SEPPE Low Carbon Steel Shot is produced through controlled deoxidation steelmaking with lower carbon content and stable internal structure. It is designed for long service life, low dust generation, gentle impact and fatigue-critical shot peening applications where toughness and stable consumption are important.
| Product | Low carbon cast steel shot |
| Main Sizes | S170, S230, S280, S330, S390, S460 |
| Other Names | Low carbon steel shot, long-life shot peening steel shot |
| Main Use | Shot peening, thin plate cleaning, precision casting cleaning and low-dust blasting |
| Manufacturer of Material | SEPPE TECHNOLOGIES |
• A long-life steel shot for customers who want very low breakage, lower dust and gentler impact on workpieces.
• Low carbon structure supports gradual abrasion instead of sudden cracking.
• Suitable for fatigue-critical shot peening and precision parts where surface damage must be controlled.
• Long service life: Service life can reach approx. 3300-3800 cycles under suitable working conditions.
• Low breakage: Consumed mainly by gradual abrasion instead of cracking, helping reduce dust.
• Gentle impact: Helps avoid dents on thin sheets, aluminum parts and precision components.
• Machine protection: Lower breakage helps reduce wear on blast wheels and spare parts.

 | Shot Peening Strengthening ▸ Used for gears, springs, crankshafts, bearings and leaf springs requiring fatigue improvement. ▸ Low carbon structure supports gentle impact and stable peening intensity. ▸ Suitable for fatigue-critical parts where low breakage and process repeatability are important. |
 | Thin Plate Cleaning ▸ Used for cold-rolled steel plates, galvanized sheets, aluminum stamping parts and container plates. ▸ Gentler impact helps reduce dents and surface damage on thinner workpieces. ▸ Suitable for low-dust blasting where workpiece protection is more important than maximum cutting force. |
 | Precision Casting Cleaning ▸ Used for sand removal and deburring on aluminum castings and precision cast parts. ▸ Gradual abrasion and low breakage help protect fine casting details during cleaning. ▸ Suitable for customers who require lower dust, cleaner equipment and stable surface quality. |
 | High-end Hardware & Aerospace ▸ Used for high-end hardware, machined parts and aerospace-related components. ▸ Controlled impact helps support clean finishing with less abrasive breakage. ▸ Suitable for applications where low dust, stable quality and workpiece protection are required. |
• Choose low carbon steel shot when low dust, low breakage and long life are the main purchasing points.
• Use fine sizes for thin sheets and precision parts.
• Use medium sizes for shot peening and general cleaning where workpiece protection matters.
• Selected steel raw material - induction furnace melting - atomization - drying - screening - heat treatment - final screening - packaging.

• Common packaging includes 25 kg bags, 1000 kg jumbo bags, palletized bags and customized export packaging. Bag marks and pallet protection can be arranged according to purchase requirements.
• Palletized small bags are available for easier forklift handling, warehouse stacking and container loading.
• Loading photos, batch labels and inspection records are available to support shipment traceability.
• It is selected for long life, low dust, low breakage and gentle impact on sensitive workpieces.
• It is better for long-life and low-dust applications, while high carbon grades may be preferred when stronger immediate cleaning force is needed.
• Yes. Low carbon steel shot is often used for fatigue-critical peening applications.
• Thin plates, aluminum parts, precision castings and automotive parts are common application areas.
• It tends to wear by gradual abrasion instead of sudden cracking, helping reduce dust and abrasive loss.
• Lower breakage and lower dust can help reduce wear on blast wheels and spare parts.
