In the previous article, we have systematically answered the definition, application, and model of steel shot, we know that steel shot is an excellent industrial abrasive and has a huge application market. Today we gonna discuss another industrial abrasive-stainless steel shot.

Explanation of Stainless Steel Shot

Definition of Stainless Steel Shot

Stainless steel shot is a regular particle cut from premium stainless steel wire. It is often referred to as a stainless steel wire cut shot.

It is mostly used for a copper alloy, aluminum alloy die castings, and stainless steel parts for surface shot blasting, sandblasting, shot peening treatment, shot peening forming, finishing, matte, correction, paint removal, and corrosion removal.

It is refined by processes such as drawing, cutting, and rounding, and has a bright and rust-free appearance. It is in the shape of a round bead (cut shot, cylindrical), and has better wear resistance than ordinary cast steel shot on the market.

Manufacturing Process of Stainless Steel Shot

Stainless steel shot is made using a rigorous process that yields spherical, long-lasting abrasives that may be used for a range of blasting and peening tasks.

In order to guarantee that the finished product satisfies the necessary requirements for size, hardness, and shape, the process entails a number of crucial phases. This is a summary of the production procedure:

  • Raw Material Selection

Selecting premium stainless steel scrap is the first step in the procedure. Stainless steel fragments with the correct amounts of chromium, nickel, and other components that provide the finished product toughness and resistance to corrosion usually make up this scrap metal.

  • Melting

In an electric arc furnace or an induction furnace, the chosen stainless steel scrap is melted. The melting procedure is meticulously managed.

  • The process of atomization

The liquid metal is then split up into tiny droplets by atomizing the molten stainless steel. This is often accomplished by applying high pressure to a stream of inert gas or water to scatter the molten steel into minute particles before forcing it through a nozzle. By altering the nozzle’s design and pressure, one can modify the droplets’ size and shape.

  • Solidification and Cooling

The stainless steel droplets get atomized and start to cool and harden as they come out of the nozzle. This quick cooling procedure is important because it makes the shot spherical. As the droplets pass through the chilling chamber, they congeal into tiny, spherical particles.

  • Examining and Rating

The stainless steel shot is screened and graded based on size once it has cooled. Usually, rotary sifters or vibrating screens are used to divide the shot into several size groups. To get rid of any dust or debris from the production process, the shot can also be cleaned.

  • Application of Heat

The stainless steel shot is heat treated to provide the required mechanical and hardness qualities. This could entail quenching, tempering, and annealing, depending on the shot’s particular requirements. The performance and longevity of the shot in blasting applications are improved by heat treatment.

  • Conditioning (Selective)

The shot might go through a conditioning procedure for particular applications in order to get rid of any sharp edges or abnormalities. This is especially crucial for shot peening applications, since the items being treated must not be harmed by the shot’s rough surface.

  • Examining and Arranging

The stainless steel shot is inspected as the last stage of manufacturing to make sure it satisfies all quality requirements. This could involve sphericity, hardness, and size distribution tests. After approval, the shot is packed for delivery to clients, usually in bags or drums.

Benefits of Using Stainless Steel Shot

  • Durability and Longevity: Reusability and less wear on equipment
  • Superior Cleaning Efficiency: Uniform surface finish and fffective contaminant removal
  • Environmental and Health Benefits: Reduced dust emission and non-Toxic
  • Cost-Effectiveness: Lower overall costs and energy savings
  • Versatility: Wide range of applications and various grades and sizes
  • Improved Surface Preparation: Enhanced paint adhesion and stress relief

Applications of Stainless Steel Shot

Stainless steel shot is a multipurpose abrasive medium that finds utility in various industrial settings for surface cleaning, conditioning, and finishing. Because of its characteristics, it can be applied to a wide range of materials without contaminating them. The following are some of the main uses for stainless steel shot:

Cleaning of Surfaces

  • Removal of Rust and Oxidation: This method efficiently cleans metal surfaces of rust, oxidation, and corrosion. Sand, oxide coatings, and extra metal can be removed from the surface of castings by cleaning them.
  • Sharp Peening Strengthening Stress Relief: This process creates compressive stress on component surfaces in the manufacturing, automotive, and aerospace industries.
  • Enhancing Wear Resistance: Contributes to enhancing component wear resistance and extending service life.

Surface Preparation

  • Pre-coating or Painting Preparation: Creates a clean, rough surface profile to enhance the adhesion of coatings, paint, or other surface treatments, ensuring longer service life and better performance.
  • Deburring: Effectively removes burrs from machined parts.

Shot Blasting Cleaning

  • Surface Texturing: Used for texturing metal surfaces to provide an aesthetic finish or prepare the surface for bonding with other materials.
  • Weld Cleaning: Effectively cleans and smoothens welds without damaging surrounding materials.

Scale Removal

  • Removal of Heat Treatment Scale: Particularly useful after heat treatment processes to remove oxide layers, ensuring a clean surface.

Decorative Finishing

  • Stainless steel, aluminum, and other metals can be finished uniformly, mattely, or satiny with the help of aesthetic metal finishing, which is used in architectural and ornamental applications.

Medical and Food Processing Equipment

  • Cleaning and Precision Finishing : Stainless steel shot is an excellent material for cleaning and precision finishing medical instruments and food processing equipment in order to comply with safety and hygiene regulations.It leaves no residue on surfaces and is non-toxic.
  • Aerospace and Automotive Industries: This process involves cleaning, shot peening, and precision finishing a variety of components, including gear, turbine, and car body parts, to increase their resistance to fatigue and environmental factors.
