Steel Grit

INTRODUCTION: Size: G120/G80/G50/G40/G25/G18/G16/G14/G12/G10 G120-0.2mm G80-0.3mm G50-0.4mm G40-0.7mm G25-1.0mm G18-1.2mm G16-1.4mm G14-1.7mm G12-2.0mm G10-2.5mm Secondary quenching steel shot and grit. The secondary hardening is hardening again, steel shot after a quenching centrifugal again hardening is called secondary hardening. Purpose: after the secondary hardening The microstructure of the steel shot or grit will be more dense, it significantly inhibited the deviation
