The highly alloyed ASTM A182 Gr. F904L is rich in costly ingredients like molybdenum and nickel. However, the majority of applications utilizing ASTM A182 F904L are now being replaced by the cost-efficient duplex stainless steel 2205. Despite this, A182 F904L flanges exhibit excellent resistance to warm seawater and chloride attack. This resistance is attributed to its high nickel content, which also grants it high resistance against stress-related corrosion cracking. Additionally, the inclusion of copper in the material enhances its resistance to sulfuric acid and other reducing agents in various environmental conditions. Manufacturers of 904L stainless steel flanges emphasize that the alloy is non-magnetic and possesses excellent toughness, formability, and weldability. While it offers good resistance to oxidation, its structural stability diminishes at temperatures exceeding 400°C. However, the grade can be solution heat-treated at 1090 to 1175°C, followed by rapid cooling, a process known as solution annealing, which enhances the hardness of the material.
