Take the test coupons from the center of the plate width. Historical Version s – view previous versions of standard. It is generally caused by strain induced in the thickness direction resulting from shrinkage of the weld deposit and by the restraint imposed by the components that comprise the weldment.
The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. The tests shall be representative of the plate in its?
This documents may be applied as a supplement to all product standards for flat products and sections of fully killed steel, except stainless steel.

In all cases, the minimum length of the reduced section must be as speci? Reduction of Area Requirements S3. The more common processes, used singly or in combination, are: Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. This scatter of test results is due in part to the inherent variability of the distribution of the nonmetallic inclusions discussed in X1.

A series of two or more Type F specimens may be used to cover the full thickness of the plate. A number in parentheses indicates the year of last reapproval. The tension testing method shall provide a measure of the resistance of a steel plate to lamellar tearing.

The length of the reduced section Aas shown in Fig. On the other hand, a reduction in the magnitude and concentration of these inclusions to a low level tends to preclude any easy fracture path along the low ductility inclusions and the steel exhibits improved ductility in a throughthickness direction.
Within the text, the SI units are shown in brackets. The number of tests and test positions have not been established that would provide a good estimate of both the mean and the variability of through-thickness tensile reduction of values of a plate.
The number of tests required will depend upon axtm thickness of the plate being tested and the reduced section length selected. The tearing may remain completely subsurface or appear at plate edges or at weld toes. Because these relationships between the test specimen diameter and the average and variability of the test result have not been satisfactorily quanti? Combining values from the two systems may result in nonconformance with the specification. Resources Digital Transformation may be defined in a number of different a7770 by analysts or enterprise software vendors.
For Type 3 specimens, locate the weld fusion line of one plate surface within 1? To provide a high resistance to lamellar tearing may require the use of special steel-making processes that can reduce the oxygen and sulfur contents in the steel to very low levels.
Two tests shall be required from each quenchedand-tempered plate. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.
