Manufacturing & Testing of ASTM A213 T12 Seamless Alloy Pipe
T12 tubes are produced using a seamless process and can be hot-finished or cold-finished. Heat treatment is performed separately, with ferritic alloy and stainless steels undergoing reheating. Austenitic stainless steel tubes are delivered in a heat-treated condition. Alternatively, hot-formed tubes can be rapidly cooled by quenching in water or other methods.
To ensure quality and performance, ASTM A213 T12 tubes undergo rigorous testing, including:
Tension Test
Hardness Test
Flattening & Flaring Testt
Non-Destructive Electric or Hydrostatic Test
Chemical Composition(%) for ASTM A213 T12 Low Alloy Steel
ASTM A213 T12 tubes are made from low alloy steel with a chemical composition that typically includes chromium (Cr) and molybdenum (Mo). These elements enhance the material's strength, hardness, and resistance to high-temperature environments.
