General Product Description

Strenx® P700 is a pressure vessel steel with minimum yield strength of 97 - 101 ksi depending on thickness.

Strenx® P700 is available in four grades, which meet and exceed the requirements of P690Q, P690QH, P690QL1 and P690QL2 in EN 10028-6.

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

Dimension Range

Strenx® P700 is available as plate in thicknesses of 0.157" – 3.937", widths up to 118,11" and lengths up to 575.983". More detailed information on dimensions is provided in the dimension program for Strenx® P700 at www.ssab.com.

Fabrication and Other Recommendations

Welding, bending and machining

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

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 1076°F.

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.
