Definitions

  • the present invention relates to an abrasion-resistant steel and its method of manufacture.
  • High abrasion resistant steels with a hardness of about 600 Brinell are known. These steels contain from 0.4% to 0.6% of carbon and from 0.5% to 3% of at least one alloying element such as manganese, nickel, chromium and molybdenum and are soaked to have a completely martensitic structure. But these steels are very difficult to weld and cut. To overcome these drawbacks, it has been proposed, especially in EP 0 739 993, to use for the same uses, a less hard steel, whose carbon content is about 0.27% and having a quenched structure containing a significant amount of residual austenite. But these steels are still difficult to weld or cut.
  • the object of the present invention is to overcome these disadvantages, by proposing an abrasion-resistant steel sheet whose abrasion resistance is comparable to that of known steels but whose weldability and thermal cutting ability is better.
  • the subject of the invention is a method for manufacturing a part, and in particular a sheet, made of steel for abrasion, the chemical composition of which comprises, by weight:
  • Nb optionally at least one element selected from Nb, Ta and V in contents such that Nb / 2 + Ta / 4 + V ⁇ 0.5%
  • quenching may be followed by tempering at a temperature below 350 ° C, and preferably below 250 ° C.
  • the invention also relates to a sheet obtained in particular by this method, the steel having a martensitic or martensito-bainitic structure, said structure containing from 5% to 20% retained austenite, as well as carbides.
  • the thickness of the sheet may be between 2 mm and 150 mm and its flatness is characterized by an arrow less than or equal to 12 mm / m and preferably less than 5 mm / m.
  • the carbon content is less than 0.325%, and more preferably less than 0.3%.
  • Ti + Zr / 2 must be greater than 0.35% and preferably greater than 0.4%, and more preferably greater than 0.5%, so as to form a large amount of large carbides. However, this sum must remain less than 1.1% so as to keep enough carbon in solution in the matrix after formation of carbides. Preferably this sum must remain less than 1%, and better still 0.9% and better still less than 0.7% if one needs to favor the tenacity of the material.
  • the titanium content should preferably remain less than 1%, and more preferably less than 0.9%, or even less than 0.7%, and the zirconium content should preferably remain below 2%, and better less than 1, 8%, or even less than 1, 4%.
  • the boron content should preferably be greater than 0.0005% or better 0.001%, and need not exceed substantially 0.01%.
  • - Up to 0.15% sulfur This element is a residual usually limited to 0.005% or less, but its content can be voluntarily increased to improve machinability. It should be noted that in the presence of sulfur, in order to avoid difficulties of hot transformation, the manganese content must be greater than 7 times the sulfur content.
  • Nb / 2 + Ta / 4 + V remains less than 0.5% in order to form relatively large carbides which improve the resistance to abrasion.
  • the carbides formed by these elements are less effective than those formed by titanium or zirconium, that is why they are optional and added in limited quantities.
  • titanium and zirconium can be added to the liquid steel in a very gradual manner, for example by contacting the oxidized liquid steel with an oxidized phase such as a slag loaded with oxides of titanium or zirconium, then deoxidizing the liquid steel, so as to slowly diffuse titanium or zirconium from the oxidized phase to the liquid steel.
  • an oxidized phase such as a slag loaded with oxides of titanium or zirconium
  • the carbon, titanium, zirconium and nitrogen contents must be such that: C - Ti / 4 - Zr / 8 + 7xN / 8> 0.095%
  • C * represents the free carbon content after precipitation of the titanium and zirconium carbides, taking into account the formation of titanium and zirconium nitrides.
  • This free carbon content C * must be greater than 0.095%, and preferably> 0.12%, to have a martensite having a minimum hardness. The lower this content, the better the welding and thermal cutting ability.
  • the chemical composition must be chosen so that the quenchability of the steel is sufficient, given the thickness of the sheet that is to be manufactured.
  • the micrographic structure of the steel consists of martensite or bainite or a mixture of these two structures, and from 5% to 20% retained austenite.
  • This structure further comprises large titanium or zirconium carbides formed at high temperature, or even carbides of niobium, tantalum or vanadium. The inventors have found that the effectiveness of large carbides for improving the abrasion resistance could be obelated by the premature loosening thereof and that this loosening could be avoided by the presence of metastable austenite which is transformed under the effect of abrasion phenomena.
  • the slab or slug is hot rolled to obtain a sheet that is submitted to a heat treatment allowing at the same time to obtain the desired structure and a good flatness without subsequent planing or with limited planing.
  • the heat treatment can be carried out directly in the hot rolling or carried out later, and possibly after a cold planing or half-hot.
  • slightly lower is meant a temperature between T and T - 50 ° C, or better still between T and T - 25 ° C, or better still, between T and T - 10 ° C.
  • the sheet is cooled to a mean core cooling rate Vr of between 0.1 ° C./sec, to obtain a sufficient hardness, and 1150xep "1, 7 , to obtain the desired structure,
  • the sheet is cooled to room temperature, preferably, but not necessarily, at a slow speed.
  • an expansion treatment such as tempering, can be carried out at a temperature of less than or equal to 350 ° C, and preferably less than 250 ° C.
  • steel sheets identified A to C according to the invention and D to E according to the prior art were produced.
  • the chemical compositions of the steel, expressed as 10 "3 wt%, and the hardness and an index of wear resistance Rus, are reported in Table 1.
  • the wear resistance was measured by weight loss of a prismatic test tube rotated in a tank containing calibrated granules of quartzite for 5 hours.
  • the Rus index of a steel is equal to 100 times the ratio of the wear resistance of the steel in question and the wear resistance of a reference steel (steel D).
  • All sheets are 27 mm thick and are hardened after austenitization at 900 ° C.
  • the average cooling rate is 7 ° C / s above the temperature T defined above, and 1 6 ° C / s below, in accordance with 'invention
  • the average cooling rate is 0.8 ° C / s above the temperature T defined above, and 0.15 ° C / s below, according to the invention
  • the steel sheets D and E, given for comparison were cooled at an average speed of 24 ° C / s above the temperature T defined above, and at an average speed of 12 ° C / s below .
  • the comparison of the wear resistances and the hardnesses shows that, although being very substantially less hard than the sheets given for comparison, the sheets according to the invention have a slightly better resistance to wear.
  • the comparison of the free carbons shows that the good abrasion resistance of the sheets according to the invention is obtained with very significantly lower free carbons, which leads to significantly better welding or thermal cutting abilities than for the sheets according to the invention. the prior art.
  • the deformation after cooling, without planing, for steels according to the invention A to C is about 5 mm / m and 16 mm / m for steels D and E given for comparison.
