ASTM a516 grade 70 steel plate is also known as ASME SA516-70. It is a medium-carbon alloy and also contains a large amount of manganese, phosphorus, sulfur and silicon. ASTM A516 grade 70 steel plate is mainly used in the service of welding pressure vessels, and the toughness of the grade needs to be improved.
A516 steel plate is the most popular pressure vessel quality steel plate. Although A516 steel plate has different grades, ASTM A516 grade 70 steel plate is the most common. ASTM A516 grade 70 steel plate is suitable for medium and low temperature applications, where gear toughness is very important. ASTM A516 grade 70 steel plate provides a good combination of strength, first-class toughness and weldability.
ASTM A516 grade 70 steel plate is considered a higher quality steel and a wider range of possible applications. The purchasers tend to choose ASTM A516 grade 60 steel plate or ASTM A516 grade 70 steel plate, while ASME SA 516 grade 65 is less popular. This is because the small difference between the grades means that many of the heat can be double or triple. In additional costs of purchasing ASME SA 516 gr 70 for procurement purposes is small , while the engineering and logistics benefits may be great.
