Do you know the differences between A515 grade 60 steel and A516 grade 60 steel? Below are the main comparison between them.
A515 grade 60 steel is a carbon-silicon steel plates primarily for intermediate- and higher-temperature service in welded boilers and other pressure vessels.
A516 grade 60 steel is also a carbon steel plates. It is intended primarily for service in welded pressure vessels where improved notch toughness is important.
