Winona Van Norman S-280 Steel Shot Blasting Media (280 Grit)

Winona Van Norman S-280 Steel Shot Blasting Media (280 Grit) is a premium, highly reusable spherical shot blasting abrasive engineered to deliver maximum kinetic energy for rapid industrial descaling, structural steel preparation, and high-volume wheel blast cleaning. Featuring a perfectly balanced 0.71 mm (0.028") size, this heavy-duty steel shot abrasive effectively strips mill scale, rust, and old coatings from forged iron workpieces, and serves as the trusted automotive machine shop standard for aggressively cleaning cast iron engine blocks without altering critical tolerances. By striking metal surfaces with high-impact force, it creates a consistent, "dimpled" surface profile for optimal industrial coating adhesion, while its ultra-durable round shape maximizes recycled blasting cycles and minimizes blast equipment wear compared to slag or glass bead alternatives.

Key Performance Benefits & Features:

• Versatile Industrial Descaling: The industry "go-to" size for rapidly removing heavy mill scale, rust, oxidation, and old industrial coatings from medium-sized forged steel and iron parts.

• Consistent Surface Profile: Produces a reliable, uniform "dimpled" anchor pattern across metal surfaces, ensuring optimal adhesion for heavy-duty protective coatings and paints.

• Automotive Engine Rebuilding standard: Highly effective for deep-cleaning cast iron engine blocks, cylinder heads, and automotive components without warping or altering dimensional tolerances.

• Extreme Reusability & Cost Efficiency: Engineered for maximum durability to withstand multiple repeated impact cycles. Lasts significantly longer than slag, garnet, or glass bead abrasives, drastically lowering your overall cost-per-use.

• Reduced Blast Equipment Wear: The premium spherical shape eliminates sharp edges, minimizing friction and extending the lifespan of your blast machine liners, blast wheels, and blades.

• Structural Steel Preparation: The ideal abrasive media for prepping metal plates, steel sections, and structural frames prior to welding or industrial coating applications.
