Latest Patents
Yamauchi's latest patents focus on a fracture-resistant stainless steel sheet and the method for producing it. One of his notable inventions describes a stainless steel sheet that includes non-metallic inclusions of Al.sub.2 O.sub.3, MnO, and SiO.sub.2. These inclusions are strategically composed to enhance the material's strength, achieving an 1.0% on-set stress of at least 1520 N/mm.sup.2 (155 kgf/mm.sup.2). Additionally, the sheet demonstrates an anisotropic difference of 1.0% on-set stress of 196 N/mm.sup.2 (20 kgf/mm.sup.2) or less, along with an Erichsen number of at least 4.6 mm. The method for producing this high fracture-resistant stainless steel sheet involves a series of processes including annealing, pickling, and multiple stages of cold rolling and heat treatment.
