What is ASTM/ASME A/SA213 Grade T5 boiler tube?

ASTM/ASME A/SA 213 Grade T5 is a type of seamless ferritic alloy steel boiler tube. It is designed for use in high-temperature and high-pressure service, particularly in the construction of boilers and heat exchangers. Grade T5 is commonly used in the power generation, petrochemical, and oil and gas industries.

The chemical composition of ASTM/ASME A/SA213 Grade T5 boiler tube is as follows:

Carbon (C): 0.15% maximum

Manganese (Mn): 0.30-0.60%

Phosphorus (P): 0.025% maximum

Sulfur (S): 0.025% maximum

Silicon (Si): 0.50% maximum

Chromium (Cr): 4.00-6.00%

Molybdenum (Mo): 0.45-0.65%

Additionally, Grade T5 may contain small amounts of other elements such as nickel (Ni), vanadium (V), and aluminum (Al), among others.

The mechanical properties of ASTM/ASME A/SA213 Grade T5 boiler tube are as follows:

Tensile strength: 415 MPa (60,200 psi) minimum

Yield strength: 205 MPa (29,700 psi) minimum

Elongation: 30% minimum

Hardness: Brinell hardness of 163 maximum, Rockwell hardness of B85 maximum

Overall, ASTM/ASME A/SA 213 Grade T5 boiler tube has excellent high-temperature strength and resistance to corrosion and oxidation. It is a popular choice for use in high-temperature and high-pressure applications where reliability and durability are essential.
