Jul 10, 2014 · I'm designing a structure which requires high-strength stainless steel bolts. I have spec'd out 1" diameter ASTM A193 B8 Class 2 bolts, with a yield stress of 80 ksi and an ultimate stress of 115 ksi. I'm now trying to spec out nuts to go …

Mar 26, 2010 · During a luminaire pole submittal review I noticed a fabricator had specified the material for a square HSS as ASTM A500 Gr. B. Rather than listing the yield strength as 46ksi, they indicated it as 55ksi on the drawing and used 55ksi as the yield strength in the calculations. I commented on the...

Aug 21, 2009 · Nonheaded anchor bolts, either bent or straight, having properties conforming to Specification A 36 (tensile strength of 58 to 80 ksi (400 to 550 MPa)) and intended for structural anchorage purposes. As to yield strength, in table IV of the spec it specifies the yield point as 36ksi minimum but only for grade C.

Jan 3, 2005 · The minimum yield strength by definition, is the stress (measured load/original cross sectional area of the tensile specimen) where permanent deformation occurs during a tensile test. Permanent strain deformation can be established from tensile load versus deformation data using either 0.2% offset or by drop of the beam method.

Jan 15, 2004 · After you weld, you have Aluminium 6061-0 at the weld, which has a yield strength of 8ksi. I have a chart here in an old catalogue that lists a yield stress of 14ksi for Aluminium 6061-T6 and 4043 filler alloy. If I were serious about all this, I would send my weldment out for heat treatment when I was done.

Apr 9, 2004 · My machine design textbook (V.M.Faires) recommends safety factors of between 1.5 for dead loads based on the yield strength of ductile steel, to 20, for shock loads based on the ultimate strength of cast iron or timber.

Mar 14, 2002 · I have been asked to advise a bridge designer concerning the material used to build a bridge in 1959. The construction specs of that era indicate that the bridge should have been made from ASTM A373 steel (or ASTM A7 if not welded). The bridge plans indicate the deisgner asked for ASTM A373...

Feb 3, 2015 · This is helpful but ASTM A15 was available in 33 ksi, 40 ksi, and 50 ksi strengths. Does anyone know what reinforcing yield strength was typically specified in the early 1950's? Using fy = 33 ksi, some of the existing members do not 'work' so I suspect the actual yield strength is greater than 33 ksi.

Oct 15, 2008 · The "expected" yield stress in this case would refer to the minimum yield stress multiplied by some factor (don't know the name of it) to give an estimated actual yield stress of the material. This is done to ensure that connections will be stronger than the expected material yield stress in order to ensure ductility away from the connections.

Aug 20, 2005 · Note that EN yield strength = Rp0.2 and ASTM yield strength = ReH (for carbon steel). The difference between the two values is about 10 MPa in some cases. -In EN standards the %C should be limited to 0.25 in product and %CE to …
