钢砂 (铬钼合金钢砂、铸钢砂):采用精选的原材料，添加最佳配比的合金，经电炉熔炼，再转化为钢粒。在液体金属形成钢粒的过程中，其化学成份、粒度都受到严格控制，确保其机械特性符合各种用途之钢丸。钢粒经高温热处理后，再破碎成钢砂，最后由自动化的筛选系统筛出各种规格之砂粒。 [GP棱角钢砂] GP PYRAMIDAL STEEL GRIT 此种磨料新制成时，是尖棱状的，使用过程中棱角很快就被磨圆，特别适合于钢材表面去氧化皮预处理作业。 Angular when new,this grit rapidly rounds off in use and is particularly suites for decaling applications. [GL棱角钢砂] GL PYRAMIDAL STEEL GRIT 尽管此类钢砂的硬度比GP钢砂要高一些，但在喷砂过程中仍会失去棱角，特别适合于钢材表面驱除氧化皮预处理作业。 Although harder than GP steel grit,GL also loses its sharp edges during shotblasting and is particularly suited to descaling and surface preparation applications.

[GH棱角钢砂] GH PYRAMIDAL STEEL GRIT 　　此类钢砂硬度很高，在喷砂作业中会始终保持棱角，对形成规则的，毛发的表面特别有效。GH钢砂用于喷丸机作业时，应考虑施工要求优先于价格因素的场合（如冷轧厂的轧辊处理）。此钢砂主要用于压缩空气喷丸设备。　　 　Having maximum hardness,GH always remains angular in its operating mix. These abrasives are particularly effective in surface treatment processes and produce a uniform,etched inish.GH angular grit should only be used in wheel machines where working requirments take precedence over cost price considerations(for example with rolling mill cylinders or when a special finish is needed).For use mainly with compressed air equipment.
