What is Super Duplex 2507 Fasteners ?

These Super Duplex 2507 Fasteners have equal concentrations of austenitic as well as ferritic nature in their chemical composition. These fasteners are highly resistant to corrosion-related corrosion pitting and corrosion cracking and are comparatively more preferred than the 300 series fasteners. These fasteners come under the super duplex steel grade.

Super Duplex 2507 Fasteners have a chemical composition that is composed of 25 percent chromium, 4 percent molybdenum and 7 percent nickel. They can also withstand chlorine bound environments. Therefore, these Super Duplex 2507 Fasteners are widely used in seawater applications as well as off the shore applications. These fasteners also contain a certain concentration of nitrogen in their alloy, which thus makes them comparatively harder than the other fasteners.

India’s specialist Super Duplex 2507 Bolts & Super Duplex Stud Bolts, Super Duplex Nuts and Bolts, super duplex fasteners Manufacturer India.

Sumit Impex aims at providing the best quality Super Duplex 2507 Fasteners. These fasteners could be available in different shapes, sizes and dimensions depending upon the user requirements or the specifications provided for the required application. These fasteners can also withstand various acidic mediums.

The chromium, nickel and molybdenum combination helps in improving the mechanical characterization of the alloy and thus improve the quality of the fasteners. These Super Duplex 2507 Fasteners can be used in an environment bound with elevated temperatures, or an atmosphere that could lead to corrosion or an atmosphere that could create damage with respect to pressure; because of all of the properties that these fasters have, they are used in a large number of industries such as the paper and pulp industries, oil industries, gas industries, etc.

Application Industries

These material are not a single material but the name for a family of corrosion resistant steels. Like many scientific breakthrough the origins of stainless steel lies in a lucky accident. From the smallest part of zipper to the largest building skyscraper, stainless steel is an essential part of modern life.Stainless steel’s strength, resistance to corrosion and low maintenance make it the ideal material for a wide range of applications. It is also has a long life cycle and is 100% recyclable.
