How can you tell if stainless steel is 304?
Stainless 316 is made up of 16% chromium, 10% nickel and 2% molybdenum. The two steel grades are comparable in appearance, chemical makeup and characteristics. Both steels are durable and provide excellent resistance to corrosion and rust.
This makes grade 316 stainless significantly fascinating for purposes the place exposure to salt or different powerful corrosives is a matter. Ferritic stainless steels possess a ferrite microstructure like carbon metal, which is a body-centered cubic crystal construction, and comprise between 10.5% and 27% chromium with little or no or no nickel. This microstructure is current in any respect temperatures as a result of chromium addition, so they are not hardenable by heat remedy.
The pulp and paper trade was one of many first to extensively use duplex stainless-steel. Today, the oil and gasoline business is the biggest person and has pushed for extra corrosion resistant grades, resulting in the event of super duplex and hyper duplex grades.
However, the closer grade 304 chrome steel reaches its melting level, the extra tensile strength it loses. Type 316 steel is an austenitic chromium-nickel chrome steel that contains between two and three% molybdenum.

Our stainless production range
- Stainless steels have a protracted history of utility in contact with water as a result of their wonderful corrosion resistance.
- However, with rising chloride contents, greater alloyed stainless steels similar to Type 2205 and tremendous austenitic and tremendous duplex stainless steels are used.
- Types 304 and 316 stainless steels are standard materials of building in contact with water.
- Applications include a variety of circumstances including plumbing, potable water and wastewater therapy, desalination, and brine therapy.
When it comes to applications with chlorinated options or exposure to salt, grade 316 stainless steel is taken into account superior. For instance, duplex stainless steels are utilized in digesters to transform wooden chips into wood pulp. 6% Mo superaustenitics are used in the bleach plant and Type 316 is used extensively within the paper machine.
Grades Of Duplex Stainless Steels
Even though grades similar to 304 and 316 stainless-steel have high quantities of iron in their chemical composition, austenite means they are non-ferromagnetic. However, if the crystal structure of an austenitic stainless steel is changed by way of work-hardening or special thermal treatment, then ferrite can kind in some areas making the metal partially magnetic. The elevated nickel content and the inclusion of molybdenum allows for grade 316 stainless steel to have better chemical resistance than 304 stainless-steel. It’s capability to resist acids and chlorides, including salt, makes grade 316 perfect for chemical processing and marine purposes.
Thus, austenitic stainless steels usually are not hardenable by heat treatment since they possess the same microstructure at all temperatures. Austenitic stainless steels have a high amount of austenite which makes them mostly non-magnetic.
General Properties
Resistance to different gases relies on the type of gas, the temperature, and the alloying content of the chrome steel. Duplex 2507 is a super duplex stainless steel designed for applications which demand exceptional energy and corrosion resistance. Alloy 2507 has 25% chromium, four% molybdenum, and 7% nickel.
What is the difference between duplex and super duplex stainless steel?
Duplex stainless steels are based around a composition of 22% chromium, whereas super duplex stainless steels are based around a composition of 25% chromium. By increasing the chromium content, the level of pitting corrosion resistance is also increased.
