1.硼铁的用途与品种硼一般以微量加入钢中,其含量随钢种而稍有不同,钢中含有0.007%的硼可显著提高其可淬性,普通低合金钢含硼为0.0005—0.007%。在调质钢中硼可以代替很多其它合金元素而不会影响钢的机械性能。为了改善不锈钢的加工性能,最好在铁素体中加入少量硼(约0.003%)。硼在铸铁中属于中含量的范围,它能影响石墨化,故能增加白口的深度。硼添加量 1. The use and variety of boron iron Boron is generally added to the steel with a trace amount of its content slightly different with the steel, steel containing 0.007% of boron can significantly improve its hardenability, ordinary low-alloy steel boron is 0.0005- 0.007%. Boron in quenched and tempered steel can replace many other alloying elements without affecting the mechanical properties of the steel. In order to improve the workability of stainless steel, it is best to add a small amount of boron in ferrite (about 0.003%). Boron in cast iron belongs to the range of content, it can affect the graphitization, it can increase the depth of the white mouth. Boron dosage
