ASME SA516 Gr.70N Carbon Steel Tubesheet, Pressure Vessel Plate For Heat Exchangers
ASME SA516 Gr.70N carbon steel tubesheet is a versatile tubesheet plate which is suitable to low and moderate-temperature applications, making it an ideal material for industrial boilers and pressure vessels. This steel plate has good weldability, and excellent notch toughness, making it suitable for boiler plates’ fabrication. ASTM A516 Gr.70N carbon steel tubesheet can be used in the oil, petrochemical and gas industries
What is ASTM A516 Gr.70N?
ASME SA516 Gr.70N carbon steel plate is characterised by excellent weldability and good resistance to brittle cracking. This steel is usually used for manufacturing vessels for pressurised gas, pressure vessels, parts for steam boilers, pressure piping, etc.
What is the difference between ASME SA516 Gr.70 and Gr.70N gardes?
ASME SA516 Gr.70 and Gr.70N are pressure vessel grades which are differentiated based on some certain features.
ASME SA516 Gr.70N is a steel in a normalized condition. The SA516 Gr.70 is not subjected to the normalizing process.
The normalized SA516 Gr.70N possesses superior ductility and toughness over the SA516 Gr.70 Material.
