Definitions

  • the invention relates to an austenitic stainless steel for deformation at cold type cold type.
  • Steels that contain a minimum of 11% of chrome are said to be stainless and have good corrosion resistance.
  • Steels austenitic stainless steels also contain nickel, which gives them interesting properties of implementation, especially in cold processing.
  • One of the most commonly used austenitic steels is a steel whose composition is as follows: C ⁇ 0.08, Si ⁇ 1%, Mn ⁇ 2%, S ⁇ 03%, P ⁇ 0.045%, 18 ⁇ Cr20%, 8 ⁇ Ni ⁇ 12%, which lends itself well to cold processing, but is limited in the field of deformation due to its work hardening coefficient relatively high, defining a significant consolidation due to the formation of hardening martensite.
  • Another austenitic stainless steel of the following composition is known: C ⁇ 0.12%; If ⁇ 1%; Mn ⁇ 2%; S ⁇ 0.03%; P ⁇ 0.045%; 17 ⁇ Cr ⁇ 19%; 10 ⁇ Ni ⁇ 13%, which provides a solution to the problem of work hardening due to a relatively high nickel content, which reduces the formation of work hardening martensite.
  • the presence of nickel at these contents also limits the elongation properties of the steel, moreover, this steel is expensive given the high nickel content.
  • Copper acts like nickel by limiting the formation hardening martensite.
  • This higher content copper however, provides good deformability, or even decrease the overall nickel content to around 8%.
  • Such a composition steel is used in particular for cold stamping long steel products stainless.
  • This composition is recommended in particular for striking applications at cold, for which it offers a low work hardening coefficient thanks to very high nickel and manganese contents.
  • document JP 2001011579A presenting the following composition: 0.05% ⁇ C ⁇ 0.5%; 6% ⁇ Mn ⁇ 15%; If ⁇ 0.5%; S ⁇ 0.03%; 10% ⁇ Cr ⁇ 20%; 0.04% ⁇ Ni ⁇ 0.3%; Mo ⁇ 3%; Cu ⁇ 3%; Al ⁇ 0.1%; 0.05% ⁇ N ⁇ 0.3%, whose proportion of nitrogen plus carbon is relatively high as in the composition of the previous document.
  • the invention aims to provide an austenitic stainless steel for cold deformation which can be followed by machining with properties mechanical improvements compared to standard stainless steel austenitics, very interesting properties for transformation applications at cold, and in particular in cold striking,
  • the carbon is controlled at a lower content 0.030% to limit the formation and hardening of martensite hardening. In the same way, and for the same reason, it is necessary to check the sum of the carbon and nitrogen contents to a value lower than 0.07%.
  • the nitrogen content is controlled to a content of between 0.02% ⁇ N ⁇ 0.060% and preferably 0.02% ⁇ N ⁇ 0.04% to stabilize the austenite and guarantee a hot ferrite content ⁇ 15%.
  • the nickel content was lowered between 4.55% and 7% and preferably around 5%.
  • the lowering of the Ni content is compensated by a manganese content of between 5% and 9% and preferably at around 8%.
  • the chromium content guarantees good corrosion resistance, it is chosen between 15% and 18%.
  • Copper is present in the composition to stabilize the austenite. It is limited, as specified in the prior art, to a content of less than 4%. We prefer a content greater than 2% for better stabilization of the austenite.
  • Sulfur is limited to a content of less than 0.01% and preferably to a content of less than 0.002% in order to limit the formation of sulphides of manganese, detrimental to hot processing and to corrosion resistance.
  • the composition also contains molybdenum at a content less than 0.8% and phosphorus at a content less than 0.030%.
  • a composition of a steel 1 according to the invention was compared with a so-called reference, austenitic, standard steel, the compositions of which are presented in Table 1 below: %VS %Yes % Mn %Or % Cr % Mo % Cu %NOT % S Md3 0 % ⁇ Steel 1 0,023 0.36 8.1 5.1 15.0 0.30 3.3 0,035 0,001 - 71.6 Steel Ref 0,029 0.33 1.8 8.1 17.2 0.29 3.2 0,027 0,002 - 59.3
  • the steel according to the invention has good corrosion resistance, comparable to that of standard type 304 steel.
  • steel according to the invention has a non-magnetic character in the annealed state, and weakly magnetic in the hardened state, in weldability, a weldability equivalent to that of a standard type 304 steel and in machinability, machinability similar to that of a standard type 304 steel.
  • the steel of the invention is commercially attractive by using less expensive alloying elements than nickel, and retains a simplicity of implementation works at all stages of its development, in particular thanks to a structure hot and mechanical properties compatible with an elaboration in standard production of standard austenitic stainless steels.
  • the steel of the invention lends itself well to the production of parts comprising a first cold stamping operation followed by finishing machining.
  • the area of its use is potentially, fixation as by example, screws, bolts, nuts, threaded rods, and all special parts implemented by cold stamping, for example, fittings, automotive parts such as fasteners, air bags, support and body probes or parts for mass production connectors such as example, electrical hardware parts.
