Product Introduction

High Quality Duplex UNS S31803

Specifically, the chemical composition and organizational structure of UNS S31803 stainless steel give it high strength and hardness, as well as good plasticity and toughness. After solid solution treatment, it has a mixed structure of austenite and ferrite. After specific heat treatment, higher strength and better corrosion resistance can be obtained. This kind of stainless steel has good resistance to corrosive media such as chloride ions and oxidants, and can be used in various harsh environments, such as marine environment, chemical industry, food processing and other fields.

In addition, the welding performance of UNS S31803 stainless steel is also very good, and the welded joints have good corrosion resistance and mechanical properties. This stainless steel also has good processing properties and can be obtained in the desired shape and size through various processing methods.
