ASTM A516 Grade 70 Pressure Vessel Steel Plate
Masteel supply high quality Carbon Steel Plate for boiler and pressure vessel fabrication which is ideally suited to the high standards set by the oil, gas and petrochemical industry – this is why we stock an extensive range of carbon plates according to ASTM A516 Grade 70.
ASTM A516 Grade 70 is an excellent choice for service in lower than ambient temperature applications, has excellent notch toughness and is used in both pressure vessels and industrial boilers.
A516 Grade 70 offers greater tensile and yield strength when compared to ASTM A516 Grade 65 and can operate in even lower temperature service.

Pressure Vessel Steel Plate Introduction
Pressure vessel quality (PVQ) steel plate is used to produce pressure vessels due to its tensile strength, notch toughness, ductility and fatigue characteristics.
Before examining the properties of PVQ grades, here are a few terms used to describe the properties of steel, defined:
Strength: the load the steel can bear. Steel strength is determined by yield point and tensile strength. A yield point is the point at which a material is stressed to the point where it deforms but does not break. Tensile strength is the amount of stress needed for the material to break.
Notch Toughness: the level of impact steel can absorb before denting, typically measured by a Charpy Impact test.
Ductility: the capability of a material to be stretched out before it becomes weak or brittle. Ductility is measured by elongation, which is the percent the length of a stretched material increases before it breaks.
