High Resistance ASTM A240 TP904L 1.4539 N08904 Stainless Steel Plate
High Resistance ASTM A240 TP904L 1.4539 N08904 Stainless Steel Plate
YUHONG manufactures plates using the finest quality of raw materials that are selected by our experts as per the global material standards. Our fabricated plates offer exceptional resistivity against corrosion a well as oxidation.
We have all the modern machinery and technology in our manufacturing house that helps in fabricating more ductile and stable Stainless Steel 904L Plates.
Grade 904L stainless steels have excellent resistance to warm seawater and chloride attack. The high resistance of grade 904L against stress corrosion cracking is due to the presence of high amounts of nickel in its composition. Moreover, the addition of copper to these grades develops resistance to sulphuric acid and other reducing agents in both aggressive and mild conditions.
The corrosion resistance of grade 904L is intermediate between super austenitic grades, with 6% molybdenum content, and standard 316L austenitic grades. Grade 904L is less resistant to nitric acid than grades 304L and 310L, which are free of molybdenum. This steel grade needs to be solution treated following cold working, to achieve maximum stress corrosion cracking resistance under critical environments.
