*   Brinell hardness (HB) readings taken from the standard test locations on the plate surface after the decarburization layer is removed. These ranges of HB convert to 27-34 and 23-34 Rockwell "C".   Bethlehem uses HB measurements as its official test.

** May also be specified as Clean-Cut� where improved machinability is desired.

FGP = Fine Grain Practice F/L = Fineline� Double-O-Five or better available
N&T = Normalized and Tempered Q&T = Water Quenched and Tempered
This mold is made possible by Bethlehem's Fineline� process, an advanced technique for sulfur removal.
