RINA grade B steel is a kind of hot rolled general tensile strength steel. The RINA B grade steel plates have yield strength of 34,100 psi (235 MPa), and ultimate tensile strength of 58,000 - 75,500 psi (400-520 MPa). RINA steels come 4 grades in ordinary
60# is a hypoeutectoid steel, strength, hardness and flexibility are very high, plasticity is low when in the cold deformation, poor machinability, welding and hardenability, It will have a tendency to crack when in water quenching.
GB/T1591 Q345B H/I Beam/ channel steel is steel with less than 0.2 percent of its composition made up of carbon, less than 0.55 percent of its composition made of silicon and several impurities (mostly sulfur, chromium and nickel).
