China ASTM A210/A210M - Standard Specification for Seamless Medium-Carbon Steel Boiler and Super-heater Tubes Manufacturer, Manufacturers
Scope  This specification covers seamless medium-carbon steel tubes for boilers, super-heaters, and other high-temperature pressure applications. The standard includes mechanical properties, chemical composition, and testing requirements.
ASTM A210 covers seamless medium-carbon steel boiler and superheater tubes designed for pressure applications and heat transfer.
What are the main differences between Grade A-1 and Grade C?
Grade C offers higher tensile strength (485 MPa min) and yield strength (275 MPa min) compared to Grade A-1, which has 415 MPa tensile and 255 MPa yield strength.
Does ASTM A210 require heat treatment?
Yes, all tubes must be heat-treated. Typical processes include annealing, normalizing, or stress relieving as per the standard.
Are hydrostatic tests mandatory for every tube?
Yes, each tube must undergo either hydrostatic testing or non-destructive electric testing (NDT) to ensure its integrity for pressure use.
What information is required when ordering ASTM A210 tubes?
You must specify the quantity, material grade (A-1 or C), dimensions (OD and wall thickness), length, and any optional testing or certification requirements.
Can these tubes be used for superheaters?
Yes, ASTM A210 is specifically standardized for use in both boiler tubes and superheater tubes in medium-carbon steel.
