Product detail
Technical and purchasing information
Low carbon cast steel shot is a reusable metallic abrasive for blast-cleaning jobs where toughness, structural integrity, and predictable wear matter. Compared with conventional high-carbon cast steel shot, its lower carbon content and bainitic structure help it resist brittle cracking and wear more gradually through repeated cycles.
YUXIN supplies low carbon steel shot in sizes from S110 to S930. The range covers a spread of particle sizes that can be matched to different workpiece dimensions, surface conditions, blasting equipment, and cleaning requirements.

Why Bainitic Structure Matters
The microstructure of steel shot affects how particles behave under repeated impact. Low carbon cast steel shot has a bainitic structure rather than the martensitic structure common in high-carbon shot.
In service, bainite offers a useful combination of hardness and toughness. Instead of relying mainly on high hardness, low carbon shot is built to resist brittle fracture and wear more gradually during circulation. This can reduce the rapid generation of sharp fragments and fines when the abrasive is correctly matched to the blasting machine and workpiece.
Actual service life still depends on blasting velocity, wheel condition, workpiece hardness, separator efficiency, the operating mix, and how fatigue life is measured.

Main design emphasis
Toughness and gradual wear
Hardness, impact performance, and general-purpose cleaning
Particle breakdown tendency
Designed to reduce brittle cracking
More dependent on heat treatment, internal quality, and operating conditions
Typical use
Recyclable blast cleaning where toughness and stable wear matter
Broad shot-blasting and surface-cleaning applications
Both products are metallic abrasives, and neither should be selected on carbon content alone. Shot size, hardness, workpiece material, machine energy, surface condition, and required finish remain important selection factors.
Typical Applications
Low carbon steel shot suits general blast-cleaning work on ferrous parts, including:
Cleaning steel and iron castings
Removing scale from forgings and heat-treated components
Cleaning steel plate and structural steel
Cleaning fabricated steel components before further processing
Recyclable wheel-blast and air-blast systems
Surface preparation where repeatable impact and controlled abrasive wear matter
For coating preparation, match the shot size and blasting conditions to the required cleanliness and surface profile. If a strong cutting action or deeper angular profile is needed, steel grit may work better than spherical shot.
Size Selection
Larger shot carries more mass per particle and generally hits harder. Finer shot increases the number of impacts per unit area and gives denser coverage.
The current YUXIN low carbon steel shot range includes:
Confirm the actual particle-size distribution against the purchase specification and applicable size standard for the ordered grade.
Standards and Specification Framework
Low carbon cast steel shot is covered by dedicated international and industry specifications. ISO 11124-4:2018 sets requirements for low-carbon cast-steel shot used in blast cleaning, including hardness, density, structural/defect requirements, and chemical composition.
SAE J2175_202107 describes chemical analysis, hardness, microstructure, and physical characteristics for low carbon cast steel shot used in blast cleaning or shot peening.
For YUXIN supply, conformity to a particular standard, grade, or customer specification should be confirmed in the purchase specification and corresponding inspection documentation.
About Fatigue-Life Claims
Fatigue life matters for reusable steel shot, but results depend heavily on test method, shot size, test equipment, operating conditions, and failure criteria.
The supplied source material describes low carbon steel shot as having better fatigue resistance than high carbon steel shot. However, no test report or test method was supplied to support a fixed percentage improvement.
For that reason, this product page does not publish the separate claims of “about 70% higher fatigue life,” “below 3,000 cycles,” or any fixed cycle-life guarantee as a universal product performance value.
