FAQ’s About Stainless Steel 904L Pipe Fittings
Stainless Steel 904L is a low carbon, high-alloy austenitic stainless steel. It contains high levels of chromium, nickel, molybdenum, and copper. This composition provides excellent resistance to corrosion in aggressive environments.
Yes, 904L offers superior corrosion resistance compared to 316/316L, especially in chloride and acidic conditions. It performs better in harsh chemical environments. However, it is more expensive and used for critical applications.
904L is equivalent to UNS N08904 and EN 1.4539 grades. It is also comparable to other high-alloy austenitic stainless steels. These equivalents ensure similar corrosion resistance and performance.
The typical hardness of Stainless Steel 904L is around Brinell 150–190 HB. It is relatively soft compared to other stainless steels. This makes it easy to form and weld while maintaining good strength.
The typical hardness of Stainless Steel 904L is around Brinell 150–190 HB. It is relatively soft compared to other stainless steels. This makes it easy to form and weld while maintaining good strength.
