ASTM A 516 or ASME SA 516 grade is one of the most popular steel grades in market .
It is primarily intended for use in welded pressure vessels where notch toughness is important. 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.
For plates thinner than 40mm we normally supply them as rolled. Plates supplied above 40mm thick are normalised.
For A 516 grade 70, which is one of our most popular steels, the ASME standard composition is as follows (dependent on grade):
Carbon 0.27 - 0.31%
Manganese 0.79 - 1.3%
Phosphorous 0.035% max
Sulphur 0.035% max
Silicon 0.13 - 0.45%
