Duplex Stainless Steel is an almost faultless combination of the two most in-demand and best types of stainless steel viz., Austenitic Stainless Steel and Ferritic Stainless Steel. Austenitic grades of Stainless Steel are known for their incredible corrosion resistance which comes from the addition of molybdenum and chromium. Ferritic Stainless Steel grades are known for their superior strength, sturdiness, and reliability. Combined, they form the “Duplex Stainless Steel” range which is widely used by industries that require strength as well as brilliant corrosion resistance from a component at the same time.
Over the years, scientists have made developments in the chemical composition of duplex stainless steel and have found the improvised and enhanced variant of the Duplex grade known as “Super Duplex Stainless Steel”. Super duplex SS is twice as strong and resistant to corrosion when compared to Duplex Stainless Steel grades.
Just like every grade of stainless steel, even duplex stainless steel is used to forge an endless number of components used in numerous factories, industries, and varying sectors. Stainless steel of the Super Duplex type is used to make Bars, rods, fasteners, wires, etc.
Applications and benefits of using Super Duplex Fasteners:
- Super Duplex Stainless Steel 304 Fasteners are highly resistant to all forms of corrosion. Even in severe chloride-containing conditions, fasteners forged out of Super Duplex SS will stay strong
- Thus, due to this incredible corrosion resistance displayed by Super Duplex SS, the fasteners are used in heavy gauge applications that are potentially at high risk of corrosion caused by constant exposure to corrosive media.
- Super Duplex SS fasteners do not give up even under extreme pressure forces and conditions. They act as a great foundation for the structures they are used in.
- Although visually small in size, a Super Duplex SS fastener has high-impact applications. in a complex as well as in a simple piece of machinery, Fasteners play a highly important role of being the support system to the structure.
- Thus, due to these qualities such as maximum corrosion resistance and irreplaceable strength, Super Duplex SS fasteners are used for applications such as:
Seawater applications
Offshore drilling
Aerospace equipment
Shipbuilding
Chemical industries deal with hazardous and highly concentrated acids, etc.
