🔧 Technical Specifications of Cast Steel Shot

1. Chemical Composition

• Carbon (C): 0.70 – 1.20%

• Manganese (Mn): 0.35 – 1.20%

• Silicon (Si): 0.40 – 1.20%

• Sulphur (S): ≤ 0.05%

• Phosphorus (P): ≤ 0.05%

This balanced composition ensures hardness, toughness, and wear resistance.

2. Mechanical Properties

• Average Hardness (500 g load):

  • General grade: 40 – 50 HRC (377 – 509 HV)

  • Special grade: 52 – 56 HRC (543 – 620 HV)

  • Extra high grade: 56 – 60 HRC (620 – 713 HV)

• Hardness Deviation: ± 3.0 HRC or ± 40 HV

• Metallurgical Structure: Uniform tempered martensite or troostite with diffusely distributed carbides

3. Physical Properties

• Minimum Density: ≥ 7.4 g/cm³ (measured by alcohol displacement)

• Shape: Spherical particles with smooth surfaces

• Size Range: SAE standards (e.g., S110, S330, S550, etc.)

⚙️ Applications of Cast Steel Shot

1. Surface Preparation

• Shot blasting: Removal of rust, scale, and old coatings

• Pre-welding treatment: Roughening surfaces for better adhesion

• Pre-coating treatment: Preparing surfaces for painting, galvanizing, or other coatings

2. Shot Peening (Surface Strengthening)

• Automotive industry: Springs, gears, crankshafts — improving fatigue resistance

• Aerospace industry: Aircraft components — preventing microcracks and extending service life

• Heavy machinery: Increasing durability of load-bearing parts

3. Industrial Cleaning

• Foundries: Cleaning castings and removing sand residues

• Shipbuilding: Hull and tank rust removal

• Pipelines and tanks: Internal surface cleaning against corrosion

4. Advantages

• High impact resistance → long service life

• Reusable multiple times → cost-effective

• Low dust generation → cleaner working environment

• Different hardness grades → adaptable to various applications

📌 Important Note: Cast steel shot does not have a CAS number, since it is an alloyed metal product, not a single chemical compound. Identification is made through standards like SAE J827, ISO 11124-2, DIN specifications.
