What are the operation principles to be followed in the nm400 wear resistant plate cutting process

The company always adheres to the NM400 wear resistant plate principle of "quality first, user first", and takes every cooperation seriously. It is our biggest wish that the steel material, specification and quantity can fully meet the requirements of users. With good reputation, high quality products and low price, we are willing to work together with old and new customers to create a great NM400 wear resistant plate cause. Customers are welcome to visit our company at any time. We are always ready to support you.

SKD12 features and applications: SKD12 is suitable for various hardware cold punching dies, and large and complex punching dies that can withstand greater impact.SKD12 characteristics: 1. Air quenching die steel has deep air quenching hardening performance; 2. High wear resistance, micro deformation, high hardenability, high compressive strength; 3. Carbide distribution is more uniform than Cr12 steel.

It has good toughness. By strictly controlling the chemical composition, reducing the content of NM400 wear resistant plate harmful elements and selecting reasonable heat treatment conditions, NM360 steel plate has good toughness. Therefore, the highly reliable structural parts can be constructed according to the brittle failure of wear-resistant components. Uniform and beautiful quality, NM400 wear resistant plate using advanced technology and equipment, combined with high and scientific technical management, the material and shape of the product are even and consistent.

After extrusion, the NM400 wear resistant plate tube shall be removed for sizing. The sizing machine uses a cone-shaped bit to rotate into the steel embryo at high speed to drill holes to form steel pipes. The inner diameter of the steel pipe is determined by the outer diameter length of the drill bit of the sizing machine. After sizing, the steel pipe will enter the cooling tower and be cooled by water spray. After cooling, the steel pipe will be straightened. After straightening, the steel pipe is sent to the metal flaw detector (or hydraulic test) by the conveyor belt for internal flaw detection.

Hardness comparison between Q345B steel and NM450 steel: wear resistant steel for construction machinery requires high wear resistance, high toughness, impact resistance, easy welding, easy forming and other high-performance characteristics. The main index of wear resistance is the surface hardness. The higher the hardness, the better the wear resistance. Compared with NM400 wear resistant plate, Q345B steel, the hardness of NM450 steel is only increased 3 times, but the average service life is increased 6-8 times under the same working conditions.

We have our own factory, including the production and manufacturing of steel pipes, with a special NM400 wear resistant plate steel pipe manufacturer and storage warehouse. Welcome to visit our factory, we will provide customers with high quality products that meet the requirements. And has the perfect NM400 wear resistant plate after-sale service guarantee system, lets the customer save the worry and the labor.

We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.
