ASTM A213 T11 Heavy Wall cold drawing seamless Boiler tube
T11 material detail was Seamless Cold-Drawn Intermediate Alloy-Steel Heat-Exchanger and Condenser Tubes.
T11 Alloy Steel Tube (SA213 T11, Chrome-Moly) is a consistent ferritic Alloy Steel Tube for high-temperature administration. These T11 materials including SA213 T11 Seamless Tube and Alloy Steel T11 Tube are reasonable for high-temperature application, for example, twisting, flanging, and comparable framing activities, and for combination welding in the power business and petro-substance plants.
SA213 T11 Alloy Steel Tubing is otherwise called ASTM A213 T11 chrome-moly tube in view of the compound cosmetics of Molybdenum (Mo) and Chromium (Cr). Molybdenum keeps up the quality of ASME SA213 T11 square cylinder just as far as possible, protection from wear, sway characteristics, and hardenability. Moly is the best single added substance that upgrades the high temperature creeps quality of SA213 T11 Tubes Suppliers.
