Question: Is it possible to use a 304 stainless steel container for a 20% urea solution, heating it to 90 degrees with no pressure? What kind of material is needed if it won’t work? What material is the most cost-effective choice? Thank you

Under such conditions, 304 can meet the requirements.

In normal applications, 304 is sufficient, and there are existing examples of its use; however, if you are a designer, it’s better to be cautious.

Regarding the design, what materials are needed? Please explain upstairs

2507 duplex stainless steel, superior to 304

Urea-grade 316L; if you prefer to be cautious, use this one. Generally, if the heating method does not cause local high temperatures that would lead to the decomposition of urea and the formation of corrosive substances, then 304 or 304L will suffice
