The short-term price of xar400 plate equivalent grades is supported

GB/T1591-2018 Q355NB is a low-alloy high-strength structural steel. This steel has high strength, good fatigue resistance; high toughness and low brittle transition temperature; good cold forming performance and welding performance; good corrosion performance and certain wear resistance. Steel xar400 plate equivalent grades products are delivered in hot rolled, normalized, normalized rolled or thermomechanical rolled (TMCP) state.

The alloy steel plate has higher oxidation resistance and corrosion resistance, and is more suitable for use in acid and alkali environments. The surface of alloy steel plate will not be oxidized and corroded, maintaining the brightness of the steel plate. The alloy steel plate also has high material strength, its pressure bearing performance is very outstanding. It has high plasticity under the condition of long-lasting stretching. The xar400 plate equivalent grades, alloy steel plate is not prone to fracture, and it is more durable.

As the thickness and hardness of xar400 plate equivalent grades increase, the tendency to crack at the cutting edge increases. In order to prevent the xar400 plate equivalent grades from cutting cracks, preheating should be carried out before xar400 plate equivalent grades cutting. Special attention should be paid to preheating to make the entire xar400 plate equivalent grades interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole xar400 plate equivalent grades cannot be preheated, the partial preheating method can be used instead.
