ASTM A182 Duplex Stainless Steel Flanges with advantages in piping applications
Duplex stainless is a mixed microstructure of austenitic and ferrite (50/50) which has improved strength over ferritic and austenitic steel grades with similar corrosion resistance qualities.
The excellent corrosion resistance is said to be the ASTM A182, F51. They are made from the best quality raw material and they are also packed in the wooden cases so that there are no damages being found. S31803 Duplex Fittings which provides a wide variety of outstanding corrosion resistance, which prevents corrosion in sea water and other environmental chlorides at a temperature of filling and over 50 degrees of calcium. ASME SA 182 GR.F51 Duplex Stainless Steel has higher strength than standard stainless steels, higher thermal conductivity than austenitic stainless steels, and higher corrosion resistance than SS 316 in a wide variety of corrosive chemicals including sulphuric, phosphoric and nitric acids.
