T12CrV锉刀钢系过共析钢,钢中加入少量Cr、V、B和稀土等合金元素,具有较高的淬透性,高的硬度和耐磨性。(稀土元素的加入,能将残余存在的夹杂物形状改变成球形状,能多方面改善钢质的作用,尤其可以提高钢的高温塑性)该钢种(T12·Cr·V)是由上海钢研所提出,由我厂试制生产半成品(元钢和扁坯),无锡钢锉厂制钢锉的一种新的钢种,它的目的是为赶超目前世界锉刀市场的王牌—美国产“双 T12CrV file steel hypereutectoid steel, steel by adding a small amount of Cr, V, B and rare earth alloy elements, has a high hardenability, high hardness and wear resistance. (The addition of rare earth elements can change the shape of residual inclusions into spherical shapes and can improve the effect of steel in many aspects, and in particular, the high temperature plasticity of the steel.) The steel (T12 · Cr · V) Research Institute proposed by the trial production of semi-finished products (yuan steel and slab), Wuxi Steel File Factory steel file a new type of steel, which aims to catch up with the trump card in the world market - the United States produced " double
