1. Execution standards for steel shot production:
We strictly comply with the national standard "GB/T18838.3-2008 High Carbon Cast Steel Shot and Sand", "SFSA20-66 Cast Steel Abrasive Standard" of the American Steel Association, "SAE J827 Cast Steel Shot Standard" of the American Society of Automotive Engineers, the People's Republic of China Ferrous metallurgy industry "YB/T5149-93 cast steel shot", US military standard "MIL-S-851 standard for cleaning and strengthening metal steel grit and steel shot" and the International Organization for Standardization "ISO11124-3 standard high carbon cast steel shot" Cast steel sand standard" to produce.
2 .Main technical indicators of steel shot:
Name (steel shot) Chemical composition of cast steel shot Carbon (C) 0.70~1.20% Manganese (Mn) 0.35~1.20% Silicon (Si) ≧ 0.4 Sulfur (S) ≤ 0.05% Phosphorus (P) ≤ 0.05% Average hardness
Regular: 40~50HRC (377~509HV)
Special: 52~56HRC (543~620HV)
Special: 56~60HRC (620~713HV) hardness deviation, the maximum deviation range is ±3.0HRC, tempered martensite or tempered troostite density with uniform metallographic structure
Bulk density 7.4g/cm3
