More Details About SA612

Advantages/Disadvantages

SA612 is a high value pressure vessel quality steel plate. PVQ steel plates are specifically certified to contain liquids and gasses under ambient conditions. This grade provides good notch toughness and can tolerate moderate to lower temperatures.

Industries

The grade is fully killed, or deoxidized to meet mechanical standards required by oil, gas, and petrochemical industries for use in fusion welded industrial boilers and pressure vessels.

Applications

The grade is best for use in pressure vessels and industrial boilers. It is also ideal for other applications with exposure to moderate and low temperature conditions, and where high strength is required.

Machining

It has good machinability.

Welding

It has excellent weldability.

Heat Treatment

It is heat treatable.

Frequently Asked Questions About SA612

What is the tensile strength of SA612?

The ultimate tensile strength for this high carbon steel falls between 560 – 695 MPa, or 81,200 – 101,000 psi.

What is PVQ steel?

PVQ, or Pressure Vessel Quality steel, specifies general requirements for steel plates for pressure vessels. As pressure vessels often contain hazardous gases or liquids, the steel must show high-strength and retain pressure without cracking. Deoxidation of the steel plates conform to PVQ specifications for fine grain, which, along with its specific chemical composition, makes the steel impact resistant.

What limits the maximum thickness of SA612?

This steel plate, and other PVQ carbon plates, have a maximum thickness that is limited by the ability of the steel to meet mechanical property specifications set by the ASTM.
