A516 Grade 485 (A516 Grade 70) material is a common kind of pressure vessel plates for welded pressure vessels where improved notch toughness is important.
Pressure vessel steel A516 Grade 485 has good impact resistance, low temperature deformation, good welding performance, good fatigue resistance, good anti-layered cracking performance, micro-alloying, high purity, low carbon equivalent, strong resistance to sulfur and hydrogen, good dimensional tolerance and good surface quality.
