ASTM A 516 or ASME SA 516

At Oakley Steel, ASTM A 516 or ASME SA 516 grade is one of the most popular steel grades we sell.

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%


We supply 516 60 and 516 70 in a wide range of sizes and thickness. These range from 3mm to 150mm in thickness. Plate sizes can be up to 3m wide by 12m long.

Like all our steel these plates come from some of the best European mills so you can be sure of the quality that you are buying. Material certificates are available on request.
