Effect of grain size on yield strength ratio of S275ML steel plates

The deoxidization process of Q345R boiler vessel plate if the type and amount of deoxidizer are controlled to make a certain amount of oxygen remain in the S275ML steel plates steel, when sufficient amount of strong oxidant is added to make the steel deoxidize well, the co bubble will escape during the solidification process and generate boiling phenomenon, no co bubble will be generated during the solidification of the S275ML steel plates steel, the steel used for the pressure vessel of the killed steel is called the killed steel, this kind of steel is called the boiling steel.

Q690D steel material is a low-alloy ultra-high strength steel grade. Standard: GB/T 3077. The hardenability of steel is high, and the critical hardenable diameter in oil is 60mm (96% martensite). After quenching and tempering, steel can obtain high strength, and has certain toughness, and can be processed into shape. But cold deformation plasticity and weldability are low.
