316 Stainless Steel


Where your job requires a greater level of corrosion resistance than 304 Grade Stainless Steel (Furniture Grade) then 316 Grade Stainless Steel (Marine Grade) is the right choice for you. 316 Grade Stainless steel is similar in most respects, with virtually identical mechanical , physical and surface properties as 304 Grade, but with the superior corrosion resistance it should be considered for marine or food processing applications.


316 Grade Stainless Steel should have very low magneticity and has a high tensile strength . Welding of 316 Stainless Steel is possible, but care will be needed to clean welds and areas effected by heat decolourisation from the welding processes.

Density7,900 lg/m3
Tensile Strength515 MPa
Brinell Hardness217 HB
Rockwell Hardness95 HRB

Common Applications

316 Stainless steel will be considered in :

  1. Sea Front Building
  2. Piers, wharves & jetties
  3. Boats & Ships
  4. Factories processing chlorides and food products

Surface Preparation and Coatings

Unlike mild steel the chemistry of stainless steels means the processes and methods for protecting and finishing 316 Grade Stainless Steel are vastly different to mild steels.  Most surface finishes for stainless steel will be mechanically (Polishing) or chemically (Passivating) applied.    The correct surface finish will have substantial impacts on the performance and appearance of your stainless steel.   

One of the most important considerations for the performance and appearance Stainless Steels is cleanliness.  Surfaces need to be kept free from particles of other metals especially alloy or carbon steels.  Timber also has contaminants that will leech and stain stainless steels.

Due to the variety of finishes available in stainless steels, Edcon Steel strongly recommends you discuss your requirements with your designer or fabricator.
