摘要： The present invention provides a razor blade steel and method of forming a razor blade from a steel which has a high hardness but is also ductile after being subjected to a heat treatment and bending process. The novel razor blade steel has Molybdenum (Mo) content of between about 1.6% to about 5% in weight percent of composition. The razor blade comprises substantially no tempered carbide, tempered carbide of about 0.1 μm or smaller, and substantially no cracks in a bent portion. One embodiment of the novel razor blade steel has a composition comprising, in weight percent, about 0.45% to about 0.55% of C, about 0.4% to about 1.0% of Si, about 0.5% to about 1.0% of Mn, and about 12% to about 14% of Cr, and further includes Mo in an amount of about 2.1% to about 2.8%.
