Duplex Steel Sheet
What is a Duplex Steel Sheet?
Duplex stainless steel is called so for its two phases: an austenite phase and a ferrite phase. The chemical composition of this high-tech steel consists of: Chromium, Nickel, Nitrogen, Molybdenum, Vanadium. Duplex stainless steel tends to be solidified by heating from the liquid phase to a mature solid consisting of ferritic grains. The melting point of the mixture is only about halfway to the point at which a 50% residential development in the ferritic grains can be established. This results in a microstructure consisting of roughly 50% austenite and 50% ferrite.
What are the properties of Duplex Steel Sheets?
Sheets made from duplex stainless steel have a vast array of unique properties.
Increased resistance against crevice, pitting, and stress corrosion cracking.
Two types of steel, ferritic and austenitic, have exceptional mechanical strength and excellent toughness.
Very good weldability, which may be applied to larger cross-sections.
It can be used at temperatures up to 300°C.
Tips to find a trustable Duplex Steel Sheet supplier in India
To identify an authentic duplex steel sheet supplier in India, you should consider these tips:
- Look for Duplex Stainless Steel Sheets providers that have actually been in existence for some time in order to maximize the level of expertise as an outcome. Also, make sure you have looked at their certifications, to confirm that they have met the minimal requirements for the level of quality.
- Ask for the stock information of Duplex SS sheet size and finishing, whichever is applicable to your situation. They ought to have enough stock among their appliances to ensure that you can acquire the sheets you require, without delay.
- Read about the firm online and read past client testimonials. Try to find out whether the business is transparent in their dealings with clients. Look at their client servicing both online and offline.

Benefits of Duplex Steel Sheets
Affordability
Duplex stainless steel sheets are less expensive than commonly anticipated, particularly 304 stainless steel.
Maintenance
A special steel sheet is simple to clean.
Nonmagnetic
Although a number of stainless steel types are magnetic, austenitic stainless steels are generally not.
Versatility
Steel makers can blend this alloy into a precisely measured proportion of components and use this steel alloy to give sheets that are elastic and have unique properties. The thickness of the sheets varies, sometimes reaching a quarter of an inch.
