temperatures ranging from -200F to 6000F. Two plate
thicknesses, eight material heats, and both base and weld metal
were investigated.
Although 304L and 316L stainless steel materials have
been studied for many years and by numerous investigators [2-
5], relatively little recent, typical data reflecting current
commercial chemical compositions and dual-stamping is
readily available to practitioners. Even less data expressed as
true stress-strain relationships to failure can be found in the
literature. The purpose of this paper is to present some typical
results of quasi-static tensile testing of 304L and 316L stainless
steels in order to add to the existing data pool for these
materials and make the data more readily available to other
researchers, engineers, and interested parties. Typical stress-
strain values are often of interest for failure analyses and
integrity evaluations associated with low probability, extreme
loading conditions. A comparison to ASME Code minimums
is also made.
MATERIALS AND SPECIMEN PREPARATION
Two commercial, readily available, dual-stamped stainless-
steel alloys, 304L and 316L, were tested in this study. The
alloys were procured from various manufacturers as 48-inch by
120-inch plate material satisfying the ASME SA-240 standard
specification [6]. Both alloys were purchased from four
different heats and in two different thicknesses, -inch and-1 2
inch. Plate thickness was a functional requirement for dynamic
strain rate specimens not discussed in this paper. For the
purposes of this reporting, material thickness effects were
assumed negligible. The as-received plate material was hot
rolled, annealed, and pickled (HRAP finish). The plate's
chemical composition and minimum room temperature
mechanical properties as reported by the manufactures are
listed in Table 1.
Base metal test specimen blanks were cut from the as-
received plate with the longitudinal axis of the specimens
parallel to the rolling direction of the plate. Standard, round
0.350 inch diameter test specimens were machined from the 12-
inch thick plate blanks to the dimensions specified in ASTMA370-03a as shown in Fig. 1.
Specimen blanks from the -inch thick plate were also
machined into round 0.160-inch diameter specimens
proportional in size to the standard specimen. The ends of the
specimens outside of the gage length were threaded to match
the holders on the tensile test machine. Specimens were not
further treated following machining.t ..255 S Detai

The weld test specimen blanks were prepared by first
welding two pieces of longitudinally cut as-received plate
material together and then cutting the specimen blanks centered
on the axis of the weld. Using a gas tungsten arc welding
process, a full penetration groove weld was completed with
welding from both sides. The weld was designed to result in a
region of welded material sufficient to produce a machined test
specimen of full weld material in the gage region. All welds
were radiographed prior to acceptance. Welded test specimens
were machined to the same geometry and dimensions as the
base metal specimens.
TEST PROCEDURE
Conventional quasi-static tensile tests were performed at
room temperature (z 700F), -200F, 3000F, and 6000F using an0to2 I
