TPI Approved Alloy Steel ASTM A213 T5 Seamless Tube For Boiler
T5 Alloy Steel Tube (SA213 T5， Chorme-Moly) is a seamless ferritic Alloy Steel Tube for high temperature service. These T5 material including Alloy Steel T5 Tube and SA213 T5 Seamless Tube are suitable for high temperature application such as bending， flanging (vanstoning)， and similar forming operations， and for fusion welding in the power industry and petro-chemical plants.
SA213 T5 Alloy Steel Tubing is also known as ASTM A213 T5 chrome moly tube because of the chemical makeup of Molybdenum (Mo) and Chromium (Cr). Molybdenum maintain the strength of SA213 T5 Boiler Tube as well as the elastic limit， resistance to wear， impact qualities， and hardenability. Moly is the most effective single additive that enhance high temperature creep strength of ASTM A213 T5 Tubes.
