Stainless Steel - Urea-Grade Austenitic Seamless Tubes

These tubes are primarily used in the core components of synthetic ammonia and urea industries. The raw materials are obtained through ESR, and during production, apart from strict control over cleanliness, particular emphasis is placed on the heat treatment process, with domestic products currently largely reliant on imports. Our company produces urea-grade stainless steels including Super- pure 316Lmod and S31050, both of which belong to the category of super-pure stainless steels. They are specifically designed to address the issue of selective corrosion that readily occurs in ferritic steels under ammonia environments during urea synthesis.The manufacturing process of these products adheres rigorously to standardized procedures, ensuring excellent corrosion resistance as verified by the Hughes Test. Furthermore, this product plays a vital role in the hydrogen energy industry.
