Products Description
SUS317 stainless steel contains high chromium, nickel and molybdenum elements, which make it have excellent corrosion resistance and oxidation resistance, especially in strong oxidizing media. In addition, SUS317 also has good high temperature strength and toughness, and can maintain stable performance at high temperatures. Therefore, it is widely used in chemical, petroleum, offshore engineering, pharmaceutical and other fields.
The SUS317L stainless steel is a low-carbon version of the SUS317, which improves its welding performance and corrosion resistance by reducing its carbon content. Compared with SUS317, SUS317L has better corrosion resistance, especially in the welding and heat treatment process is more resistant to sensitization. Therefore, it is more suitable for welding or high temperature treatment occasions.
