ASTM A213 T5B
ASTM A213 T5B is a steel grade of ASTM A213 Standard Specification
ASTM A213 T5B for Seamless Ferritic and Austenitic Alloy-Steel Boiler, Super heater, Heat-Exchanger Tubes.
ASTM A213/A213M -17 Standard Specification for Seamless Ferritic and Austenitic Alloy-Steel Boiler, Superheater, and Heat-Exchanger Tubes.
ASTM A213 T5B Alloy Seamless Steel Pipe Dimensional Range & Specification
Length：6000mm、12000m or specified length as required.
ASTM A213 T5B Alloy Seamless Steel Pipe Chemical Composition(%)
An analysis of either one billet or one tube shall be made from each heat. The chemical composition thus deter- mined shall conform to the requirements specified.
ASTM A213 T5B Alloy Seamless Steel Pipe Mechanical & Physical Properties
Brinell, Vickers, or Rockwell hardness tests shall be made on specimens from two tubes from each lot.
Flattening Text—One flattening test shall be made on specimens from each end of one finished tube, not the one used for the flaring test, from each lot.
Flaring Text—One flaring test shall be made on speci- mens from each end of one finished tube, not the one used for the flattening test, from each lot.
Mechanical property requirements do not apply to tubing smaller than 1⁄8 in. [3.2 mm] in inside diameter or thinner than 0.015 in. [0.4 mm] in thickness.
Hydrostatic or Nondestructive Electric Test
Each tube shall be subjected to the nondestructive electric test or the hydrostatic test. The type of test to be used shall be at the option of the manufacturer, unless otherwise specified in the purchase order.
Tubes, when inserted in a boiler or tube sheet, shall stand expanding and beading without showing cracks or flaws. Superheater tubes when properly manipulated shall stand all forging, welding, and bending operations necessary for appli- cation without developing defects.
