General chemical composition:
Carbon | 0.80 – 1.20 % |
Silicon | 0.40 – 1.50 % |
Mangan | S070 – S110 0.35 – 1.20% |
S170 0.50 – 1.20% | |
S230 – S660 0.60 – 1.20% |
Physical properties:
Microstructure | Uniform martensite tempered to a degree consistent with the hardness range. |
Hardness | 41 – 51 HRC. Other hardnesses available upon request. |
Density | The specific density of cast steel shot shall not be less than 7 gm/cc. |
Steel Shot is widely to clean metal surface, especially by shot blasting machine (wheel). Steel Shot provides a greater penetration effect because of the smaller point of contact.
