Properties nm400 weathering steel for seamless pipe

A514 steel plate is high strength weldable steel quenched and tempered according to ASTM standard. ASTM A514 steel plate is mainly used in places where NM400 weathering steel high tensile strength and high yield are required. The lifting gears of engineering vehicles, and racks for offshore platforms generally use A514 grade Q or A514 Gr Q. The NM400 weathering steel hardness of A514 steel plate is between 235-290. A514 steel yield strength is more than 630MPa, and tensile strength is more than 700MPa. A514 steel plate is difficult to process. In the United States, the use of A514 steel plate is very large.

Weather-resistant steel plate refers to steel plate that is resistant to weathering and corrosion. NM400 weathering steel, Weather-resistant steel plate can adapt well to the environment and is widely used in construction, bridges, roads and other fields with outstanding performance characteristics. One of the outstanding advantages of weather-resistant steel plate is its ability to adapt to a variety of different environments, whether it is in severe cold areas or tropical areas. The weather-resistant steel plate can better maintain its characteristics in various complex environment.

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 NM400 weathering 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 NM400 weathering steel seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.
