Supply heavy price of NM400 steel grade annealing

Is there a difference between seamless steel pipe and ordinary steel pipe? The general requirements of price of NM400 steel ordinary steel pipe are not so high, which are used in ordinary buildings or structures. According to the different materials and standards, seamless steel pipe will have different application environment. For example, seamless steel pipe for boiler requires pressure value. Seamless steel pipe for petroleum cracking also has its own corresponding national standard. Seamless steel pipe can be divided into fluid pipe, gas cylinder pipe, boiler pipe, oil pipe, automobile steel pipe, ship pipe, structural pipe, etc.

Wear Resistant Steel Plate refers to a special plate product designed for use under large-area wear conditions. At present, the commonly used wear-resistant plates are made of ordinary low-carbon steel or low-alloy steel with good toughness and plasticity by surfacing welding with a certain thickness of alloy wear-resistant layer with high hardness and excellent wear resistance. In addition, there are cast wear plates price of NM400 steel and alloy quenched wear plates.

Under the action of the roller and the plug, a cavity is formed in the blank, which is called the blank. Then send it to the automatic tube rolling machine to continue rolling. Finally, the wall thickness of the whole machine is equalized and the diameter is calibrated by the sizing machine to meet the specification requirements. It is an advanced method to produce price of NM400 steel, hot-rolled seamless steel tube by continuous rolling mill.

According to a report by yonhap news agency on April 26, under the impact of COVID - 19 epidemic, the steel industry chain was also affected. Hyundai lost 29.7 billion won. According to the report, the automobile and other downstream steel industry production stoppage directly led to a precipita-like decline in steel demand, is the main reason for the decline in steel enterprise performance of the main reason for hyundai said, hyundai kia motor production extension, by the end of April is expected to reduce production of 500,000 vehicles, as a result, price of NM400 steel, automotive steel demand will be reduced by 300,000 tons.
