Drilling and cutting of nm400 material specification

Large-thickness NM400 material specification, Z35 grade steel plate is a kind of extra-thick steel plate that is applied under specific environmental conditions, such as the key parts such as the turbine seat ring and guide vane of the generator set. It has high requirements for safety, reliability, and long service life. Develop 200mm-300mm thick steel plate of Z35 level, to ensure that the layer tear resistance reaches Z35 level. 300mm thick Z35 grade steel plate can be used not only in the hydropower industry, but also in the manufacture of other large key equipment, and has broad prospects.

The research methods of isothermal treatment of NM400 material specification, wear-resistant plate include many excellent technologies, such as optical microscope, transmission electron microscope, X-ray diffractometer and electron backscatter diffraction technology. With the increase of annealing temperature, the proportion of ferrite in wear-resistant plate will gradually decrease, and bainite will increase, while the retained austenite will be distributed in ferrite grain boundary and crystal in elliptical and fine strip shape.

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 NM400 material specification 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 NM400 material specification customer service center, and the technical personnel will give corresponding answers and on-site treatment according to the needs of users.

According to the different manufacturing processes, there are hot rolled steel pipes and cold drawn NM400 material specification seamless steel pipes. BBN sells seamless pipes of different sizes, weights and grades. Customers can choose between black NM400 material specification line pipes and galvanized line pipes. From 2-3/8" to 24", steel grade A, B, X42, X80.
