ASTM A333 GR.6 Pipes Charpy V-Notch Impact Test
Toughness, or ductility, is the ability of a material to resist impact, to withstand repeated reversals of stress, or to absorb energy when stressed beyond the elastic limit. Steel is normally considered to be a ductile material, however, it may shatter just as glass at certain low temperatures. The critical ductile-to-brittle transition temperature (CDBTT) for any steel is the temperature above which the steel behaves in a predominantly ductile manner and below which it behaves in a predominantly brittle manner. The low alloy steel pipe of ASTM A333 Gr.6 with a low CDBTT can be used at temperatures down to -45°C [-50°F]. It is important to verify that the pipe materials are impact tested and exhibit a sufficient high Charpy toughness.
The Charpy V-notch impact test shall be conducted at -45°C [-50°F] with three testing specimens in the size of 10 mm x 10 mm x 55 mm. The minimum average energy absorbed for three specimens shall be 18 J [13 ft*lbf], and the minimum energy absorbed for each specimen is 14 J [10 ft*lbf]. The actual tests have been done to three specimens which were taken from ASTM A333 Gr.6 seamless pipes produced by BAOSTEEL. The results listed in the table below indicate that the steel exhibits superior impact toughness, which is at least 20 times higher than the standard value.
