Duplex Steel UNS S31254 Ring Type Joint Flanges is generally supplied in the annealed condition giving yield strengths in excess of 44 KSI (300 Mpa). Flanges are components designed to possess unique pressure classes. A pressure class in a flange can be determined as the maximum allowable pressure a flange can withstand when there is a gradual surge of temperature across the system. Flange pressure is characterized by different standards set by different unions. A Class 300 ASTM A182 UNS S31254 flange is not the least but also not the strongest flange. These 254 SMO Flanges are designed to have optimum pressure resistance up to 570psi in temperatures of 600 degrees F. As there is a gradual increase in the temperature, the pressure tolerance in the flange slowly recedes. A 6Mo ring type joint flange is a super austenitic grade of stainless steel that is made up of superior concentrations of molybdenum and nitrogen.
