Hi,

Simple question, trying to find the ASTM testing standard to machine/ produce a test coupon for tensile testing. Does anyone know the test number.

RE: preping tensile sample

ASTM E 8M Standard Test Methods for Tension Testing of Metallic Materials [Metric]

ASTM E 8 Standard Test Methods for Tension Testing of Metallic Materials

RE: preping tensile sample

One little item to remember--round tensile specimens need to taper from the transition radius to the center of the gauge area. I have never seen this denoted on any standard drawings for tensile specimens.

RE: preping tensile sample

There is also a slight (0.0005"?) reduction in width right at the center of the gauge length when cutting flat samples using a Tensilkut machine.

thanks guys, what i am looking at is welding a 1.5" nitronic rod and doing a pull test on the weld. making sure that the weld will meet what i need. This is still the valid test procedure correct.

RE: preping tensile sample

from what i remember the part had to be machined to 50 mm or so for length wise to do pull tests. But as of right now i think yes we would be machining the specimen.

RE: preping tensile sample

there is definately a different spec for tensile testing of welds. E8 is for raw material, bar, sheet, tube, etc....

If you dont have to test to a spec, then you could design a test to measure what you are trying to find out. If you have to test to a specification, then you have to test to a specification.
