High strength carbon content of NM400 with 20mm coil thickness

Our company will set up a full-time service engineer for the project, who is responsible for the interface and coordination of technical support and after-sales service of the carbon content of NM400 project. In response process of customer service center, in case of technical support and after-sales service demand, the user shall contact the full-time engineer of carbon content of NM400 customer service center, and the technical personnel will give corresponding answers and on-site treatment according to the needs of users.

The secondary quenching and low temperature tempering of carbon content of NM400, wear-resistant composite plate is mainly used for important carburized parts with high mechanical properties, especially for coarse grain steel. However, after carburizing, it needs to be heated twice at high temperature to increase the deformation and oxidation decarburization of the workpiece.

carbon content of NM400, 15CrMo alloy steel is Chinese material. It is characterized by high Chrome and Molybdenum contents. The 15CrMo alloy steel chrome content is 0.80-1.10, and molybdenum content is 0.40-0.55. Besides, 15CrMo carbon content is 0.12-0.18, silicon content is 0.17-0.37, manganese content is 0.40-0.70. The heating temperatures for quenching and tempering of 15CrMo alloy steel are 900 and 650 centigrade respectively. The yield point of 15CrMo alloy steel is 295Mpa.

The company's business philosophy: customer satisfaction is the most important measure of our work performance; employees are the company's most important wealth; the improvement of employees' quality and professional knowledge is the growth of the company's wealth; employees' welfare and living standards are the concrete embodiment of the company's business performance; product and service quality are the lifeblood of the company's development; brand is the company's products and A mirror of service; recognition of the market is the foundation of the company's survival.
