904L is a super austenitic alloy with higher nickel and molybdenum content, providing significantly better resistance to dilute sulfuric acid and chloride-induced pitting than 316L.
Yes, it is ideal for temperatures below 750°F. However, it is important to note that the material can become brittle if exposed to temperatures exceeding this threshold.
No, 904L remains non-magnetic under all standard conditions, making it suitable for specialized electronic and precision industrial applications.
It is widely used in wastewater treatment, biofuel production, marine fittings, liquid filtration, and chemical processing plants dealing with aggressive acids.
It is easily welded; however, it requires higher cutting forces for cutting and forming compared to T-316L due to its superior strength.
While excellent for most acids, 904L is generally less resistant to nitric acid compared to T-304L, which does not contain molybdenum.
