ASTM A213 T5 is a chromium-molybdenum alloy seamless steel tube under ASTM standards, with chromium (Cr) content of 4.00-6.00% and molybdenum (Mo) content of 0.45-0.65%. This special alloy composition endows the material with unique high-temperature performance. In operating environments above 600°C, T5 steel maintains stable mechanical properties, with tensile strength exceeding 415 MPa and yield strength surpassing 205 MPa. Compared to ordinary carbon steel, its creep resistance improves by approximately 3 times, demonstrating particularly outstanding corrosion resistance in sulfur-containing media.
This material complies with ASTM A213/A213M standard, which strictly regulates dimensional tolerances, mechanical properties, heat treatment processes, etc. The Chinese equivalent standard is GB 5310-2017's 15CrMoG steel grade, though with slight differences in molybdenum content control. It is noteworthy that ASTM A213 T5 tubes must undergo normalizing and tempering heat treatment, with the metallographic structure requiring uniform ferrite-pearlite and grain size controlled within grade 5-8 range.
