軸承鋼砂是用軸承鋼沖切下的邊角薄片，經(jīng)淬火、破碎而成。此種尖角砂無縮孔、無疏松、品粒度細(xì)、硬度*，棱角鋒利，是目前鋸切花崗石的磨粒磨料。根據(jù)客戶需求，不同的用途分為三組。
A組：硬度>60HRC
用途：鋸切花崗石
特征：品粒度細(xì)，硬度*，棱角鋒利，耐靡性能好。

B組：硬度53-60HRC
用途：金屬表面強(qiáng)化處理或除氧化皮工作。
特征：硬度高、韌性好、耐磨性能好

C組：硬度40-50HRC
用途：金屬表面除銹或除氧化皮工作。
特征：耐磨性能好、噴砂效率高。

The bearing is bearing steel grit cutting under the edges of the sheet, after quenching, broken into. This kind of sharp sand has no shrinkage hole, no loose, fine grain size, high hardness, sharp edges and corners, it is the most ideal abrasive grain. According to customer needs, different purposes are divided into three groups.
Group A: hardness >60HRC
Usage: Sawing Granite
Features: fine grain size, high hardness, sharp edges and corners, good resistance to wear.
Group B: hardness 53-60HRC
Use: metal surface treatment or descaling work.
Features: high hardness, good toughness, good wear resistance
Group C: hardness 40-50HRC
Use: metal surface rust or descaling work.
Features: good wear resistance, high sandblasting efficiency.http://m.kytsldc.cn/st6871/list_447942.html
