前言 T12CrV是我国根据各国钢锉生产的特点、自行设计的新钢种,是目前能取代生产钢锉普遍采用的T12、T12A、T13、T13A等碳素工具钢,为赶超美国“双刀”牌钢锉的最新锉刀专用钢,现已通过冶金部和轻工部的鉴定。其特点是:钢中含有少量的Cr、V、RE、B等合金元素,使钢锉具有较高的硬度及耐磨性。因此,使用寿命也显著提高。由于T12CrV为新钢种,在锉刀生产工艺方面还有待于进一步完善,特别在热处理方面,还可以进一步挖掘潜力,以优质、高
Foreword T12CrV is our country according to the characteristics of steel file production, design of new steel, is currently able to replace the production of steel file commonly used T12, T12A, T13, T13A and other carbon tool steel, to catch up with the United States “double knife” The latest file for the steel file special steel, metallurgy and the Ministry of Light Industry has now been identified. Its characteristics are: steel contains a small amount of Cr, V, RE, B and other alloying elements, the steel file with high hardness and wear resistance. As a result, service life is also significantly increased. As T12CrV for the new steel, in the file production process has yet to be further improved, especially in the heat treatment, but also can further tap the potential to high quality, high
