How to Evaluate Nickel Alloys

Choose machinery made from nickel alloys and stainless steel.

When purchasing nickel alloy bars it is important to keep a checklist of what different traits you need to examine.  Think about the magnetic properties, oxidation and sulfide endurance, the ability to hold up under extreme weather, the hardness of the chosen metal and the rust resistance.   These are all important characteristics to look at when choosing stainless steel or nickel alloys.  But today I am going to be focusing on two qualities that stand out the most: mechanical properties and erosion resistance.

Mechanical Properties

Before putting in an order, talk to a nickel alloy expert about what diverse temperatures the metal performs well in.  You need the product to work effectively whether it is positioned in a room emitting extreme heat or one maintaining consistent, comfortable room temperature.  The operation of the metal should not change.  This is essential to your business operations.  You cannot have machinery suddenly stop functioning due to a temperature change.  A breakdown of equipment puts a dent into your earnings and forces you to use it for repairs.

Erosion Resistance

Using a type of material that cracks, falls apart and rusts is a problem.  These defects affect the entire success rate of a business.  You cannot keep stopping and starting whenever something breaks down. Having a reliable, strong, erosion resistant material keeps your work moving along smoothly.

How to Identify Quality Stainless Steel

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.
