Basic knowledge about carbon content of NM400

In today's carbon content of NM400 steel market, most of the varieties are in excess of demand, especially after China's accession to the WTO, steel enterprises are facing increasingly fierce market competition. In order to make enterprises win a good survival and development space, operators must make effective use of carbon content of NM400 market information resources to improve the scientificity of business decision-making and enhance the enterprises' domestic competitiveness Competitiveness in the external market.

carbon content of NM400, NM series wear-resistant plates combine high hardness, high strength and high toughness, suitable for those severely worn occasions. The high wear resistance of the wear plate extends the service life of dump truck bodies, excavator buckets, crushers and similar equipment. The hardness of the wear-resistant steel plate is obtained through an effective quenching process. This method can not only achieve higher hardness, but also maintain a lower alloy composition in the steel. The produced wear-resistant plates are easy to machine, twist and weld.

According to GB 11251 technical standard, the chemical composition of 40Cr structural steel plate is as follow: Carbon content is 0.37-0.44 %, Silicon content is 0.17-0.37%, Manganese content is 0.50-0.80%, Chrome content is 0.80-1.10%. 40Cr steel is usually in shape of 40Cr steel plates and bars. carbon content of NM400, GB 11251 is for 40Cr structural steel plate with thickness range of 4-30mm. The tensile strength of 40Cr structural steel plate is 550-800Mpa. And its min. Elongation is 16%.

If customers have any difficult problems during use of the steel materials, they can contact the company's after-sales service department to feedback the existing problems. The after-sales department will reply as soon as possible to ensure that each customer has a good after-sales experience. Under special circumstances, the after-sales service department will start the problem-solving process, and the engineers in charge of the area will quickly follow up to solve the problem.
