Alloy 20 is a nickel-iron-chromium based, austenitic alloy with excellent corrosion resistance in chemical environments containing sulfuric acid and many other aggressive media. This alloy is stabilized with niobium to resist intergranular corrosion. Alloy 20 may provide potential cost savings when carefully compared to higher nickel-based alloys, while out performing standard stainless steels.
Bend pipe is a common pipe connection element, widely used in chemical industry, petroleum, natural gas, shipbuilding and other industries. It realizes the turn of the pipeline in the horizontal or vertical direction through the shape of the curve, making the pipeline layout more flexible and reasonable. The process of manufacturing stainless steel elbow is very important, which is directly related to its quality and reliability.
