How the difference between 316 stainless steel and 304 stainless steel is as follows:

Now the two most commonly used stainless steel 304, 316 (or 1.4308, 1.4408 corresponding to the German / European standard), the main difference between the chemical composition of 316 and 304 is that 316 contains Mo.

It is generally accepted that 316 is more resistant to corrosion and more resistant to corrosion than 304 in high temperature environments. Therefore, in high temperature environments, engineers generally use components of 316 materials.

316 stainless steel hex bar

316 stainless steel hexagonal bar is a widely used steel with good corrosion resistance, heat resistance, low temperature strength and mechanical properties;

Good hot workability such as stamping and bending, no heat treatment hardening.

316 Stainless Steel Square Bar

316 Stainless Steel Square bar is an austenitic chromium nickel steel square bar containing molybdenum which provides superior corrosion resistance and increased strength at elevated temperatures when compared to 304 Stainless.

Widely known as a food grade stainless or marine grade, 316 Stainless is ideally suited for corrosion resistance against a wide range of chemical and acidic corrodents, and marine environment applications.

Typical uses of 316 Stainless includes food production, pharmaceutical equipment, furnace parts, heat exchangers, valves and pumps, chemical equipment, and parts for marine use. Primarily offered in a lower carbon, dual grade 316/316L for increased machinability and added corrosion resistance when welded.

316 Stainless is moderate to weld, cut, form and machine with the proper equipment. Metals Depot stocks a wide size assortment of 316 Stainless Steel Square Bars that you can buy online in ready to ship precut or mill lengths or order just what you need custom cut to size in small or large quantity.

316 Stainless Steel Flat Bar

316L stainless steel flat bar is an austenitic chromium-nickel alloy. Its composition includes a high content of nickel and molybdenum, which gives it a higher resistance to corrosion compared to 304 stainless steel. It also has better resistance to pitting and crevice corrosion when placed in environments with chloride. This 316 alloy also has great elevated tensile and stress-rupture and creep strengths. It’s considered having excellent weldability and formability.

The applications commonly used for this alloy include food prep equipment, lab equipment, heat exchangers, boat fittings, condensers, tanks and evaporators. It is commonly used in industries like food, beverage, pharmaceutical, textile, marine and architecture. When placed in atmospheric environments, 316 alloys have a better resistance to corrosion than 304 steel because it has a higher content of chromium and molybdenum. When in temperatures above 122 degrees F and in warm chloride environments, this metal is subject to stress corrosion cracking. However, it is considered to be a marine grade stainless steel because it has great resistance in warm sea water.

316 stainless steels are also resistant to oxidation when being serviced at temperatures up to 1600 degrees F and when continuously serviced at temperatures up to 1700 degrees F. If higher resistance to carbide precipitation is needed, 316L grade steel can be used instead.

All standard fusion methods of welding can be used for this metal, either without or with filler metals. When welding heavier sections of metal, it’s recommended that post-weld annealing is done to maintain max resistance to corrosion. This isn’t a requirement for 316L grades of steel. The temperature for annealing should be between 1900 and 2100 degrees F. Heat treatment cannot be used to harden it.
