2、硬 度Hardness

3、五大元素技术指标

碳(C)  0.85-1.20

锰(Mn)  0.60-1.20

硅(Si)  0.40-1.20

硫(S)  ≤0.05

磷(P)  ≤0.05

硬度与清理速度成正比，但与寿命成反比。所以硬度高、清理速度快，但寿命短消耗量大，故硬度应适中(约HRC40-50为宜)以产生最经济

之效果。

适中的硬度，具有优良的反弹性，则于喷抛中每一隅角皆能充分清理，

减少处理时间。

抛射材内部缺陷如气孔龟裂，内缩孔等皆可影响其寿命而增加消耗量。

密度大于7.4g/cm3则内部缺陷当越于最小

   Strength is in direct proportion to cleaning speed while it is ininverse proportion to durability,so the products with high strength andquick cleaning speed have a short durability.The optimum choice isproduct with moderate strength(about HRC40-50).

   Products with moderate strength and excellent elasticity canthoroughly clean up every parts of the processing units and reduce theprocessing time, Iteror flaws such as air bells will afet the durbiliythus resulting in greater consumption.

  When the density is more than 7.4/cm3,the products have the leastinterion flaws.

4、严密的品质管理，材质均匀

    SS钢丸、SS钢砂每- -个生产过程皆经过严密的品质管理，材质均匀，可使表面处理工作之进行标准化。

    Strict quality control and first rate products.

   Strict quality control goes with every process of           manufact-ure of SS steel

   shots and SG steel grits. Our products can                     modernize your surface processing  work.
