SS Boiler Tube ASTM A213

Short Description:

High Pressure ASTM A213 TP304H TP321H TP347H 309S 310S Boiler Tubes are those tubes, which have the capacity of handling with high pressure and temperature. We are having a comprehensive range of high pressure boiler tube. Our production unit is using premier quality of raw material in the production of high pressure Boiler Tube. We selected prime raw material,cold drawn, cleaning and smooth surface on OD/ID, Withstand high pressure, no deformation after coldbending, no crack and break after flattening and flaring etc.

    SPECIFICATION
    ASTM A213 TP304H TP321H TP347H 309S 310S Boiler Tubes Main material grade:
    310S Stainless steel is a combination of good strength and corrosion resistance in temperature up to 2100oF (1149℃). Due to its relatively high chromium and nickel content it is superior in most environments to 304 or 309 stainless.
    309S High corrosion-resistant, chromium nickel grade with carbon limited to .08 to reduce carbon precipitation during welding. Maximum Recommended Service Temperature Continuous 1100℃ /Intermittent 980℃
    304H the carbon content is controlled to a range of 0.04-0.08 to provide improved high temperature strength to parts exposed to temperatures above 800°F (427℃)
    321H advantage an excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800 to 1500°F (427℃ to 816°C).
    347H and 347HFG in higher elevated temperature allowable stresses for these stabilized alloys for ASME Boiler and Pressure Vessel Code applications. The 321 and 347 alloys have maximum use temperatures of 1500°F (816°C)Widely used in the following fields: High Pressure Boiler, Boiler tubing , Condenser tubing,
    Main Testing Terms and Procedure:
    • Heat Treatment and Solution Annealing / Bright Annealing
