Latest Patents
Miyakawa holds a patent for a low alloy steel that exhibits excellent stress corrosion cracking resistance. The patent details a specific composition of nickel-chrome-molybdenum steel, which includes the following elements: carbon (C) at a maximum of 0.40%, silicon (Si) at a maximum of 0.15%, manganese (Mn) at a maximum of 0.20%, phosphorus (P) at a maximum of 0.010%, sulfur (S) at a maximum of 0.030%, nickel (Ni) ranging from 0.50% to 4.00%, chromium (Cr) ranging from 0.50% to 2.50%, molybdenum (Mo) ranging from 0.25% to 4.00%, and vanadium (V) at a maximum of 0.30%. The composition is designed to ensure that the sum of Si, Mn, and 20P does not exceed 0.30%, with the remainder consisting of iron and unavoidable impurities. The prior austenite crystal grain size is specified to be in excess of 4 of ASTM crystal grain size number. This innovation is crucial for industries that require materials with high resistance to stress corrosion cracking.
