Features: Medium to large spherical steel shots, high cleaning efficiency, balancing sand and rust removal with shot blasting reinforcement; Suitable for heavy oxide scale, large castings, thick steel plates, and heavy steel structures; Not suitable for precision small parts or thin-walled parts (prone to deformation).
Corresponding to the K-ABRASIVES PRODUCT LINE, THE X-ABRASIVES double-quenching version has a longer lifespan and is suitable for continuous high-strength shot blasting conditions.
1. Foundry Industry (Core Applications)
1). Sand cleaning for medium and large cast iron and casting steel parts
Excavator and loader bodies, machine tool beds, engine cylinders, and transmission housings; shot blasting removes molding sand, core sand, flash burrs, and removes sand adhered to casting surfaces, with fast cleaning speed, suitable for mass production of hook-type and crawler-type shot blasting machines.
2). Scale removal from forgings and heat-treated parts
Large forgings, shafts, and gear blanks; Remove the thick black oxide layer from forging, quenching, and tempering, ensuring a uniform surface while applying light surface strengthening.
2. Pre-treatment of steel structures and steel plates
1). H-beams, I-beams, steel plates, storage tanks, bridge components
Steel plate pretreatment lines, steel section shot blasting lines; Removes oxide scale, rust, and old coatings to achieve Sa2.5-Sa3 grade surface layers for painting and anti-corrosion priming; Mostly used for factory steel structures, bridges, pressure vessels, storage tanks, and container frames.
2). Shot blasting and rust removal of steel pipes and thick-walled fittings
Large-diameter steel pipes, petroleum pipelines, and steel structure fittings are used to remove rust layers and oxide scale from both internal and external surfaces.
3. Construction machinery & mining equipment
- Excavators, cranes, mine crushers, mining truck frames, wear-resistant castings;
- Removes welding spatter, welding slag, and oxide scale, while improving the fatigue strength of part surfaces; suitable for heavy-duty track shot blasting and hook shot blasting equipment.
4. Shipbuilding and Marine Engineering
- Hull sections, decks, bulkheads, anchor chains, rudder shafts, shipboard forged castings;
- Shot blasting removes rust, old paint, and marine deposits, providing pretreatment for anti-corrosion coating on ships. At the same time, shot blasting is applied to load-bearing parts such as anchor chains to enhance fatigue resistance.
5. Wind power and energy equipment
- Wind turbine towers, flanges, hubs, spindles, gearbox housings;
- Removal of forged and cast scale and shot blasting strengthening, enhancing fatigue resistance, suitable for harsh outdoor working conditions; surface pretreatment for boiler pressure vessels and pressure pipelines.
6. Rail transit
- Locomotive frames, bogies, wheels, large steel structural components;
- Rust removal and scale removal, shot blasting reinforcement, improving component fatigue life, meeting rail transit component standards.
7. Model Selection Comparison
Model Size Typical Uses
S550 1.7 mm for medium and large castings, thick steel plates, heavy steel structures, and forgings, with sand removal and rust removal strengthening
S460 1.4 mm small to medium-sized castings, medium-thickness steel plates, general working conditions
S660 2.0 mm extra-large heavy castings and thick plates, heavy working conditions, greater impact force
Tip: For thin-walled parts and precision small parts, prioritize S330/S390 to avoid deformation of the work-piece.
Summary:
Steel Shot S550 (1.7mm) comply with SAE J444 standard
S550 is widely used for heavy-duty shot blasting. Main applications sand removal for medium-large cast iron & steel castings, descaling of forgings & heat-treated parts, surface preparation for steel plate, H-beam, ship hull, wind turbine tower, heavy-duty construction machinery and bridge steel structures. It delivers high cleaning efficiency and a moderate shot‑peening effect.
Our K-ABRASIVES is standard grade, X-ABRASIVES double-quenched version provides longer fatigue life for continuous heavy-load production.
