SA 213 T5 tubes are seamless ferritic alloy steel tubes, specifically designed for high-temperature applications in industries such as power generation, oil & gas, petrochemicals, and refineries. These tubes are part of the ASME SA213 specification, which covers alloy steel and stainless steel tubes intended for service in boilers, superheaters, and heat exchangers. Known for their strength, thermal stability, and corrosion resistance, SA 213 T5 tubes are an ideal solution for critical pressure systems operating under extreme heat.

Chemical Composition of SA 213 T5 Tubes
Element Composition (%)
Carbon (C) 0.15 max
Manganese (Mn) 0.30 – 0.60
Phosphorus (P) ≤ 0.025
Sulfur (S) ≤ 0.025
Silicon (Si) 0.50 – 1.00
Chromium (Cr) 4.00 – 6.00
Molybdenum (Mo) 0.45 – 0.65
This balanced alloy composition enhances resistance to scaling, thermal stress, and oxidation, making SA 213 T5 suitable for high-performance thermal environments.

Mechanical Properties of SA 213 T5 Tubes
