Two tests shall be required from each quenchedand-tempered plate. For example, those nonmetallic inclusions that form during the solidi? Close this window and log in. The joining method used shall be one which results in a minimal heat-affected zone in the portion of the plate to be tested.

Within the text, the SI units are shown in brackets. This minimum value may be from 1. A minimum slenderness ratio of 2 was selected for the standard Type 2 specimen to allow a 0.

To improve the through-thickness ductility and thus the resistance of the steel to lamellar tearing, it is necessary to reduce the level of the nonmetallic inclusions. Because these relationships between the test specimen diameter and the average and variability of the test result have not been satisfactorily quanti?

It is generally accepted that there is a diameter effect on reduction-of-area values such that a smaller diameter specimen generally yields a higher average reduction in area value. Location of Test Coupons S5.

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. This abstract is a brief summary of the referenced standard.

It does not refer to the condition of the plate. The principal purpose of the testing is to provide a measure of the resistance of a steel plate to lamellar tearing. Current edition approved May 10, Some of these factors are discussed in X2. A Test Methods and De?
