Shot Blasting Abrasive

Shot blasting is an essential procedure in various industries for surface preparation or cleaning metal and other surfaces. To understand shot blasting abrasive better, let’s delve into its various aspects, from the types of abrasives used to its applications.

What is Shot Blasting?

Shot blasting is a process wherein abrasive media, often called “blasting media” or “blast media,” is propelled at high velocity onto a surface. This action cleans or prepares the surface for coatings, painting, or other treatments.

The bombardment cleans the surface by removing contaminants like rust, old paint, scale, and dirt, leaving it ready for further treatments.

Additionally, shot blasting creates a slightly roughened texture, ideal for improving the adhesion of paints, coatings, and other bonding materials. It can also create decorative finishes, a peened surface for better fatigue resistance, or a specific surface profile for specialized applications.

This process is commonly used in industries like automotive, construction, aerospace, and foundries.

Types of Shot Blasting Abrasive:

  1. Steel Shot & Steel Grit: Durable and recyclable, steel abrasives are used for blasting heavy-duty parts, offering a smooth finish.
  2. Glass Beads: These provide a bright, satin-like finish, ideal for soft metals.
  3. Aluminum Oxide: Known for its hardness and aggressive cutting properties, it’s suitable for surface etching.
  4. Walnut Shells: A softer abrasive, perfect for delicate parts and ideal for removing paint without damaging the underlying surface.
  5. Garnet: Natural and sharp, garnet is used for both blasting and water jet cutting.
  6. Sand: Once a common abrasive, its use has diminished due to health concerns, but it’s still applied in certain applications.

Choose from a wide range of shot blasting material

  1. Steel Abrasives: This tough and highly recyclable abrasive is the cost-effective choice for steel shot blasting.
  2. Stainless Abrasives: Ideal for non-ferrous metals and stainless steel, these iron-free abrasives ensure a clean surface.
  3. Premium Media: Combine premium steel products with superior service for exceptional quality, performance, and cost savings.
  4. Cut Wire: Extremely durable and made from various alloys, cut wire is the top choice for peening applications.
  5. Non-Metallic Abrasives: Choose from a wide range of options, from softer plastics to glass beads for smooth finishes, all the way to the hardness of aluminum oxide.
  6. Peening Media: Enhance your shot-peening process with media specifically designed for optimal stress levels and surface integrity preservation.

How to choose the right blasting media for your needs

  1. Surface Material: Match the media’s abrasiveness to the workpiece material. Harder media like steel shot is ideal for cleaning tough surfaces like steel, while softer options like plastic beads are gentler for delicate materials like aluminum.
  2. Surface Preparation Needs: Do you need to remove heavy rust or just a light layer of paint? More aggressive media tackles heavy-duty cleaning, while finer options create a smoother finish for painting or adhesion.
  3. Desired Surface Profile: A rougher profile improves adhesion, while a smoother one might be needed for aesthetics. Different media types create varying degrees of roughness.
  4. Environmental Considerations: Some media like glass beads generate minimal dust, making them ideal for enclosed spaces. Biodegradable options might be preferred for environmentally conscious projects.

Stainless Steel Shot & Grit

GRITTAL

GRITTAL is the economic alternative to mineral grit abrasives and fulfills all requirements concerning blasting performance and a corrosion-free surface finish.

GRITTAL offers additional clear economical and environmental advantages. The extremely high durability of this rust-free stainless steel grit reduces the amount of abrasive consumption by a factor of 30 – 100 and thereby also minimizes the amount of waste that is generated.

The durability of GRITTAL results in a consistent work mix, constant roughness values and guarantees a quality adhesion for an ensuing coating.

GRITTAL’s dist-free characteristic allows for an excellent vision while blasting and helps to better control the blast process.

GRITTAL is successfully used in blast rooms and also in centrifugal wheel blast machines.

GRITTAL SCREEN ANALYSIS

Rust proof, angular chromium alloy grit (hardened and crushed)
Chemical composition: C = 2%, Cr = 30%
Microstructure: Martensite with chromium carbides
Hardness: GH ~750, GM ~640
Apparent density: = 4.1 kg/dm3

CHRONITAL

CHRONITAL is used in all applications where non-rusting materials such as aluminum, zinc, stainless steel, brass, bronze, etc. are blasted.

CHRONITAL’s large spectrum of grain sizes makes it well suited to cleaning, de-burring, hardening and surface finishing of all types of castings, forgings, profiles, wire and welded structural parts, without the possibility that rust could discolor the bright surface due to ferritic dust.

CHRONITAL distinguishes itself by having a high percentage of spherical grains and by its compactness. The end result is low consumption, high performance and low machine wear.

The danger of developing ugly rust spots on the surface of blasted concrete and granite stones due to the remains of ferritic particles is ruled out. Using CHRONITAL on smooth and textured pavers brings out the stones fascinating optics in a favorable way.
