Product Details

Urea grade stainless steel is a special austenitic stainless steel. The urea grade stainless steel used for urea production mainly consists of 316UG, 00Cr25Ni22Mo2N (2RE69). Urea production is synthesized from carbon dioxide and ammonia at high pressure (140 ~ 250 atmospheres) and 180 ~ 210 ℃ temperature. The intermediate product ammonium carbamate has a strong corrosion to stainless steel, such as 316L stainless steel can not meet its corrosion resistance. The developed special steel bell is called urea grade stainless steel.
