We are involved in manufacturing, supplier of 904L Products in India. These are available in various types, forms, lengths and sizes to meet the diverse requirements of the customers. These are made by using superior quality stainless steel and available in average of the smaller and larger pipe diameter. Furthermore, these 904L Products are checked under various quality parameters to ensure flawless nature. 904L is a high-alloy austenitic stainless steel with low carbon content. The grade is intended for use under severe corrosive conditions. It has been application proved over many years and was originally developed to resist corrosion in dilute sulfuric acid. It is standardized and approved for pressure vessel use in several countries. Structurally, 904L is fully austenitic and is less sensitive to precipitation ferrite and sigma phases than conventional austenitic grades with high molybdenum content. Characteristically, due to the combination of relatively high contents of chromium, nickel, molybdenum and copper 904L has good resistance to general corrosion, particularly in sulfuric and phosphoric conditions.
Alloy 904L (UNS N08904) is a super austenitic stainless steel designed for corrosion and pitting resistance in a wide range of process environments. It is used extensively in the chemical process industry including the production of phosphate-based fertilizers.
The corrosion resistance of 904L is equivalent to most super duplex stainless steels (SDSS) across a wide range of applications. … At low temperatures, 904L will retain good impact toughness, and it is not at risk of forming deleterious intermetallic phases at higher temperatures.
