ASTM A516 Grade 70 Steel Plate

ASTM A516 Gr.70 steel may contain much higher chromium levels, and additional alloying ingredients like molybdenum, nickel, titanium, aluminum, copper, nitrogen, phosphorous and selenium. ASME SA 516 Gr.70 steel is an economical and practical choice for most environments, but it doesn’t have the chloride resistance.

The most common grade, ASTM A516-70, is a medium carbon alloy designed for use in pressure vessels and boilers. Another trade name for A516-70 plate is PVQ Plate (Pressure Vessel Quality). Pressure vessel grades play a vital role in a variety of demanding applications, including oil and gas and power generation.

ASTM A516 Grade 70 Steel Plate is a high strength metal, easy to fabricate and can be securely welded. A516-70 plate also has low corrosion properties. This standard has been approved for use by offices underneath the jurisdiction of the Department of Defense.

Precision Grinding is your source for ASTM A516 steel plate products and shapes cut to size, ground, machined and processed into steel parts.

This specification covers carbon steel plates intended primarily for service in welded pressure vessels where improved notch toughness is important. A516 plates are available in four grades: Grades 55, 60, 65, and 70, according the different strength levels.
