Steel abrasives are steel particles that are used as abrasive or peening media. [1] They are usually available in two different shapes (shot and grit) that address different industrial applications. Steel shot refers to spherical grains made of molten steel through an atomization ("granulation") process, available in different sizes and hardnesses.
Media choices include spherical cast steel shot, ceramic bead, glass bead or conditioned (rounded) cut wire. [7] Cut wire shot is preferred because it maintains its roundness as it is degraded, unlike cast shot which tends to break up into sharp pieces that can damage the workpiece. Cut wire shot can last five times longer than cast shot.
In metallurgy, peening is the process of working a metal's surface to improve its material properties, usually by mechanical means, such as hammer blows, by blasting with shot (shot peening), focusing light (laser peening), or in recent years, with water column impacts (water jet peening) and cavitation jets (cavitation peening).

Smooth cast surfaces (Ra 1–2.5 micrometres or 0.04–0.10 thou rms). Thinner walls can be cast as compared to sand and permanent mould casting (approximately 0.75 mm or 0.030 in). Inserts can be cast-in (such as threaded inserts, heating elements, and high strength bearing surfaces). Reduces or eliminates secondary machining operations.
Cast parts often require machining to achieve accurate tolerances and desired surface finishes. Carbon steel is the easiest type of steel to machine. High-carbon steel can be more time consuming to cut or grind, and will wear tools faster. Low-carbon steel can get gummy, making it difficult to work with.
Round shot was made in early times from dressed stone, referred to as gunstone (Middle English: gunneston), but by the 17th century, from iron. It was used as the most accurate projectile that could be fired by a smoothbore cannon, used to batter the wooden hulls of opposing ships, fortifications, or fixed emplacements, and as a long-range anti ...

Thick slabs are available up to 2200×450 mm at a specific steel facility, generically ranging typically from 200mm to 300mm; Thin slabs (low-carbon steel): 1680×50 mm at a specific facility, generically ranging from 40mm to 110mm thick depending on an individual machine's design [1] [3] Conventional bloom casters cast sections above 200×200 mm.
