Tolerances

More details are given in SSAB’s brochure Strenx® Guarantees.

Thickness

Tolerances according to Strenx® Thickness Guarantees.
Strenx® Guarantees meets the requirements of EN 10029 Class A, but offers narrower tolerances.
EN 10029 meets and exceeds the requirements for ASTM A6.

Length and Width

Tolerances on length and width according to ASTM A6.

Shape

Flatness

Tolerances on flatness according to Strenx® Flatness guarantee Class C, which are twice as good as the ASTM A6 flatness requirements. 

Surface Properties

According to ASTM A6.

Delivery Conditions

The delivery condition is Quenched and Tempered. The plates are delivered with sheared or thermally cut edges. Untrimmed edges after agreement.

Delivery requirements can be found in SSAB’s brochure Strenx® Guarantees.

Fabrication and Other Recommendations

Welding, bending and machining

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

Workshop guidelines for Strenx® 100 refer to the same recommendations as for Strenx® 700. Bending guarantees according to Strenx® bending guarante class A.

Strenx® 100 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 580ºC.

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.
