Duplex Stainless Steel – A Global Market Overview

Duplex Stainless Steel Market Trends and Outlook

Duplex Stainless Steels form a specialized class of stainless steels, named for their metallurgical structure comprising two phases, viz., austenite (face-centered cubic lattice) and ferrite (body centered cubic lattice) in approximately equal ratios. Although exact proportions can vary by grade, a majority of Duplex Stainless Steels usually have a structure with 50% austenite and 50% ferrite. As a result, this type of steel gains the benefits of both austenitic and ferritic families of steel, even while rendering drawbacks to the minimum. Other common components of Duplex Stainless Steels, in varying proportions, can include carbon, manganese, silicon, chromium, nickel, phosphorous and sulfur, with molybdenum, nitrogen and copper also being utilized for further improvements, as and when required.

Duplex Stainless Steels account for a very small part of the overall stainless steel produced globally, though their range of benefits far supersede conventionally used austenitic and ferritic stainless steel grades. Primary among these include improved strength as much as two times stronger, superior toughness & ductility, excellent corrosion resistance and cost-effectiveness. Owing to these factors, the use of Duplex Stainless Steels has extended to a variety of sectors that include offshore and near-shore operations, such as oil drilling, desalination, water treatment & other industrial operations, chemical & liquid processing, pulp & paper production, construction and automotive & marine parts & components. The global demand for Duplex Stainless Steel is estimated at US$4.4 billion in 2024 and is projected to reach US$6 billion by 2030 at a CAGR of 5.4% between the two years.

Emerging markets and regions experiencing rapid industrialization have been the major drivers for Duplex Stainless Steel demand. The investments by these regions in the areas of oil & gas, chemical processing and infrastructure have propelled the demand for this unique variety of steel that can withstand the harsh operating environments of these sectors. The oil & gas industry has been, and will continue to be, the major driver for Duplex Stainless Steel demand. The higher strength and toughness, coupled with outstanding corrosion resistance, of this variety of stainless steel, allow it to be most extensively used in this critical sector of the economy. Other than this, Duplex Stainless Steel is also widely employed for construction and chemical applications because of the same advantageous features, with bridges and other buildings being major consumers of Lean Duplex Stainless Steel. The number of infrastructure projects across the world has been growing at a steady pace, owing to which the benefits offered by Duplex Stainless Steels have enabled their replacing traditional austenitic and ferritic stainless steels. Other factors likely to drive growth for Duplex Stainless Steels include developments in manufacturing techniques, compositional alterations for better product quality and surface treatments that enhance product durability, opening the doors for newer applications. As production processes improve and get streamlined, the overall cost of production also gets reduced, thereby increasing final output.
