The alloy steel Gr B5 washers are crafted from a special blend of chromium-molybdenum-vanadium steel, which contains about 5% chromium. This composition significantly boosts their resistance to oxidation and corrosion, especially in harsh environments. They go through rigorous heat treatment processes like quenching and tempering to achieve impressive tensile and yield strength while ensuring excellent creep resistance. These mechanical properties make them perfect for critical assemblies that face sustained high stress and temperature changes.
