Strenx P700

Strenx® P700

Strenx® P700 is a pressure vessel steel with minimum yield strength of 670 - 700 MPa depending on thickness.

Strenx® P700 is available in four grades, which meet and exceed the requirements of P690Q, P690QH, P690QL1 and P690QL2 in EN 10 028-6.

Typical applications are demanding loadbearing structures exposed for pressure and elevated temperatures.

Dimension Range

Strenx® P700 is available in plate thicknesses of 4.0 – 100.0 mm, widths up to 3350 mm and lengths up to 14630 mm.

Welding, bending and machining

Recommendations are found in SSAB’s brochures at www.ssab.com or consult Tech Support, techsupport@ssab.com.

Strenx® P700 has bending guarantees according to Strenx® Bending Guarantees Class A. Workshop guidelines for Strenx® P700 refer to the same recommendations as for Strenx® 700 E. Strenx® P700 has obtained its mechanical properties by quenching and subsequent tempering. The properties of the delivery condition cannot be retained after exposure to temperatures in excess of 580°C.

Appropriate health and safety precautions must be taken when welding, cutting, grinding or otherwise working on this product. Grinding, especially of primer coated plates, may produce dust with a high particle concentration.
