Yield strength development from high strength steel plate
Jan 05,2016·The yield plateau of X70 steel is even larger than 4%.As listed in Table 3,yield strength (YS),ultimate tensile strength (UTS) and YS/UTS ratio increases with the upgrade of steel strength,while the elongation decreases dramatically with the increasing steel grades.The elongations (EL) of two high-grade steels (X80 and X90) are about 32% lower than X70 steel.
