1. Super duplex stainless steel has higher strength and better corrosion resistance. This is due to the difference in its chemical composition and microstructure. Super duplex stainless steel contains more chromium, nickel, aluminum, and other elements, which can enhance the corrosion resistance of the material. At the same time, its microstructure is also formed by the interaction of austenite and ferrite, which gives it higher strength and better plasticity.

2. Super duplex stainless steel also has better welding performance. Due to the special properties of its chemical composition and microstructure, it can be welded by conventional welding methods without special treatment. This makes super duplex stainless steel more convenient in manufacturing and processing

Super duplex stainless steel also has some disadvantages. First, its price is usually higher than ordinary stainless steel. This is due to the complexity of its chemical composition and manufacturing process. Secondly, due to its high strength and hardness, super duplex stainless steel is more difficult to process and form. This may lead to an increase in production costs.
