Definitions
- the invention relates to a corrosion-resistant steel with high resistance to hydrogen-induced embrittlement in the entire temperature range (-253 to at least + 100 ° C), in particular between -100 ° C and room temperature
- the proposed steel is suitable for all hydrogen-contacting metallic components such as hydrogen tanks, liners, bosses, valves, pipes, springs, heat exchangers, fittings or bellows.
- Nickel is, however, like molybdenum, a very expensive alloying element, so especially for a
- Mass production e.g. Tank components in the automotive sector lack cost-effective hydrogen-resistant steels.
- Corrosion resistant and can be well hot and cold forming and welding.
- composition reached:
- the steel according to the invention can therefore be produced with or without boron.
- the lower limit of the content of silicon is in the
- the alloy according to the invention may have an yttrium content of 0.01 to 0.2, in particular to 0.10 mass%, wherein yttrium wholly or partly by 0.01 to 0.2, in particular to 0.10 mass% of a of elements: scandium, lanthanum or cerium may be substituted.
- the hafnium and zirconium content is respectively
- hafnium or zirconium may be wholly or partially replaced by 0.01 to 0.2, in particular to 0.10 mass% by titanium.
- the melting-related steel accompanying elements comprise common production-related elements ⁇ e.g. Sulfur and
- the phosphorus content is preferably ⁇ 0.05% by mass, the sulfur content ⁇ 0.4% by mass, in particular ⁇ 0.04% by mass.
- the content of all steel accompanying elements due to melting is at most 0.3 mass% per element.
- the alloying costs of the steel according to the invention can be drastically reduced.
- the steel according to the invention has very good mechanical properties in one
- the steel according to the invention can be solution-treated (AT). It can also be cold formed, in particular cold drawn or
- the steel according to the invention may be a stable austenitic steel having an austenite content of at least 90 mass%.
- the steel may also be formed as austenitic-ferritic steel (duplex steel).
- the ⁇ -ferrite content can be 10-90, in particular 10-60, volume Percent. Remarkably, even with a high ⁇ -ferrite content, a very high hydrogen resistance is present.
- the steel A of the invention has the following composition ⁇ in% by mass):
- the remainder of the iron and steel elements accompanying the fusion have an austenitic-ferritic structure (duplex steel).
- the ⁇ -ferrite content of the steel is 15-35% by volume.
- the yield strength Rp0.2 at -50 ° C in a hydrogen atmosphere of 40 MPa is more than 500 MPa.
- the relative fracture constriction (

- the steel according to the invention 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 austenitic-ferritic microstructure according to the invention thus provides a cost-effective, hydrogen-resistant structure Material with high strength for the hydrogen technology and is therefore very well suited for springs in particular.
- the steel can be used for devices and components of systems for the generation, storage, distribution and use of hydrogen, especially when the
- Pressure sensors, etc. including parts of these devices, such as e.g. Feathers and bellows.
- the steel B according to the invention with the following composition (in% by mass):
- the remainder of the iron and steel elements accompanying the fusion have a stable austenitic structure.
- the ⁇ -ferrite content of the steel is less than 10 percent by volume.
- the yield strength Rp0.2 at -50 ° C in a hydrogen atmosphere of 40 MPa is 250 to 300 MPa.
- the relative fracture constriction ⁇ fracture contraction Z in helium / fracture constriction Z in
- Hydrogen x 100% is between 85 and 100%. When cold forming this steel occurs only a very small
- This steel is therefore characterized by a very high austenite stability.
- the steel can be used in particular for devices and components of systems for the generation, storage, distribution and use of hydrogen, in particular if the
- Pressure sensors, etc. including parts of these devices, such as e.g. Feathers and bellows.
- the invention relates in particular to steels for hydrogen technology in motor vehicles. It can for
- Hydrogen storage a (high) pressure vessel, a cryogenic (high) pressure vessel, or a liquid hydrogen tank can be used from the steel according to the invention.
- the steel is also suitable for non-automotive applications in solution-annealed applications Condition must have a high yield strength (steel A) or excellent cold workability or austenite, especially after cold forming need (steel B).
- compositions of steels prepared according to the invention reproduced.
- the amounts of each element in the steel are expressed as mass% fractions.
- the actual values are given for steels Nos. 1 to 7 and the nominal values for steels Nos. 8 to 10.
- the steels have a low relative stress at a test temperature of -50 ° C. and a gas pressure of 40 MPa hydrogen in the tensile test at a strain rate of 5 ⁇ 10 -5 1 / s
