904l SS blind flanges raised an austenitic steel which is use for different conditions these are well known for their properties. These are widely used for closing the tail of pipe of a pressure vessels as they are design to control the pressure in a high pressure area.SS 904l plate flanges are super austenitic alloy which is moderate to high resistance in a wide range of process environment. These plates are generally used in heat exchangers, tanks and valves. We are having the best quality production of SS 904l in India.

904l is a material which contain very low carbon. These steel is designed for the harsh corrosion. 904l has been manufactured in many countries now and they have improved the standards. It has excellent quality of resistance. The highest temperature hitting up to 1180 calicos and lowest temperature stop forging not less than 990 Celsius.

UNS N08904 SS socked weld flanges are known for excellent performance. These steel meet the requirements of many industries and is an ideal for use at a high pressure and varied cold or high temperature
