S460 steel grade equivalent prices rose again by a large margin

Q460 series steel means that the plastic deformation of the steel material reaches 460 MPa, that is, when the external force is released, the steel can only maintain the shape of the force and cannot return to its original shape. This strength is greater than that of ordinary steel. The general quality grade symbols are respectively A, B, C, D, E. On the basis of ensuring low carbon equivalent, Q460 appropriately increases the content of microalloying elements. Good welding performance requires low carbon equivalent of steel S460 steel grade equivalent, and the increase of microalloying elements increases the strength of steel while also increasing the carbon equivalent of steel.

S460 steel grade equivalent 2020 spot size: 16*1800*6000, 15*2500*10000, 25*2400*8200, 50, 25*2400*8200, 16*2000*10713, 25*2400*8200, 16*2270*11900, 15*2500*10000, 25*2400*8200, 28*2170*13000, 130*2200*7700, 100*1770*6650, 88*3440*9200, 12*2200*8000, 8*2200*5730, 16*2320*10000, 30*2400*9680 12*2200*8000, 16*1800*6000, 50*1820*10700, 130*2200*7700.

Preheating cutting: The most effective way to prevent steel plate cutting cracks is to preheat before cutting. Before flame cutting, the steel plate is usually preheated, and the preheating temperature mainly depends on the quality level and thickness of the steel plate. The preheating method can be carried out with flame burner, electronic heating pad, or heating furnace. In order to determine the preheating effect of the steel plate, the required temperature should be tested at the heating point.

The European Iron and Steel Industry Union (Eurofer) has sent a letter to the president of the European Commission, asking the Commission to review the existing trade safeguard measures immediately, proposing to reduce the steel import quota by 75% within six months to help the European steel industry cope with the current difficult situation; For imported steel exceeding the quota, the tariff rate can be reduced to less than 25%. Europe has also proposed restrictions on S460 steel grade equivalent and so on steel imports related to crisis and safety.
