Stainless steels containing molybdenum are required in the manufacture of certain pharmaceuticals in order to avoid excessive metallic contamination. Type 316 is durable, easy-to-fabricate, clean, weld and finish.ģ16 stainless steel is considerably more resistant to solutions of sulfuric acid, chlorides, bromides, iodides and fatty acids at high temperature. Given that Type 316 stainless steel alloy contains molybdenum it has a considerable more resistance to chemical attack than 304. Type 316 stainless steel is an austenitic 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 corrodents.īuyers may find that the upfront cost is a little higher but could save alot on the backend which is something to keep in mind when purchasing. Type 304 stainless steel is used in enclosures, storage tanks, pressure vessels and tubing or piping. Type 304 stainless provides ease of fabrication and cleaning, prevention of product contamination and offers a variety of finishes. Type 304 proves to be resistant to oxidation and corrosion. Type 304, with its chromium-nickel content and low carbon, is the most versatile and commonly used of the austenitic stainless steels. 278 products Stainless steel tubing is corrosion- and chemical-resistant against many caustic chemicals, environmental contaminants, corrosive fluids, oils, and gases. The molybdenum is added to help resist corrosion.
Characteristics: 316 stainless steel tubing is more resistant to corrosion and pitting than 304 stainless steel and offers higher strength at elevated temperatures.
From a chemical or scientific standpoint the answer would be that 304 stainless steel contains 18% chromium and 8% nickel while 316 contains 16% chromium, 10% nickel and 2% molybdenum. 316 Stainless Tubing Applications: 316 stainless steel can be found in pumps, valves, textile and chemical equipment, pulp & paper and marine applications.
