Definitions

  • the present invention relates to the manufacture of steel parts including less part of the surface is hardened by carburizing or carbonitriding, followed oil or gas quenching.
  • the object of the present invention is to remedy this drawback by proposing a means for manufacturing steel parts of which at least part of the surface is hardened by carburizing or carbonitriding, especially at high temperature.
  • the subject of the invention is a method for manufacturing a steel mechanical part according to which a blank for a steel part is produced and a carburizing or carbonitriding treatment is carried out, in particular at at least high temperature. part of the surface of the blank of the part.
  • the chemical composition of the steel of which the part is made up comprises, by weight: 0.2% ⁇ C ⁇ 0.26% 0.05% ⁇ If ⁇ 0.5% 1% ⁇ Mn ⁇ 1.6%.
  • the chemical composition of the steel is adjusted so that the JOMINY curve of the steel is such that: 45 HRC ⁇ J 3 ⁇ 50 HRC 39 HRC ⁇ J 11 ⁇ 47 HRC 31 HRC ⁇ J 25 ⁇ 40 HRC and so that the average values J 3m , J 11m , J 15m and J 25m of five JOMINY tests are such that:
  • the JOMINY curve is such that at least one of the following conditions is satisfied: 10 x (J 7m - J 11m ) / (4 x (J 15m - J 25m )) ⁇ 2.15 and: 10 x (J 7m - J 15m ) / (8 x (J 15m - J 25m )) ⁇ 2
  • the chemical composition of the steel is such that: 0.21% ⁇ C ⁇ 0.25% 0.1% ⁇ If ⁇ 0.45% 1.1% ⁇ Mn ⁇ 1.5% 0.9% ⁇ Cr ⁇ 1.4% 0.09% ⁇ Mo ⁇ 0.26% 0% ⁇ Ni ⁇ 0.6% 0.005% ⁇ Al ⁇ 0.05% 0% ⁇ Cu ⁇ 0.3% 0% ⁇ Ti ⁇ 0.05% P ⁇ 0.03%
  • the nitrogen content of the steel is between 0.004% and 0.02%.
  • the invention also relates to a case hardening steel whose chemical composition is that which has just been indicated; this case hardening steel having a JOMINY curve such that: 45 HRC ⁇ J 3 ⁇ 50 HRC 39 HRC ⁇ J 11 ⁇ 47 HRC 31 HRC ⁇ J 25 ⁇ 40 HRC the mean values J 3m , J 11m , J 15m and J 25m of five JOMINY tests being such that:
  • the mean values J 7m , J 11m , J 15m and J 25m of five JOMINY tests are such that at least one of the following conditions is satisfied: 10 x (J 7m - J 11m ) / (4 x (J 15m - J 25m )) ⁇ 2.15 and: 10 x (J 7m - J 15
  • the steel may also contain up to 0.02% tellurium, up to 0.04% of selenium, up to 0.07% lead, up to 0.005% calcium, to improve machinability.
  • the rest of the composition is iron and impurities resulting from the development
  • the chemical composition is adjusted so that the JOMINY curve of the steel is such that: 45 HRC ⁇ J 3 ⁇ 50 HRC 39 HRC ⁇ J 11 ⁇ 47 HRC 31 HRC ⁇ J 25 ⁇ 40 HRC and so that the average values J 3m , J 7m , J 11m , J 15m and J 25m of five JOMINY tests are such that:
  • the JOMINY curve is a curve which characterizes the hardenability of the steel. It is obtained by measuring the hardness along a generator of a cylindrical specimen quenched by a jet of water spraying one of its ends. The hardness measured at a distance of x mm from the sprinkled end is called J x . This test is well known to those skilled in the art. However, it has the characteristic of being naturally fairly dispersed.
  • the shape of the JOMINY curve is characterized, here, on the one hand by ranges of value for the points J 3 , J 11 and J 25 , and by the relation:
  • ⁇ 2.5 HRC which involves the means of five different tests, carried out with the same steel. More precisely, 5 identical tests are carried out successively; for each test, we measure at least the values of J 3 , J 7 , J 11 , J 15 and J 25 , we thus obtain five values for J 3 , J 7 , J 11 , J 15 and J 25 , and we calculate for each point J x , the average J xm of the five values.
  • the vertical bars are the symbol known in itself of the absolute value.
  • the relation itself combined with the relation J 3m -J 15m ⁇ 9 HRC or ⁇ 8 HRC, expresses that the JOMINY curve does not show any marked inflection.
  • the desired shape for the JOMINY curve can be refined by requiring that it satisfy at least one of the following relationships: 10 x (J 7m - J 11m ) / (4 x (J 15m - J 25m )) ⁇ 2.15 and: 10 x (J 7m - J 15m ) / (8 x (J 15m - J 25m )) ⁇ 2
  • the copper content remains below 0.3%, the sulfur content is preferably between 0.02% and 0.1%, and it is better that it remains less than 0.09%, the aluminum content is between 0.003% and 0.06%, and it is preferable that it is between 0.005% and 0.05%.
  • the steel may also contain one or more elements taken from tellurium, selenium, lead and calcium.
  • a part according to the invention it is manufactured with a steel according to the invention a blank for a part which is cemented or carbonitrided to high temperature and soak in oil or gas, the oil can be cold, warm or hot.
  • the workpiece blank can be produced, for example, by forging and by machining.
  • parts were produced with six steels according to the invention, the chemical compositions of which were: VS mn Yes S P Or Cr MB Cu al AT 0.23 1.25 0.27 0,028 0,018 0.2 1.15 0.1 0.14 0,028 B 0.24 1.4 0.4 0.05 0.02 0.25 1.0 0.24 0.25 0.04 VS 0.21 1.35 0.15 0.07 0,025 0.35 1.25 0.18 0.2 0.01 D 0.21 1.27 0.25 0.03 0.02 0.21 1.12 0.2 0.14 0.005 E 0.23 1.27 0.27 0.031 0.014 0.197 1.1 0.214 0,137 0.016 F 0.23 1.10 0.25 0.03 0,015 0.15 1.3 0.15 0.12 0.016
  • case hardening After case hardening at 995 ° C for 10 hours and quenching in warm oil at 98 ° C, the parts did not show deformations requiring machining additional. In addition, case hardening was characterized by a content of 0.94% carbon 0.1 mm below the surface.
