2 percent offset yield strength for both steels using marked points is presented in Fig.
2 percent offset yield strength of ASTM A505 steel are quite higher than at ASTM A709 steel.
2 percent offset yield strength, modulus of elasticity, fracture toughness, etc.

According to this report, resonant frequency or ultrasonic velocity measurements can be used to predict the effect of small changes in graphite form on the tensile strength, offset yield strength
and other properties of ductile iron castings of known similar matrix structure containing up to 70% non-nodular graphite.
Offset yield strengths
and hardness, however, do not seem to be significantly affected.
Tensile strengths were reportedly lowered by 20% but offset yield strengths
and hardness were relatively unaffected.
