Performance requirements of GL-EH 36 offshore engineering steel

As a common steel plate in the steel market, GL-EH 36 offshore engineering steel, manganese steel plate has the following characteristics. First, good toughness, stretching and crimping can be done well. Second, the bearing strength of manganese steel plate is good and it can bear a lot of gravity. Third, the GL-EH 36 offshore engineering steel, manganese steel plate is easy to weld, easy to process finished products, and its price is relatively low. Fourth, manganese steel plate has good corrosion resistance, and long service life. Fifth, the manganese steel plate has good mechanical properties, low temperature performance, good plasticity and weldability.

We guarantee to provide all technical data required by users within one hour to provide reasonable quotation; to provide GL-EH 36 offshore engineering steel reasonable quotation for products consulted by users within one hour; to provide investigation reception: we guarantee to receive the investigation of users at any time and provide various convenient conditions for users.

The yield strength of A40, D40, E40 and F40 GL-EH 36 offshore engineering steel is not less than 390N/mm^2, and the tensile strength is 510~660N/mm^2. A, D, E and F respectively indicate that they can be at 0° and -20 ° respectively. Impact toughness GL-EH 36 offshore engineering steel that can be achieved at -40℃, -60℃.

Both the cross rolling method and the extrusion method must first heat the tube blank or ingot, and the steel tube produced is called hot rolling tube. Steel pipes produced by hot working can sometimes be cold worked as required. There are two methods of cold working: one is cold drawing, that is, drawing the GL-EH 36 offshore engineering steel steel pipe through the drawing die to make the steel pipe gradually thin and elongate; the other is cold rolling, which is the method of applying the hot rolling mill invented by the menesmann brothers to cold working. The cold working of GL-EH 36 offshore engineering steel seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.
