1 scope of application:
This technical specification specifies the size of WSD690E steel plate of 8mm-50mm thickness for Volvo
Shape • allowance deviation technical requirements test method inspection rule mark and certificate of quality etc..
2 Brand
The grade is WSD690E., and the quality grade symbol is E, which represents -40C degree impact test temperature.
3 size • shape • weight and allowance deviation
The size, shape and allowable deviation of the 2006 steel plate shall be in accordance with the provisions of GB/T709 - 3.1.
The thickness deviation of the 3.2 steel plate shall be in accordance with the C class deviation in GB/T709-2006 6.1.3.
The weight of 3.3 steel plate is calculated according to theoretical weight. The thickness of the theoretical weight is the allowable thickness and the thickness of the steel plate
The arithmetic mean, the density of steel 7.85g/cm fand.
4 technical requirements
The 4.1 grade and chemical analysis (melting analysis) shall conform to the provisions of table 1.

4.2 smelting method
Vacuum treatment should be done immediately
4.3 delivery status
The steel plate should be quenched and tempered in the quenched and tempered heat treatment state.
4.4 mechanical properties and technological properties
The mechanical properties and technological properties of WSD690E steel sheet should be in accordance with the provisions of Table 2 in delivery.

C according to table 2 cold bending test no crack.
4.5 ultrasonic inspection
The steel plate shall be executed at 100% JB4730.3 and shall comply with the I grade
4.6 surface quality
No bubbles on the surface of the steel plate. Scab • crack • folding • inclusion and pressed oxide scales. Steel plate shall not be layered.
The surface of the steel plate is allowed to have a thin oxide scale which does not impede the inspection of the surface defects
The surface roughness, scratch, indentation and other local defects, but its depth from the steel plate
The surface defects of steel plate can be treated by grinding, but the small thickness of the steel plate should be ensured, and the repaired parts should be smooth and without edges and corners.
Five
5.2 test method: each batch of steel plate inspection items • sampling quantity • sampling method and experimental method conform to the provisions of table 3.
5.3 steel plate with thickness greater than 40mmm, the impact test axis should be located at 1/4 of the plate thickness.
5.4 (Charpy V notch impact test results), does not comply with the provisions of article 4.4: from the same plate
3 samples were taken before and after the experiment, two groups of 6 specimens are only allowed to have 1 samples is less than the specified value, but does not allow for less than a prescribed value 70%.
5.5 the retest of other experimental items shall comply with the provisions of GB/T17505-1998
