ASTM A240  UNS S31803 Plates consist of equal ratios of ferrite and austenitic metals. These plates are highly made of excellent quality material and advanced technology. UNS S31803 plates are also a combination of strength ductility and malleability, and the grade combines great mechanical stability and elasticity. Duplex S31803 Plate is being used in various types of industries for a variety of purposes. 

ASME SA240 UNS S31803 grade is a duplex grade with a combination of ferrite and austenitic microstructure which provides great protection from various chemical and physical resistance. The chemical composition of this grade improves its resistance to pitting, forging, and welding. The grade consists moreover 40-50% of ferrite grade that provides excellent exposure at hot and cold temperatures. The grade offers high resistance from various corrosion, crevice corrosion, and stress-cracking procedures. ASME SA240 Gr S31803 Plates are one of the most highly demanded plates in the industry today. 

Chemical Composition: 

The grade Duplex UNS S31803 Plate is made from high-quality materials and extremely ductile elements. The mixture includes high amounts of chromium, nickel, and manganese, whereas the grade includes elements like phosphorus, sulfur, and silicon to provide stability and efficiency to the grade. 

These materials are known for providing great welding and pitting properties to the grade. It is also seen that these elements also provide extra resistance reduction, erosion, and rusting.
