Temperature Range of ASTM A210 GRC Pipe
The temperature range of ASTM A210 GRC pipe (20G steel) is as follows:
Operating Temperature: SA-210C (20G) steel has good strength and oxidation resistance up to 450°C, but pearlitic spheroidisation and graphitization will occur during long term operation at temperatures ranging from 470°C ~ 480°C.
Recommended Use Temperature: Since graphitising will occur in carbon steel during long term operation above 450°C, it is desirable to limit the maximum long term use temperature of tubes as a heating surface to below 450°C.
In summary, ASTM A210 GRC tubes are suitable for use in environments where temperatures do not exceed 450°C. Prolonged operation at higher temperatures may result in degradation of material properties.
