Steel Grit
Steel Grit is made by crushing steel shot to angular particles subsequently tempered to different hardness to cater for different application, screened by size according to SAE Standard specification.
Specification
|
|||||||||||||||
| Standard Hardness The steel grit is manufactured by crushing the fully hardened shot to granular grit form, screening and tempered to three different hardness range as follows : GH = 63-67 HRc. GL = 56-60 HRc. GP = 40-50 HRc. It is also available in tempering to various hardness range for special application |
| Microstructure The microstructure of steel grit shall be uniform martensite, tempered to a degree consistent with the hardness range,with fine,well distributed carbides, if any. |
| Density The density of steel grit shall be not less than 7.4 g/cc. |
