hand, because of their high work hardening locally inducing zones of high hardness. Poor flow of the heat produced at the tip of a cutting tool leads to rapid deterioration of the tool.
  • This element has the disadvantages of being difficult to dissolve homogeneously in a molten bath and, because of its high density, of having a tendency to accumulate in the bottom of metallurgical vessels.
  • boron can be introduced into the composition of austenitic stainless steel according to JP-A-160 785, as an element capable of counteracting the harmful effects of lead in the field of hot rolling, but the boron increases still the welding difficulties.
  • the introduction of the boron element also brings at least one other drawback, that of reducing the temperature range suitable for hot rolling, which imposes a more restrictive hot rolling process.
  • Austenitic stainless steel according to JP-A-160 785 may also contain titanium.
  • titanium which is generally introduced into stainless steels in order to improve the resistance to intragranular corrosion, disrupts the formation of calcium oxide inclusions and reduces their number.
  • titanium leads to the formation of hard inclusions which reduce the machinability by promoting premature wear of the cutting tools.
  • Also known from FR-A-2 542 761 is a process for manufacturing a steel with high machinability.
  • a cause of the difficulty in machining stainless steels lies in the fact that they contain inclusions of hard oxides such as for example alumina or chromite which deteriorate the cutting tools.
  • One way of reducing the harmfulness of hard oxide inclusions is to introduce one or more alkaline earth compounds into the steel, in order to replace a good proportion of hard inclusions with calcium-based oxide inclusions, for example. It is also specified, on the one hand, that a certain quantity of sulfur combined with hard inclusions reduces its harmfulness, the sulfur content generally being less than 0.5 ⁇ 10 -4 % and, on the other hand, that another way to reduce the harmfulness of inclusions is to reduce their quantity thanks to good deoxidation and good settling of the bath during the production of steel.
  • the aim sought is the formation, with manganese and in a smaller proportion with chromium, of a manganese sulfide and chromium (Mn, Cr) S which generates in the form of specific inclusions a solid lubrication of the cutting tool during machining operations.
  • sulfur has an unfavorable effect on the corrosion resistance and that despite this a chosen orientation is the introduction into a resulfurized steel of oxides of lime silicoaluminate and preferably of anorthite.
  • the subject of the present invention is a weldable austenitic stainless steel, with improved machinability and having good cold characteristics, in which the simultaneous presence in suitable proportion, of copper and of malleable oxides, chosen in a ternary diagram A1 2 0 3 , Si0 2 , CaO, significantly improves a set of properties, some of which are contradictory.
  • the weldable austenitic stainless steel contains malleable oxides whose compositions are located in the ternary diagram AL 2 0 3 , Si0 2 and CaO, in the zone of the triple point anorthite, gehlenite, pseudo-wollastonite.
  • the sulfur ensures the formation of micro-precipitates of manganese sulphide and the copper ensures a reduction of the work hardness allowing to obtain a less hard surface and, during the machining, to form chips also less hard at the temperature d 'machining hence a significant increase in the life of the tools.
  • the nitrogen concentration is between 0.03 and 0.05%.
  • the carbon concentration is less than 0.03%
  • the Ca / O ratio being between 0.3 and 0.6.
  • This steel contains malleable oxides whose compositions are located on the ternary diagram AL 2 0 a -Si0 2 -CaO, in the zone of the triple point anorthite, gehlenite and pseudo-wollastonite.
  • the nitrogen element introduced into the composition of austenitic stainless steels in a determined and limited proportion between 0.03 and 0.05% stabilizes the austenite at the expense of the formation of hardening martensite which tends to reduce the magnetic permeability .
  • the carbon concentration is less than 0.03%.
  • the copper element replacing sulfur and lead used alone and preferably with nitrogen, contributes to the stabilization of the austenite at the expense of the formation of the martensite for work hardening which results by a consequent reduction in magnetic permeability.
  • the austenitic stainless steel according to the invention has a set of sometimes surprising, sometimes contradictory physical characteristics and properties, such as machining, welding, cold deformation, non-magnetism and corrosion resistance.
  • This reference steel is an austenitic steel referenced, the general composition of which is as follows: C less than 0.08%, Cr between 18 and 20%, Ni between 8 and 10.5%, S less than 0.03 %, Mo less than or equal to 0.5%, Nn less than or equal to 2% and N less than or equal to 0.1%.
  • the steel according to the invention has also been tested in "Gun Drilling" technology, that is to say in drilling with a guide gun and under high pressure oil.
  • the choice of cutting conditions for good chip evacuation being ensured, the machining of steel parts according to the invention is four times faster than with a reference steel and the number of parts machined before resharpening the tool is 6 times higher.
  • the steel according to the invention has a magnetic permeability of 1.4 (Curve G, Fig. 3) and only 1.9% of martensite is formed during wire drawing ( Curve E, Fig. 4).
  • the reference steel forms three times more martensite (curve F - Fig. 4) and therefore has a magnetic permeability of 2.4 (curve H - Fig. 3).
  • the passivation pH measured in a sodium chloride solution and defined by the pH above which the critical passivation current is less than 1 OwA / cm2, is substantially equal to 3 with the steel according to the invention (curve J) and significantly lower than that of the reference steel which is 3.5 (curve K).
  • This area was compared with a non-heat affected area and found that this non-heat affected area includes the known sulfide inclusions of such resulfurized steel.
  • the steel according to the invention is suitable for high speed machining, cold deformability with remarkable magnetic properties and high resistance to cavernous corrosion as well as welding ability.
