Our steel shot is exceptionally durable ¡§c due to its low friability, the impact of blasting actually further tempers the shot so that its hardness increases over time, allowing the media to deliver consistent, repeatable performance over thousands of cycles. As produced, our steel shot has a hardness of 40-50hrc (390-510 h.V). And thanks to its extremely low breakdown rate, virtually no dust is produced. Delivering high-impact energy and fast cleaning rates, steel shot is used to for heavy scouring and to produce very bright finishes Steel shot size: s70, s110, s170, s230, s280, s330, s390, s460, s550, s660, s780, s930 Steel shot diameter: 0.2mm, 0.3mm, 0.5mm, 0.6mm, 0.8mm, 1.0mm, 1.2mm, 1.4mm, 1.7mm, 2.0mm, 2.5mm, 3.0mm Steel shot used for shot blasting , shot peening
