Duplex Steel Sheet Manufacturers In India | Astm A240, Asme Sa240 & En Sheets

Neptune Alloys is a leading Duplex Steel Sheet Manufacturer that produces high performance stainless steel sheets to be used in chemical processing, marine engineering, offshore platforms, oil and gas industries and pressure vessel applications. Duplex Steel Sheets are a combination of austenitic and ferritic stainless steels, with great mechanical strength and high resistance to stress corrosion cracking, pitting, and crevice corrosion. These sheets are more popular in harsh conditions when durability and corrosion resistance are of high importance, as well as long-term performance. They also have a high strength-to-weight ratio, which contributes to the minimization of material consumption in the industrial projects.

Duplex Steel Sheets can be sourced by industrial buyers and engineering contractors on a reliable B2B platform with customized dimensions, thicknesses, finishes, and meeting international standards. Such sheets come in different grades such as UNS S31803 and UNS S32205 to suit the industrial needs. Produced through intensive production procedures and quality controls, Duplex Steel Sheets provide consistent performance in harsh working environments and offer high weldability and fabrication as well.

Material & Weight Chart of Duplex Steel Sheet

Duplex Steel Sheets are offered in a variety of thickness and dimension as per ASTM specifications. Common sizes and approximate weights are given in the table below.

Duplex Steel Sheets find wide applications in desalination plants, storage tanks, heat exchangers, offshore structures and chemical processing equipment where outstanding corrosion resistance and mechanical strength is necessary. Their capability to tolerate the severe chloride-based conditions makes them a desirable choice in the critical industrial application. In addition to special duplex grades, the standard Sheet products are also applied in manufacturing fabrication, construction, process industries, and engineering projects where durability, versatility and reliable performance are required.
