About Duplex Steel S31803 Bars
UNS S31803, also called Duplex Steel S31803 bars, is a type of duplex stainless steel well-known for its strength and resistance to corrosion. These bars have a microstructure divided almost 50/50 between austenite and ferrite and offer high performance in harsh conditions. S31803 is used in many industries because of its excellent properties, so it is suitable for applications that must be both strong and long-lasting.
