Shearing Strength of SAE 1018 CRS

Shearing Strength of SAE 1018 CRS

Shearing Strength of SAE 1018 CRS

(OP)
Can someone please point me in the direction of this mechanical property?

Thank you in advance for your kind reply.

RE: Shearing Strength of SAE 1018 CRS

I urge caution with this.  The three decimal precision comes from the von Mises criterion for yielding, so the shear yield strength = 0.577 times the tensile yield stress.  The ultimate shear stress is more random, and the the ratio is variable.  I would use 0.6 (with an appropriate safety factor) or perform testing to obtain an accurate number.

RE: Shearing Strength of SAE 1018 CRS

Use caution on the yield strength of any cold drawn products. The specification say the strenght is "typical" meaning it is based on a specific diameter cold finished bar. As the bar increases in diameter the strength reduces. An example is a .5" dia bar and a 4" dia bar. the cold working which takes place in the .5 dia is a much higher percentage of the bar and thus the yield strength is higher while the 4" dia has a very small percentage of the bar actually cold worked.
