日本ＮＫＫ公司已开发出新型无取向高碳冷轧薄带钢。该钢种是生产汽车用传动部件,如齿轮的理想产品。尽管通常条件下,汽车用传动部件通过铸造或铸造工艺加以生产,但为降低生产成本,采用了冲压成形工艺。然而,冲压成形工艺生产中也存在几个缺陷,因该工艺所使用的薄带钢具有各向 Japan NKK company has developed a new non-oriented high-carbon cold-rolled strip. This steel is the ideal product for the production of transmission components for automobiles, such as gears. Although the transmission components for automobiles are usually produced through a casting or casting process under normal conditions, a press-forming process is adopted to reduce the production cost. However, there are several drawbacks in the stamping process because thin strips of steel used in this process have various orientations
