304SS vs 316SS

304SS vs 316SS, 304SS vs 316SS

With its chromium-nickel content and low carbon, is the most versatile and commonly used of the stainless steels.  Type 304 proves to be resistant to oxidation and corrosion. Type 304 stainless provides ease of fabrication and cleaning, prevention of product contamination and offers a variety of finishes.  The 304 stainless steel is used in enclosures, storage tanks, pressure vessels and tubing or piping.Stainless steel is chromium-nickel stainless and heat-resisting steel with superior corrosion resistance as measured up to other chromium-nickel steels when exposed to many types of chemical corroding elements. Buyers may find that the upfront cost is a little higher but could save a lot on the back end which is something to keep in mind when purchasing.

Given that Type 316 stainless steel alloy contains molybdenum it has a considerable more resistance to chemical attack than 304. Type 316 is durable, easy-to-fabricate, clean, weld and finish. It is considerably more resistant to solutions of sulfuric acid, chlorides, bromides, iodides and fatty acids at high temperature. Stainless steels containing molybdenum are required in the manufacture of certain pharmaceuticals in order to avoid excessive metallic contamination.

304SS vs 316SS is a common asked concern and question that customer ask SRS.  In metallurgy, stainless steel, also known as inox steel or inox from French inoxydable, is a steel alloy with a minimum of 10.5% chromium content by mass.   Stainless steels are notable for their corrosion resistance, which increases with increasing chromium content.

Grades of 304ss vs 316ss

Additions of molybdenum increase corrosion resistance in reducing acids and against pitting attack in chloride solutions.

Thus, there are numerous grades of stainless steel with varying chromium and molybdenum contents to suit the environment the alloy must endure.


Stainless steel’s resistance to corrosion and staining, low maintenance, and familiar luster make it an ideal material for many applications.  Applications where both the strength of steel and corrosion resistance are required.
