Steel Shot 550 - Blasting Media - 10 lbs.
S-550 Steel Shot (1.40 mm / 0.055" Dia.)
- MEDIUM-DUTY STEEL SHOT, STEPPED-UP POWER: S-550 delivers more aggressive cleaning power than finer sizes while still leaving a controlled, professional finish.
- FASTER DESCALING ON STRUCTURAL & AUTO PARTS: Strips heavier rust, mill scale, and coatings from auto frames, light structural steel, and machinery in fewer passes.
- STRONG SURFACE PROFILE FOR COATING ADHESION: Creates a deeper anchor pattern than smaller shot sizes, ideal for prepping surfaces ahead of industrial paint or epoxy.
- EFFECTIVE SHOT PEENING FOR MEDIUM COMPONENTS: Induces solid compressive stress in shafts, springs, and structural parts, improving fatigue resistance and durability.
- FOUNDRY & LIGHT CASTING CLEANUP: Removes residual sand and scale from small-to-medium castings and fabricated parts efficiently.
- DURABLE, LOW-ATTRITION CONSTRUCTION: Heat-treated high-carbon steel resists fracturing, so this shot keeps performing through extended recycling in blast systems.
FLEXIBLE EQUIPMENT COMPATIBILITY: Runs well in wheel blast machines, air blast systems, tumble blasters, and blast cabinets across a range of shop sizes.
- FAMILY-OWNED AND OPERATED: Winona Van Norman is a family-owned, family-run American manufacturer bringing generations of quality craftsmanship to every product we make in Wichita, Kansas.
