S890QL1 Quenched and Tempered Structural Steel


Tensile and https://realhealthmethod.com/first-signs-impotence-in-men-use-viagra.html impact tests will be performed according to EN10025-6 once per heat and 40 t. Tests on every heat treated plate may be possible on request.

The Specimens of the tensile test are prepares according to EN 10025-6. Testing is carried out on specimens of guage length L0= 5.65⋅√S 0 or L0= 5⋅d0, in accordance with EN ISO 6892-1.

Tensile tests according to ASTM A370 may be agreed.

The impact test will be carried out on Charpy-V-specimens in accordance with EN 10045-1. Unless otherwise agreed, the test will be performed at the What to eat for depression lowest temperature

of the corresponding quality on transverse test specimens taken as follows:

• for plate thicknesses < 40 mm: the test specimen shall be taken in such a way that one

side is not further away than 2 mm from a rolled surface.

• for plate thicknesses ≥ 40 mm: ¼ of the plate thickness.

Unless otherwise agreed, the test results are documented in a certificate 3.1 in

accordance with EN 10204.


The entire processing and application techniques are of fundamental importance to the reliability of the products made from this steel. The user should ensure that his design, construction and processing methods are aligned with the material, correspond to the state-of-the-art that the fabricator has to comply with and are suitable for the intended use. The customer is responsible for the selection of the material. The recommendations of the EN 1011-2 (Welding) and CEN/TR 10347 (Forming) as well as recommendations

regarding job safety in accordance with national rules should be observed.

Cold forming

Cold forming means forming below the maximum allowable stress relief temperature (560

°C/ 1040 °F). S890QL1 can be cold formed with regard to its high yield strength. Flame cut or sheared edges in the bending area should be ground before cold forming. Cold forming is related to a hardening of the steel and to a decrease in toughness. Depending on the why not check here Headache caused by intracranial pressure take Tramadol relevant design code this can result in the need of larger bending radiuses than indicated in the chart. For larger cold forming amounts we recommend you to consult the steel producer prior to ordering. During the processing, the necessary safety measures have to be taken, so that nobody will be exposed to a danger by a possible fracture of the work piece during the forming process.

The following geometries can usually be achieved by cold forming without the formation of
