Today, you can easily find different types of steel that can be used for a variety of purposes in the market. Amongst these types is the stainless steel, which is known as one of the finest. A steel is called stainless when it has chromium on it. Chromium is the element that steel resistant to corrosion. The list of properties on stainless steels means a number of benefits.
Among the most widely used types of stainless steel is duplex stainless steel. Apart from the high level of corrosion resistance, duplex stainless steel also exhibits elevated disputation to inter-granular breakdown. In addition, duplex can withstand an environment with chloride. And like other types of super duplex stainless steel, duplex is also immune to stress corrosion cracking.
Duplex stainless steels are called as duplex because of their dual phase micro-structure of ferritic grains and austenitic stainless steel. When you melt a "duplex," you coagulate the steel from its fluid form to a fully ferritic structure. During the cooling process, almost half of the grains convert to austenitic ones, which leads to the roughly half-half micro-structure composition of the duplex.
This structure provides the stainless steel family a mixture of the following striking properties:
Power - the dual configuration of duplex stainless steel makes it twice stronger than regular types of stainless steel.
Extremely high level of resistance to corrosion - The level of corrosion resistance of all stainless steels lies primarily in the make-up of the steel. Duplex stainless steel has a high level of contention to corrosion because it contains elements like chromium, molybdenum and nitrogen.
High level of resistance to stress corrosion cracking. Unlike regular austenitics steels that cannot function well in a damp, chloride-filled environment, "duplex" manifests a very strong stress corrosion cracking resistance, thanks in large to its ferritic composition.
Cheaper than other stainless steel - even with the super power of duplex steel, it is actually less expensive than other kinds of steel because it needs a little alloy content. This property is financially beneficial to businesses revolving around marine environment because aside from copper nickel, duplex steels are widely traded in this business.
Duplex stainless steel is used for many purposes, by many companies around the world. Some of the most popular uses of this kind of steel include processing of chemicals, refining of gas and oil, pulp manufacturing, and marine pipe supplier enterprise.
