Product Description

High-Quality Stainless Steel Seamless Tubes Pipes Shot Blasting SurfaceShot blasting or peening Stainless Steel?

You would think that stainless steel is exactly that - stainless.  What makes stainless steel stainless? In a word, chrome. Stainless steel is an alloy of iron with a minimum of 10.5 percent chromium. Chromium produces a thin layer of oxide on the surface of the steel-the "passive" layer-that prevents surface corrosion.  When shot blasting/peening with a steel media, the carbon steel media used embeds contaminants into the stainless steel.    Unprotected carbon steel rusts when exposed to air and moisture. This iron oxide film (rust) is "active" and accelerates corrosion by making it easier for more iron oxide to form. 
 
One way to eliminate this issue, is to blast/peen the stainless parts with stainless steel media.  By doing this, no contaminants are embedded into the stainless part, and thus, no rusting.  However, only stainless steel parts can be blasted in stainless steel media.  Should you blast a carbon steel part in stainless steel media, you will contaminate your media, which will in turn contaminate future stainless parts.  Stainless steel media is very expensive in comparison to carbon steel media, so most mass finishers do not have machines loaded with stainless steel media, and if they do, the price reflects this as they are limited in the jobs they can run in that machine.
 
Another method to solve this issue is passivation.  In stainless steel, passivation means removing the free iron from the surface of the metal using an acid solution to prevent rust. When the surface iron is removed, the other components of the alloy (primarily chromium, often nickel as well) are left behind as a surface layer over the underlying steel. Upon exposure to air, these elements react with oxygen to form an oxide layer that protects the rest of the steel from corrosion. solutions, bleach or salt (oceanic environments) all will contribute to the need for passivation of the stainless steel.

Shot Blasting Transforms Materials for Unmatched Quality

Benefits of Shot Blasting

  • Reduces metal fatigue
  • Increases corrosion resistance
  • Descales surfaces (removing heat treat scale)
  • Deflashes die castings
  • Add texture for increased adhesion
  • Increases texture for functionality
  • Produces a uniform cosmetic finish

Packaging & Shipping
High-Quality Stainless Steel Seamless Tubes Pipes Shot Blasting SurfaceHigh-Quality Stainless Steel Seamless Tubes Pipes Shot Blasting Surface
  1. All of our stainless steel seamless pipe & tubes are packaged as per international standard to prevent any possible damage or loss. By default, we will use thick woven plastic bag to bundle the finished pipes together in batches.
  2. For some special pipes & tubes that are vulnerable to dirt, scratches, stress or rough handling, we will suggest wooden case for protection. Kindly note, wooden case can incur extra cost, not only its own cost, but also the increased freight cost, which is especially true for air transportation.
  3. For enhanced customer experience, we also provide dedicated package as per your special requirements.
Certifications
