Tensile Test of Class B Armor Steel with Special Reference to Size Effects

Abstract

It is believed appreciation of the attached report will be improved by the following amplifying comments. As described in previous reports, the block of heavy Class B armor from which samples are being taken for this study is a fairly coarse grained Ni-Cr steel plate formed from a 200 ton open hearth heat poured into one in ingot and reduced about 3- 1/2 to 1 with forging under a press. Under such circumstances a close agreement of reduction of area values for small tensile bars taken from central regions of the plate is not expected.
