What is nm400 steel tensile strength equivalent steel in GB standard

Every after-sales service shall have a detailed record of the customer's product problems and handling methods. The records shall be sorted into volumes and filed on a monthly basis, and submitted to the technical department for filing. The problems found in the after-sales service shall be summarized in a timely manner, discussed with the technical department, the quality inspection department and the production department, and a proper solution shall be proposed for the technical department to improve in a timely manner;

Precautions for procurement of NM400 steel tensile strength, corrosion resistant steel. First, thickness. According to the thickness, corrosion-resistant steel can be divided into thin plate, medium plate, thick plate and extra thick plate, and each thickness has different application fields. Second, the choice of length and width, which can be cut to required size. Third, standards, each country has its own standards, so when purchasing corrosion resistant steel, it depends on which country it is used. Fourth, it is better to let professionals to purchase NM400 steel tensile strength or corrosion resistant steel.

EN10025-6 S960QL structural steel plates are quenched and tempered high strength steel with yield strength of 590Mpa ~ 960MPa. NM400 steel tensile strength, S960QL steel plates have technical requirement of flaw detection, Z15 Z35 thickness direction performance requirements, high strength and high toughness requirements and so on.

NM400 steel tensile strength, 30CrMnSiA steel has good machinability, small processing deformation and good fatigue resistance. If 30CrMnSiA steel is used to make a tool, it is processed to the tool shape by rough machining. Mill the cutting edge with a cemented carbide milling cutter and polish it with a polishing machine. There should be no problem for the surface roughness reaching 3.2. 30CrMnSiA steel has high strength, sufficient toughness and good hardenability after quenching and tempering. After quenching and tempering, 30CrMnSiA steel can be used for grinding wheel shafts, gears and sprockets.

The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.

Since its establishment, the company has participated in several key railway and highway projects. After years of development, the company’s NM400 steel tensile strength domestic market has been exported to more than a dozen provinces and cities including Kunming, Shenzhen, Hunan, Sichuan, Shanghai, Nanjing, Heihe, Jilin, Inner Mongolia, and Xinjiang . International trade is exported to Kazakhstan, South Korea, Vietnam, South Africa and many other countries, and has been well received by customers.
