A516 Gr 70 Carbon Steel Plate

A516 Grade 70 is a medium- and low-temperature carbon steel plate widely used in pressure vessel manufacturing.

Composition characteristics: Low carbon (C ≤0.27%), high manganese (Mn 0.85-1.20%), with strictly controlled sulfur and phosphorus content to improve low-temperature toughness.

Mechanical properties:
Tensile strength: 485–620 MPa
Elongation: ≥21% (plate thickness ≤50 mm)
Hardness: ≤187 HB
