Previous experiments confirmed peak yield strengths
after aging depend on the cooling rate during quenching.
To investigate the effects of steel yield strengths
on the deformability of RC beams, [[theta].
The importance is predicated on this: while HSS has yield strengths
from 210 to 550 MPa and tensile strengths of 270 to 700 MPa, the ultrahigh strength steels (UHSS), which is the extreme end of the AHSS category, have a yield strength
of 550 MPa or more and a tensile strength of 700 MPa or more.
Tensile yield strengths
were 1769 psi for nylon 66 and 1203 psi for nylon 12, or 92% and 63% of virgin PE strength, respectively.
For specimens parallel to the flow direction, the yield strengths
at different melt temperatures were very close and the stress-strain curves after yielding did not show much difference.
They are highly resistant to stress corrosion cracking and higher tensile and yield strengths
than ferritic and austenitic grades and are used in heat exchangers and food pickling plants.
This new domestic source of martensitic stainless steel production tubing will be available in a variety of yield strengths
Lower austempering temperatures produce freer structures that have higher tensile and yield strengths
and superior wear resistance.
Table 1 gives the yield strengths
and yield strains obtained with the L-direction specimens containing a central hole.
What's happening is that there is a comparatively new class of steel, ultra high strength steel, or advanced high strength steel (AHSS), materials with yield strengths
in excess of 550 MPa.
The facility is expected to be in operation by mid-1999 and will produce cut-to-length steel in thicknesses up to 1/2 inch, widths up to 96 inches, and yield strengths
up to 100,000 pounds per square inch.
Tests were performed at 1 mm/min cross-head speed to determine the Young's moduli and at 100 mm/mn cross-head speed (standard ISO 178) to determine the yield strengths
