904L Material has carbon, manganese, silicon, phosphorus, sulfur, chromium, molybdenum, nickel and copper. As a leading supplier of SS 904L Flange. The Class 150 ANSI SS 904L Flanges are a lower class of many pressure classes. There are pressure classes up to PN64. The pressure classes are determined by the wall thickness and the nominal bore size of the flanges. There are different specifications such as the ASTM B649 UNS N08904 Flange. Some standards maintain the nominal bore sizes of SS 904L Flange. The ANSI B16.5 SS 904L Blind Flange falls under the B16.5 standard and the nominal bore sizes range from ½ inches to 48 inches.
Stainless Steel 904L Flanges come under ASTM B649 specification with various standards according to ANSI, ASME, DIN, and EN standards. The sizes of SS 904L Flanges range from ½ inches to 48 inches and the pressure classes vary. ASME SA182 SS 904L WNRF Flanges are welded neck-raised face flanges. SS 904L Flange has welded necks and raised faces, both for added strength and SS 904L Flange can range in pressure classes from 150 through 2500 and PN6 through PN64.

FAQs
1. What is the 904L material grade?
This grade is written as 1.4539 or X1NiCrMoCu25-20-5 according to EN norm and it is written as UNS S08904 according to UNS norm. 904L stainless grade contains very high levels of nickel, molybdenum, chromium, and combinations of all these elements making this stainless steel grade very resistant to corrosion resistance.
2. Where is 904L steel used?
It has applications in piping systems, pollution control equipment, heat exchangers, and bleaching systems.
3. What is the chemical compatibility of 904L?
The addition of copper to this grade gives it corrosion-resistant properties superior to the conventional chrome nickel stainless steels, in particular to sulphuric, phosphoric, and acetic acids. However, there is limited use of hydrochloric acids.
