Austenitic steel, useful in a partial direct contact region to a hydrogen containing fluid, preferably for a hydrogen tank, comprises alloy of e.g. chromium, manganese, nickel, silicon, carbon, nitrogen, aluminum and residue of iron

摘要

Austenitic steel comprises alloy (in mass%) of chromium (10.0-23), manganese (3-9), nickel (3-8), silicon (0.2-3), carbon (0.05-0.15), nitrogen (0.001-0.03), aluminum (0.005-0.15), residue of iron and smelting impurities, where the alloy is free from molybdenum, where the steel has embrittlement resistant properties compared with the hydrogen.
