Weathering steel is a chemically formulated steel with additional alloying elements to eliminate the need for painting or polishing. On prolonged exposure to the atmosphere, it develops a protective patina layer, i.e., a rust-like appearance on its surface. This provides better strength and more corrosion resistance to the steel. The important elements in weathering steel are nickel, copper, chromium, silicon, and phosphorus. Weathering steel is used for outdoor applications where the chances of rusting are higher. It offers numerous benefits, including very low maintenance, rapid construction, attractive appearance, shallow construction depth, and long-term performance. It has widespread applications in houses, buildings, bridges, structures, heavy transport, and process industries, including heat exchangers.
How Can AI Help the Weathering Steel Market?
Artificial Intelligence (AI) can play a significant role in the weathering steel market, promoting its development and use. The major application of AI in weathering steel is to recognize its corrosion grade. Many researchers have investigated the role of several machine learning models like convolutional neural networks (CNN) and deep learning to determine the extent of corrosion. Such advanced technologies to evaluate the corrosion grade of weathering steel can save time and manpower. These are also helpful for the safety evaluation of the steel structures. Additionally, AI can predict the lifespan of the material by obtaining real-time environmental data like humidity, temperature, and pollution.

Environmental sustainability
The rising demand for environmental protection has led to the use of weathering steel in diverse sectors. Weathering steel offers environmental advantages as it neither causes problems with the paint’s volatile organic compounds (VOCs) nor the disposal of blast-cleaning debris. Additionally, the production of weathering steel requires less energy compared to other corrosion-resistant steels.
At the end of its lifespan, weathering steel structures can be dismantled, and the steel can be reused or recycled without any loss of material properties. Hence, it contributes to energy savings, resource conservation, and a decrease in the amount of waste dumped in landfills. Other weathering steel characteristics include longevity, resource efficiency, and lifecycle assessment. Thus, architects, builders, and engineers can encourage sustainable practices and create a greener built environment by using weathering steel in their construction projects.
Limited application in high saline areas
Along with several benefits, weathering steel has certain disadvantages. The major disadvantage is its limitation in a highly saline atmosphere. In marine environments, weathering steel has long wet times and is not dried. Hence, the protection layer erodes, and corrosion proceeds. Another disadvantage is its high initial cost compared to other steels. It has also disrupted supply chains, affecting growth potential.
Growing research and development
The rising demand for weathering steel in diverse sectors like construction, architecture, and transportation has potentiated interest in the innovation of weathering steel. Researchers are investigating several alloys along with copper, nickel, and chromium to increase their resistance and strength. The changing environmental conditions, like cycles of wet and dry conditions and long wetness times, demand superior quality weathering steel. Conventional weathering steel does not protect marine environments because it does not form any protective rust layer due to high atmospheric salinity. Hence, researchers are investigating the role of the mixture of various alloys like manganese and nickel that can resist corrosion in the marine environment.
The plate segment held a dominant presence in the weathering steel market in 2023. Weathering steel plates offer an extensive range of thicknesses for various applications. Plates are the thickest options and the thickness of the plate is generally 6 mm or more. They are commonly used in outdoor structural applications like bridges, buildings, sculptures, and facades. The rising construction of bridges, sculptures, etc. drives the market.
The sheet segment is projected to expand rapidly in the weathering steel market in the coming years. Weathering steel sheets vary in thickness depending on requirements and have a medium thickness range of less than 6 mm. They are widely used in bridges, railcars, and outdoor sculptures, panels, and installations.
The ASTM A588 segment accounted for a considerable share of the weathering steel market in 2023. ASTM A588 is a type of high-strength, low-alloy structural weathering steel offering exceptional corrosion resistance. They can withstand high temperatures up to 842 F. They are widely used in applications where strength and durability are required. ASTM A588 finds application in bridge construction, building facades, curtain walls, and roofing systems. Additionally, they are extensively used in outdoor structures like stadiums, pavilions, and open-air theatres.
The ASTM A242 segment is predicted to witness significant growth in the weathering steel market over the forecast period. ASTM A242 is a type of high-strength, low-alloy structure steel for structural members. They can withstand high temperatures up to 800 F. They are often used in applications where weight-savings and high corrosion resistance are required. It is commonly used carbon steel forgings used for manufacturing bolts, screws, stud bolts, nuts, and similar fasteners. They are primarily used in the fabrication of industrial air pollution stacks, air ducts of pollution control equipment, and water tanks.
The construction segment dominated the weathering steel market in 2023. Weathering steel is predominantly used in the building & construction sector. It is used for constructing bridges and houses to enhance durability and pleasing appearance. It also reduces construction and maintenance costs and lowers environmental impact. Additionally, it protects from hazardous environmental impacts like the emission of volatile organic compounds (VOCs) due to oil-based coatings. The rise in population, government initiatives, technological advancements, investments in the construction sector, and rapid urbanization drive market growth. China, the US, Japan, and India are the top four countries with the largest construction market globally.
The automotive segment is estimated to be the fastest-growing in the weathering steel market during the forecast period. Weathering steel is highly used in the automotive sector due to its strength, durability, and corrosion resistance, especially in vehicle manufacturing and railways. In railway vehicles, weathering steel offers strength, hardwearing, and the ability to take higher payloads. Hence, they provide exceptionally long service life with low maintenance costs. The strategic investments in the automotive sector augment the market. The US Federal Railroad Administration (FRA) has opened applications for $2.4 billion of funding through its Consolidated Rail Infrastructure and Safety Improvements (CRISI) program.
