ASTM A210/ASME SA210 Grade C High Pressure Boiler Steel Tubes
1. Product Description: ASTM A210/ASME SA210 Grade C High Pressure Boiler Steel Tubes are designed for use in high-pressure boiler systems and other thermal applications. These tubes are manufactured from carbon steel and are seamless, providing uniform wall thickness and excellent mechanical properties. The Grade C specification indicates a balance of strength and ductility, making these tubes suitable for applications that demand both high pressure resistance and the ability to withstand thermal cycling.
