Duplex Stainless Steel

It took Ramdevra Metal Industries many years of constant trials & errors, before gaining a complete control over this steel. The dual phase structure demands a perfect balance in the chemistry of these steels. Duplex Stainless Steel also show an irregular behavior when undergoing various hot working processes.

But thanks to the strong determination of our Research & Development team, as Ramdevra Metal Industries now enjoys the reputation of being one of the most reliable Manufacturerof Duplex stainless steel materials in domestic as well as the international market.

EXCELLENT QUALITY DUPLEX STAINLESS STEEL WITH HIGH MECHANICAL STRENGTH!

Duplex Stainless Steel Long Products are the family of steels that have a mixed micro-structure of 50% ferrite and 50% austenite. They are known to offer exceptional strength and astounding aesthetic qualities along with better resistance to corrosion and high temperature, superior hygienic surface finishing, and improved steel recyclability.

At Ramdevra Metal Industries, we are committed to ensuring the development of highly sustainable long products that meet the expectations and requirements of our clients. As a result of our drive to continuously improve and transform our products

we manufacture customized duplex stainless products in our ultra-modern production facilities in multiple grades and sizes. By leveraging the expertise of the team of experts, we develop a wide range of corrosion-resistant duplex stainless steel products that maintain a uniform size and surface tolerance in diverse environments.
