High Strength & Pressure Resistance:
Combining the advantages of ferritic and austenitic stainless steels, UNS31803 seamless steel pipe has high strength and superior pressure resistance for high-pressure, high-strength application scenarios.
Excellent corrosion resistance:
UNS31803 material has excellent corrosion resistance, especially in chloride-containing environments with superior resistance to stress corrosion cracking. It can effectively resist corrosive media such as seawater and acidic chemicals to extend equipment life.
Good toughness and ductility:
The duplex structure makes UNS31803 seamless steel pipe maintain good toughness and ductility at both low and high temperatures, and is not easy to be embrittled, which ensures stable performance under various temperature conditions.
Excellent welding performance:
UNS31803 material has good welding performance, can be welded without preheating and post-heat treatment, and the performance change after welding is small, to ensure the quality and reliability of welded joints.
Wear resistance and fatigue resistance:
UNS31803 seamless steel pipe has high wear resistance and fatigue resistance, which can maintain stable performance under long-term loads, and is suitable for equipment and systems that need to operate for a long time.
Packaging Details:Woven bags or according to customer requirements
Port:SHANGHAI/NINGBO
