Blast Cleaning

Cincinnati Steel Treating offers a wide variety of blast cleaning services for multiple types of parts including shot blasting for large parts, tumble blasting for small parts, and glass bead blasting for specialty finishes. CST can perform blast-only services on a commercial basis, or we can offer blast cleaning as a finishing touch on parts that we have heat-treated. Ask one of our process engineers for the best blast process to use to provide the ideal surface finish for a part.

Cincinnati Steel Treating Blast Capabilities

Cincinnati Steel Treating (CST) has a large shot blast table that measures 96” in diameter and can hold parts up to 36” in height. The table is capable of holding 5,000 pounds. A tumble blast unit is also available that can blast clean parts one at a time that are up to 36” tall and 18” in width. The tumble blast can handle four parts at once with a weight limitation of 50 pounds per part, or 200 pounds per

load. The glass bead blast cabinet can handle dimensions of 36” in width by 12” in height with a weight limit of 20 pounds per part. The glass bead blast provides a fine, clean surface free of the pitting that occurs with shot or tumble blasting.

Applications of Shot Blasting

Shot Blasting has been performed by Cincinnati Steel Treating on parts that are destined for the food processing industry, military applications where the type of blast medium and the degree of surface finish are specified, and for large forgings that are machined after heat treat into gears, shafts, or other power transmission components. CST has experience in blast cleaning a wide variety of materials. We

have shot-blasted everything from aluminum to medium carbon alloy steel to stainless steel and Inconel. CST has even developed a method for shot blasting retorts from heat treating furnaces in order to bring them back into serviceable condition. CST’s shot blasting process produces a pristine surface that can lower a customer’s costs by reducing subsequent machining operations as well as producing a cosmetically appealing surface on the part before it is installed into its final application. Ask one of CST’s engineers for recommendations of which blast cleaning process to use when deciding upon the best method to process a particular part.

Shot Blasting/Blast Cleaning– How it works

Shot blasting is a process where hardened shot is propelled at high velocity against the surface of a heat-treated part. The shot can be composed of many different types of material, but we choose to use only steel shot to avoid damaging semi-finished parts. An even more delicate form of blast cleaning comes in the form of glass beads that deflect off the surface before deforming it. All of these various

types high velocity grit particles collide with the oxides/dirt/oil residue on the surfaces of the parts when they are applied, knocking them off as the blast goes through its cycle. Such a process will remove all dirt, including paint off of a surface. The part emerges from the blast cabinet with a clean surface that is free of contaminants. Steel shot will leave a mottled surface on the parts, which can be undesirable, so glass bead blasting can be used when it is wished to avoid such a surface.
