Descaling & Scale Removal Services

Scale on your product or part is caused by natural and mechanical processes such as heat treating, welding, and oxidization. Arrow Cryogenics uses a variety of descaling methods to polish, finish or descale your parts, such as: abrasive blastingshot blasting, chemical descaling services, and vibratory finishing.

Descaling & Finishing Methods

We feature a wide variety of abrasive blasting and shot blasting machines to meet your descaling and finishing needs. Each of our machines utilizes a single type and size of media to avoid cross-contamination. Several of our machines are committed strictly to medical components, while our other machines can run descaling services for a wide variety of parts and products for the automotive, aerospace, & food industries.

Abrasive Blasting Surface Finish

Abrasive shot blasting is a surface finishing technique that involves rapidly impacting the surface of an object with a controlled stream of abrasive shot material. It is faster and more effective than filing or removing flash that may remain on a part after the casting or stamping process. Abrasive shot blasting is also used for removing burrs, scale and rust that may interfere with the part's integrity, appearance or definition. Shot blasting can also prepare the surface of a part for coating by removing surface contaminants and provide a surface profile for increased coating adhesion.

Vibratory Finishing for Heat Treated Scale Removal

Our vibratory descaling services are utilized extensively to remove heat treated scale from steel and stainless steel parts. Our vibratory finishing department has a wide variety of media available for advanced descaling capabilities. By using various sizes and compositions of media, we are able to achieve a wide range of finishes through our vibratory descaling services.

After your parts or components have gone through one of our vibratory descaling services, they may need to be protected from oxidization. Our customers may specify whether petroleum-based or non petroleum-based inhibitors may be used.

Chemical Descaling for Stainless Steel Industrial Parts

Our chemical descaling services are most often used on stainless steel because of its resistance to chemicals. Our chemical descaling services can remove the scale without attacking the stainless steel. After descaling, stainless steel parts may need to be passivated or electropolished. Chemical passivation and electropolishing improves the corrosion resistance of stainless steel.

Industrial Descaler Applications

Descaling is often used prior to the following applications:

  • Electropolishing
  • Painting
  • Plating

Descaling can also be used before or after a welding process, depending on your needs. Prior to welding, it is critical that weld joints and parts are free of mill scale and other contaminants. These foreign substances can potentially degrade the part’s metal properties and lower corrosion resistance.

You may also need to utilize our premium descaling services for cosmetic reasons or to ensure cleanliness for medical and electronic applications with stringent specifications. To meet our customers’ exacting requirements, Arrow Cryogenics also offers an on-site class 10,000 (ISO Class 7) clean room for the cleaning and packaging of parts.
