Tension Testing of Metallic Materials (ASTM E8)
ASTM E 8 describes tension testing methods to determine yield strength, yield point elongation, tensile strength, elongation and reduction of area of metal products. It applies to metallic materials in any form, including: sheet, plate, wire, rod, bar, pipe and tube. For each of these specimen

Powder metal's most innovative designs
. The 316 stainless-steel latch attaches to a door handle on a medical infusion pump. It has a density of 6.7 gm/cm3, an 11.5% elongation, and ultimate tensile and yield strengths of 65 and 42 kpsi, respectively. Secondary operations are limited to deburring, tempering, glass-bead finishing
