It indicates that the yield strength of Q345B steel is isotropic in tensile and compression tests. Experimental and constitutive model study of structural steel q345b steel properties pdf yield strength In order to get a clear hardening relationship of steel and strip the effect of steel yield strength, the stress and strain are regularized into Eq. (2) . Material parameters and the regularized parameters of Q345B and Q235B are summarized in Table 4 .
The tensile test of Q345 steel naturally cooled at room temperature (20C, 250C, 500C and 750C) was carried out, and the variation law of the mechanical properties parameters such as stress-strain curve, yield strength, ultimate strength, elastic modulus and elongation with the increase of temperature was obtained.

permanently deform. Thus, it is important to design a casting for stress levels below the yield strength or in the elastic region of the part. Typically1/2 the yield strength is used for safety, but 2/3 can be utilized with a thorough evaluation. The strength of steel depends on the composition and heat treatment.
