UNS S21800 Urea Class Stainless Steel


UNS S21800 stainless steel offers corrosion and abrasion resistance at a much lower cost than cobalt and nickel alloys. Its overall corrosion resistance is superior to Type 304 in most media. In UNS S21800, the resistance to chloride pitting is better than Type 316. The yield strength at room temperature is almost twice that of 304 and 316. UNS S21800 has excellent high temperature oxidation resistance and low temperature impact resistance.
