用途
本品选用锻造轴承钢冲切边脚料,经热处理后破碎,再经热处理筛选而成,此类钢砂为切割花岗岩石专用钢砂,具有:棱角度好、粒度均匀、耐磨性好等特点,经众多石材厂家多年使用证明,锯切石材速度更快、石材锯切板面更平整。
Application
Bearing Alloy Steel Grit is made of forged bearing steel off-cuttings by the process of heat treatment,crushingand size screening.It is specially used to cut granite and can help customers to achieve faster-cuttingefficiency and smoother cutting surface attributed to its sharp edges,uniform sizes and good wear resistance.
