Specification

Spherical Cast Steel Shot

Spherical cast steel shot is a high-carbon cast abrasive with a hardness of 460–560 HV ± 40 HV (46–53 HRC) in accordance with ISO 11125-3.

It is designed for high-performance blast cleaning processes, particularly in automated shot blasting systems equipped with turbine wheels.

Chemical Composition

Chemical composition complies with ISO 11125-1 and SAE J827 standards.

Typical composition of cast steel:

Carbon (C): 0.8 – 1.2%
Manganese (Mn): 0.35 – 1.2%
Silicon (Si): minimum 0.4%
Sulfur (S) and Phosphorus (P): maximum 0.05%

Grain Size Range

Grain size distribution:
S 70 – S 1320, in accordance with SAE J444 (AUG 84, revised May 1993).

Main Applications

Spherical steel shot is primarily used in shot blasting machines with turbine throwing wheels for:

Cleaning castings from molding sand
Removing sprues from castings and metallurgical products
Removing mill scale from sheets, plates, and sections
Removing burrs from castings
Cleaning metallurgical products and components after machining or fabrication

Key Advantages

High durability and long service life
Consistent spherical shape for controlled impact
Uniform surface finish
High efficiency in automated blasting systems
