Ship Cleaning Grit Angular Steel Grit for Ship Hull Surface Treatment

Ship Cleaning Grit Angular Steel Grit for Ship Hull Surface Treatment

Bearing steel grit is made with bearing steel materials, a high – strength steel materials, so this type steel grit is with good hardness and longer fatigue life than cast steel grit.
1)Hardness >60HRC
Used for granite cutting, surface treatment for cold roll and pre-treatment of metal parts.
2)Hardness >53- 60HRC
Used for removing corrosion surface, preparation for coating.
3)Hardness >40-50HRC
Used for metal surface cleaning, such as casting parts.
