Difference between SA209 and A213

SA209 Standard

Standard name: ASME SA-209/SA-209M
Material Type: Mainly used in high pressure boilers for heating surfaces, economisers, header boxes, superheaters, reheaters, etc.
Characteristics: SA-209 standard covers a series of steel grades of seamless steel tubes used in high pressure boilers, such as T1, T1a, T1b, etc. These tubes are widely used in high pressure boilers in modern industry due to their excellent high temperature resistance and mechanical properties.

A213 Standard

Standard Name: ASTM A213/ASME SA-213
Material Type: For seamless iron element and austenitic steel tubes of minimum wall thickness for boilers and superheaters and austenitic steel tubes for heat exchangers.
Features: The A213 standard includes several types of tubes, such as T11, T12, T22, etc. These tubes are suitable for applications in high temperature environments, such as boilers and superheaters, due to their excellent high temperature properties and mechanical properties.

Comparison of application areas

SA209: Widely used in key components of high-pressure boilers due to its high strength and good resistance to high temperatures.
A213: seamless steel tubes suitable for boilers and superheaters, including iron element and austenitic tubes, as well as austenitic tubes for heat exchangers, emphasising their suitability for use in high temperature environments.
