Definitions

  • the invention relates to the use of an austenitic stainless steel for hydrogen technology in motor vehicles with high resistance to hydrogen-induced embrittlement, in particular in the temperature range between -100 ° C and room temperature (+ 25 ° C). It is suitable for all hydrogen in contact with metallic components of a motor vehicle, such as hydrogen tanks, valves, pipes, fittings, Boss, liner springs, heat exchangers or bellows.
  • US 2009/0159602 A1 is an austenitic steel having a composition according to the formula - 120 ⁇ Md 30 ⁇ 20 with Md30 (° C): 551-462 (C + N) -9.2Si-8, lMn-13.7Cr-29 (Ni + Cu) -18.2Mo.
  • the object of the invention is to provide for use for the hydrogen technology in motor vehicles, a cost-effective steel that is resistant to hydrogen-induced embrittlement throughout the temperature range between at least + 100 ° C and -253 ° C and high pressure resistant, has corrosion resistance and good warm and cold forming and welding.
  • the melting-related steel accompanying elements comprise further customary production-related elements (eg sulfur and phosphorus) as well as other elements which are not specifically added.
  • the phosphorus content is preferably ⁇ 0.05 mass%, the sulfur content ⁇ 0.4 mass%, in particular ⁇ 0.04 mass%.
  • the content of all other melting-related steel accompanying elements is maximum per element. 0.3 mass%.
  • the costs can be reduced.
  • the steel Despite the decrease in the nickel content and the low molybdenum content or lack of molybdenum (ie without molybdenum additive), the steel has very good mechanical properties in a hydrogen atmosphere over the entire temperature range of -253 to at least + 100 ° C and pressure range from 0.1 to 100 MPa.
  • the steel in the solution-annealed condition (AT) at a test temperature of -50 ° C and a gas pressure of 40 MPa hydrogen in the tensile test at a strain rate of 5x10-5 1 / s, a Relative Reduction of Area (RAA) or relative Brucheinschnürung ( Fractional Z in air or helium / Fractional Z in hydrogen x 100%) of at least 90%.
  • R_Rm, relative yield strength R_Rp0.2 and relative elongation at break R_A5 are also at least 90%.
  • the high yield strength of the steel of 300 to 400 MPa is essential.
  • the steel can be solution annealed (AT). It can also be cold formed, in particular cold drawn or cold rolled used.
  • the steel has a very good weldability and good corrosion resistance.
  • the steel has a high resistance to hydrogen embrittlement in the entire temperature range from -253 ° C to at least + 100 ° C and pressure range from 0.1 to 100 MPa.
  • the steel thus represents a cost-effective hydrogen-resistant material for hydrogen technology.
  • the steel can be used in the hydrogen technology of automobiles for devices and components of systems for generating, storing, distributing and using hydrogen, especially when the devices come into contact with hydrogen.
  • a (high) pressure vessel for hydrogen storage, a (high) pressure vessel, a cryogenic (high) pressure vessel, or a liquid hydrogen tank from the steel can be used.
  • the steel has a stable austenitic structure.
  • the ⁇ -ferrite content of the steels is less than 5% by volume, preferably even no ⁇ -ferrite is present.
  • the yield strength Rp0.2 in the tensile test at a strain rate of 5x10-5 is 1 / s at -50 ° C in a hydrogen atmosphere of 40 MPa for Steel No. 1 200 to 300 MPa and for Steel No. 2 300 to 400 MPa.
  • the steel Due to the relatively low nickel content of up to 9% by mass and the absence of molybdenum, the steel is very cost-effective.
  • the steel with stable austenitic structure thus represents a cost-effective hydrogen-resistant material for hydrogen technology in motor vehicles.
