Possible Alternative Grades of ASTM A240 TP 904L Stainless Steel Plates and Sheets The suitable alternatives to 904L stainless steels are tabulated below:
Possible alternative grades to grade 904L stainless steels
| Grade | Reasons for choosing grade 904L |
| 316L | A lower cost alternative, but with much lower corrosion resistance. |
| 6Mo | A higher resistance to pitting and crevice corrosion is needed. |
| 2205 | A very similar corrosion resistance, with the 2205 having higher mechanical strength, and at a lower cost to 904L. (2205 not suitable for temperatures above 300°C.) |
| Super duplex | Higher corrosion resistance is needed, together with a higher strength than 904L. |
Corrosion Resistance of ASTM A240 TP 904L Stainless Steel Plates and Sheets 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.
Heat Resistance of ASTM A240 TP 904L Stainless Steel Plates and Sheets Grade 904L stainless steels offer good oxidation resistance. However, the structural stability of this grade collapses at high temperatures, particularly above 400°C.
Heat Treatment of ASTM A240 TP 904L Stainless Steel Plates and Sheets Grade 904L stainless steels can be solution heat-treated at 1090 to 1175°C, following by rapid cooling. Thermal treatment is suitable for hardening these grades.
ASTM A240 TP 904L Stainless Steel Plates and Sheets Packing
ASTM A240 TP 904L Stainless Steel Plates and Sheetsis sleeved into plastic bag individually, pieces wrapped with water-proof material, bundled with nylon rope. Clear labels are tagged on the outside of the package for easy identification of the quantity and product I.D. Great care is taken during operation and transportation. SS 904L Stainless Steel Plate packing will be according to international standard in bundles strapped by strips then into containers to avoid any damage.
