Chromium is the shared metal used to generate this type of steel.  It is what enables the metal to work under harsh temperatures and circumstances.  It ensures the steel remains intact under physical accounts of highly pressurized situations, effectively manages transporting gases and liquids, and is the ideal option for food processing functions evading contamination.  A minimum of chromium is required for it to perform properly, which is 10.5%.  Other materials used to construct this heavy-duty steel are nickel, manganese and nitrogen.  It is also known to be 100% recyclable due to its ability to be smelted and completed into something else.  This is why it is such a desirable metal to work with for numerous commercial and residential projects in the engineering, architectural, business industries and more.

How to Identify Quality Stainless Steel

Posted on February 16, 2012 by Reda Abouleish

stainless-steel-nickel-alloy-bars-metal-propertyWhen purchasing stainless steel for your next project or business, examine the metal properties.  Ask about the stress, strain and stiffness.  These three traits need to be considered when you buy stainless steel.  Ask the manufacturer to breakdown what these properties mean and how they play a significant role.  In the meantime, here is a brief outline of what these traits entail.


When examining the stress of a metal you are deliberately looking to see how far you can stretch or pull the metal before the cross-section starts to unravel.  By doing so, one reveals if there are any holes or sudden changes in the cross-section. This is valuable information.  Stainless steel is known to be a dependable, tough and rust-resistant material; thus, if you bought a defective piece then disaster ensues.  Avoid the negative pitfalls of buying cheap steel by asking the seller about the level of stress the metal exhibits.


Think about what happens when you bend any piece of material.  Does it snap into two pieces once it reaches a certain point?    If so then the stiffness level is, most likely, quite low.  On the other hand, if the metal bends but does not snap then the material may rate high on the stiffness trait.  This is important to be sure your choice of metal does not fall apart or break when extreme pressure is applied.


Strain is defined as how much a material is compressed or stretched in comparison to its original length.  For instance, if you take a titanium rod and stretch it to be twice its original strength then the strain of the rod would be 100% an engineering strain.  Another test to check strain is a compression test.  This entails taking the metal between two plates and applying force by moving the crossheads together. This examination governs the strength, proportional limits, and its elasticity range.
