Per Shigley, the proof strength is approximately equal to 85% of the tensile yield strength, S ty.Based on S proof = 0.85·S ty, the recommended preload force as a function of yield strength is:. Considering that the above values are conservative, a general rule of thumb is to preload the fastener to 2/3 of the yield strength (i.e. % yld = 66.7%). Chinese GB Standard - The World MaterialQ345 Steel Properties Q345 steel is a Chinese GB standard Low Alloy High Strength Structural Steel, material density is 7.85 g/cm3, tensile strength is 470-630 Mpa, and yield strength is 345 MPa, it has better properties than Q235.

Q235 steel is equivalent to Japenese steel grade SS400 in application, the only difference is that ss400 steel requires only S,P composition < 0.050, Q235 has requirements for More element C, Si, Mn, S, P. Yield strength of q235 is >235Mpa, which is almost the same to SS400 245Mpa. Q represents the yield of this material, the latter 235, refers to the yield value of this material, at about 235MPA. PART IX:LAG SCREWSa yield strength of 45,000 psi and a tensile strength of 77,000 psi. Where lag screws having other strength properties were used, withdrawal design values and in withdrawal when the axis of the screw is at angle of approximately equal to the tensile strength of the lag screw. However, because tabulated withdrawal design Practical thread strenght analysis - TribologyThe ratio of shear strength to tensile strength of the SG cast iron is taken as /=0.9, where the tensile strength is =500 MPa. Solution:The ratio of shear strength of the bolt and the tapped hole is 0.58 1000 / 0.9 500 = 1.3. The required length of thread engagement becomes 1.3 0.8d = 12.5 mm.

Q235B is the most common used among carbon steel.It is equal to steel grades ASTM A36,JIS G3101 SS400,EN 10025-2 S235JR.Xinsteel stocks carbon steel Q235B in coils shape and plate shape at port warehouses with many sizes.

The MS angle options include Equal angles, Unequal angles as well as in different lengths as specified by the customers. These can also be cut to size and delivered as specified by the customers. Further, for delivering superior end performance, these also come tested for mechanical properties that include Tensile Strength, Elongation at gauge Tension CalculatorThis tension calculator will help you determine the tension forces acting in a rope, string, or any tension members that undergo pulling or stretching forces. You can calculate for tension forces in ropes pulling objects on a frictionless surface as well as tension forces in ropes that are suspending an object. To Determine Yield Strength & Tensile Strength of a Steel Then on the stress-strain diagram, lay off om equal to the specified value of the offset (i.e. yield strength ~0.2%), draw mn parallel to OA, and thus locate r, the intersection of mn with the stress-strain curve corresponding to load R, which is the yield strength load. In recording values of yield strength obtained by this method, the value

When stresses less than the tensile strength are

Tensile strength of 20# steel is not less than 410, yield strength is not less than 245, and mechanical properties of A36 are about the same. Comparison of A36, SS400 and Q235 plate:As can be seen from data above, ASME standard A36 and China standard Q235 materials are named according to yield strength of material, and for SS400 is tensile
