Latest Patents

Sakamoto holds a patent for an austenitic heat-resistant steel that forms an oxide film primarily composed of Al.sub.2 O.sub.3 in high-temperature oxidizing atmospheres. This steel consists of not more than 0.2% carbon, not more than 1.0% silicon, not more than 2.0% manganese, 12 to 37% nickel, 9 to 25% chromium, and more than 4.5 but not more than 6% aluminum. Additionally, it includes at least one member selected from the group consisting of titanium, niobium, and zirconium in a total amount of not more than 0.8%, with the balance being iron. The steel's delta-ferrite value is calculated to be from 0 to 7.9, and it is designed to remove an internal oxide layer formed during hot working.
