SS904 and 904L
Thread Content
I’m facing a problem: a client who needs a stirred-tank reactor at atmospheric pressure has requested that the material used be SS904 or 904L. I need to prepare a budget, and I was wondering if anyone knows the price – roughly how much does it cost per ton?
It should be available from manufacturers online; 904L doesn’t seem to be cheap – I heard that it costs over 400,000 yuan per ton. Steel prices are fluctuating greatly these days, so go and consult the manufacturers directly.

The price of 904L sheets is slightly more than twice that of 316L; it is currently around 70,000–90,000 yuan per ton. The price of pipes is 1.2 times that of sheets. I use it on sulfuric acid dilution pipelines and dilute sulfuric acid storage tanks.
What are the corrosion resistance data of 904L against dilute sulfuric acid? Do you have any materials? Can you send them via email? QQ348098628
Currently, there are no corrosion resistance data available in this regard. Foreign literature is difficult to find, as the company has blocked access to it. The storage tank is very small, with a capacity of 6 cubic meters; it is used for testing 904L material. The pipes are made of 904L instead of ABS. Since the project has not yet been commissioned, there are no data available for now. I will provide feedback after the project is tested next year.
I have the materials; see the article I summarized in the Corrosion section, “The Most Comprehensive List Ever! \"Equal corrosion diagrams and corrosion rates of various materials in sulfuric acid\", which contains detailed equal corrosion diagrams for 904L
