It comes in four grades 55, 60, 65 & 70. At Oakley Steel we mainly sell 516 gr 60 and 516 gr 70. These grades cover a range of tensile strengths from 55 - 90 MPa and this versatility explains much of the specifications popularity. <BR clear=none><BR clear=none>For plates thinner than 40mm we normally supply them as rolled.
