What makes 904L better than 316L stainless steel pipes?
904L is better than 316L for harsh environments due to its superior corrosion resistance, specifically in chloride-rich conditions and strong acids, thanks to its higher nickel, molybdenum, and copper content. While 316L is suitable for general applications and is more cost-effective, 904L is the preferred choice for demanding situations like marine environments, chemical processing plants, and flue gas desulfurization systems where 316L may fail.
Market Analysis: Why 904L is in High Demand (2025)
The global chemical processing industry is driving increased demand for acid-resistant stainless steel pipes.
Energy transition projects (hydrogen, desalination, offshore platforms) prefer 904L due to its chloride resistance.
In 2025, the average price per kg of 904L has risen slightly (about 3–5%) due to higher nickel prices.
Major consuming regions include Europe, the Middle East, and Southeast Asia, with growing procurement for heat exchangers and marine systems.
