对工作表面没有伤害，使加工后的工件具有精细处理的效果。采用拉丝，裁切，磨圆等工艺精制而成．外观光亮，无锈，圆珠状（切丸，圆柱状）．广泛应用于铜，铝，锌，不锈钢等工件的表面喷抛处理，对于加工后的工件具有亚光效果，突出金属本色，不生锈等优点，无须进行酸洗除锈处理，而且耐磨是铸钢丸的３－５倍，可以降低生产成本．stainless steel ball:　　 adopting the drawing,cutting,grinding into roundness and other processes to make the surface is bright,no rust,round dew form(cutting ball,column form).it is extensively applied to the surface shot blasting treatment of workpieces,such as cu,al,zn and stainless steel ball etc.it can make the surface of work piece finishing after processed,extend metal substance and doesn ′ t rust,what ′ s more,it neddn ′ t acid washing and the wear-resistance of it is 3-5 times larger 　than that of casting steel ball.certainly ′ it can reduce product manufacturing cost.主要化学成份：　 sus 304奥氏体（autensite) 　c ≈ 0.08%（main chemistry) 　 mn ≈ 0.9%　cr ≈ 18%　　ni ≈ 9%　sus 430 马氏体（martensite)　c ≈ 0.10% 　mn ≈ 1.2%　　cr ≈ 17%　ni ≈ 1%比重(density):圆丸（round ball) 7.9g/cm3;切丸（cutting ball) 7.8g/cm3硬度（hardness):400-600hv规格（size):0.2mm-1.5mm 　　其它定制（else customized)
