Corrosion Resistance: Benefits Of Duplex Stainless Steel

By Celine Nguyen


Properties Of Duplex Stainless Steel.

Stainless steel is a type of steel combined with the alloying material chromium. It is extremely popular due to its various uses nowadays. Depending on the presence of other alloying materials, diverse stainless steel families have different properties. Among the top known stainless steel families are the ferritic, austenitic and duplex stainless steel. Austenitic stainless steel is mechanical, flexible and formable, but less rust resistant. Ferritic stainless steel is less mechanical however more proof against corrosion. Duplex is a mixture of both.

Duplex stainless-steel is called duplex because it consists of a two-phased microstructure that results with the lessened amount of nickel in the composition. It consists of both ferritic and austenitic structures- thus both austenitic and ferritic properties as well. It has the strength and mechanical properties of austenitic stainless steel and the rust resistance of the ferritic stainless steel. It can be welded and formed, and also exhibits high yield potency and resistance to chloride exposure, crack decay, pitting and stress deterioration cracking.

The superior properties of duplex stainless steel really impacts a number of industries due to its lesser fabrication overheads. Duplex steel is twice the strength of regular austenitic stainless-steel, which makes it workable for contractors to reduce the material thickness without compromising the price and quality of the product. The lower quantity of alloying contents cause them cheaper than other materials that prevents corrosion.

Stainless Duplex Steel: Applications.

The superior yield potency and better rust resistance properties of duplex stainless-steel yield them perfect for specific industries and sectors that deal with chloride rich environments. Duplex steel is commonly used in numerous chemical and food processing industries. Its properties create a necessary material from the shipbuilding sector. It's used to construct different types of maritime vessels. Amongst these crafts are tug boats, fishing vessels, luxury yachts, liners, chemical tankers, and a lot more.

The higher yield vigor combined with the outstanding strain and pitting rust resistance of duplex stainless steel has improved the popularity and use of the material significantly since its induction in the early 90's. Continuous exploration and development aims to enhance its response to heat and other elements. One could securely conclude that the duplex stainless steel will remain useful to humanity.
