Stainless steel castings essential for global infrastructure

Cast stainless steel is gaining rapid traction in infrastructure development and other applications, given its inherent advantages, including high strength-to-weight ratio, corrosion resistance, longer life, and low maintenance costs. This is according to Snehal Jadhav of Global Market Insights.

“The alloying elements in stainless steels gives them several beneficial properties, such as high resistance to corrosion and heat. One of the key indicators of stainless steel is a chromium concentration of at least 10.5%. The chromium in the alloy gives the material its strength and corrosion resistance by producing a passive layer when exposed to oxygen in the air. This layer creates a barrier against further corrosion, thereby preventing the creation of rust and allowing the product to remain spotless in appearance, even under normal working conditions for prolonged periods.”

“Stainless steel is also known for its robust environmental benefits, often touted as an exceptionally green material. In the construction domain, for instance, the recovery rate of stainless steel is nearly 100%. The material is also environmentally inert and neutral, with its longevity making sure that it complies with the requirements of sustainable construction projects. Also, unlike some other materials, stainless steel does not leach compounds that could affect its composition upon contact with water or other elements.”

“Cast stainless steel is also known for its aesthetic appeal, easy maintenance, high durability, hygienic nature, and other characteristics. Consequently, it plays a key role as a component across a vast array of industries, ranging from building, to food, to medicine, to energy, to transportation, and more. The global iron and steel casting market size is projected to reach USD 213 billion in annual value by 2027, indicating a sustained demand for products like cast stainless steel components.”

Stainless steel castings in infrastructure applications
“Investments in infrastructure such as sewage and wastewater treatment facilities, offer opportunities for cast stainless products. Recent years have observed a significant boom in investments in infrastructure development. In particular, waste management and water infrastructure have gained interest of late, both in developed and emerging economies.”

“Meanwhile stainless steel, titanium and special alloys producer Sandvik launched its new grade of stainless steel, dubbed Sanicro 35, which was created as a means to reduce the performance gap between stainless steel and pricier nickel alloys. Designed to withstand seawater applications and highly corrosive environments and with several beneficial properties like superior corrosion resistance, greater structural stability, and robust mechanical yield strength, Sanicro 35 was suited for hydraulic and instrumentation tubing and heat exchangers.”

Strategic initiatives
“With the focus on construction and infrastructure advancement growing stronger over time, the casting market is becoming increasingly competitive. Many prominent players are engaging in strategic activities like focused R&D activities, acquisitions, partnerships, and production expansions to sustain a strong position in such conditions.”
