These tough, useful forms of stainless steel are called Duplex because of the double micro structure within them. Inside this [url=http://www.achbanker.com/home.php]www.achbanker.com/home.php[/url] unimposing material is a structure which consists of grains of ferritic stainless steel as well as austenitic grains in between. [url=http://www.sandvikfw.net/shopuk.php]hollister sale[/url] When this type of steel is melted and then re-solidified, it becomes a completely ferritic structure. When [url=http://www.rtnagel.com/airjordan.php]jordan pas cher[/url] the steel returns to room temperature around 50% of the grains reform into islands of austenitic grains, creating a ?duplex? microstructure of half and half.
Because of this unique structure, these types of stainless steels are a popular choice for many types of manufacturing and other applications, due to their attractive and [url=http://www.1855sacramento.com/peuterey.php]peuterey outlet[/url] useful [url=http://www.getconversational.com]hollister pas cher[/url] properties.
The first of these is the strength of the steel. In tests Duplex steels have been shown to be around twice as strong [url=http://www.vivid-host.com/barbour.htm]barbour uk outlet[/url] as regular steel, making them the perfect choice for load bearing structures or in areas of high pressure or weight.
As well as this, duplex steel are tougher and more [url=http://www.getconversational.com]hollister france[/url] ductile than [url=http://www.hanesmorgan.com]hollister outlet[/url] ferritic steels, meaning they are less likely to crack under stress and strain. However, the austenitic steels still reach higher grades on these characteristics, although they do not perform as well in some other areas.
Stainless steel is often picked for projects due to its corrosion resistance, however the composition of the steel itself can be a highly influencing factor in the materials level of resistance in the long run. Duplex stainless steels perform in a similar manner to the austenitic stainless steels making them excellent durable materials capable of standing up to harsh environments.
Standard austenitic stainless steels [url=http://www.rtnagel.com/airjordan.php]nike air jordan pas cher[/url] perform well in terms of corrosion resistance and ductility, but let themselves down when it comes to stress corrosion cracking resistance. In particular conditions, such as humidity, high temperatures and in the presence of certain chemicals, these stainless steels have been found to crack and weaken as a result of the environmental stresses. Duplex stainless steels outperform austenitic in this category [url=http://www.achbanker.com/home.php]hollister france[/url] by a mile, as they seem to have inherited the excellent [url=http://www.gotprintsigns.com/uggpascher/]bottes ugg pas cher[/url] resistance from their ferritic side.
Because duplex stainless steels have lower concentrations of expensive alloys in their make up than other materials which perform in a similar fashion, they can work out to be substantially cheaper and more than capable of doing an excellent job.
