What is ASTM 516 Gr. 70?

ASTM A 516 or ASME SA 516 grade is one of the most popular steel grades in market .
ASTM 516 Gr. 70 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%
If you have questions regarding the scope of ASTM 516 Gr. 70 steel, please feel free to reach out to KATALOR steel, or visit our main steel plate products page for more KATALOR steel.
As with all our steels, our ASTM 516 Gr. 70 plates come with mill test certification and stampings and we can arrange for a variety of tests to be performed on the ASTM 516 Gr. 70 material if specified. Alternatively, the customer can arrange testing via a third party testing house.
