AISI 316L MOD is is modified 316L, which is the AISI standard grade of the United States. Urea-grade ultra-low carbon stainless steel is a modified 316L, which belongs to austenite-ferrite duplex stainless steel. It is specially used in the urea industry, so it is called urea-grade 316L.
Because of its excellent welding hot crack resistance and intergranular corrosion resistance, it is commonly used as a high-pressure pipeline material for petrochemical urea plants.
Urea-grade stainless steel is a kind of austenitic stainless steel specially used in the urea production process. In the production process of urea, intermediate products such as ammonium carbamate have strong corrosion to stainless steel. Generally, stainless steel, such as 316L, cannot meet its corrosion resistance requirements.
