- High Temperature service Alloy Steel tube are known as Chrome Moly pipe. ASTM A213, A209 specification covers Alloy Steel Seamless tube for high temperature service. These tube are suitable for bending and similar forming operations, and for fusion welding at high temperatures. High Temperature Alloy Steel tube are also considered as low Alloy Chrome Moly grades. ASTM/ASME A/SA213 Gr. T2, T11, T12, T22, T91, T92 ASTM/ASME A/SA335 Gr. P1, P2, P5, P11, P12, P22 ASTM/ASME A/SA209 T1, T1a, T1b ASTM A213 tubing has been widely used in high temperature services especially for the boiler and superheater. Tube material could be in alloy steel and stainless steel, and manufactured in seamless of hot rolled or cold drawn. Common grades are T9, T11, T12, T21, T22, T91 and stainless grades in TP304 or TP316.
