Manufacturing technology of 09CuPCrNi-B steel equivalent

Cold rolled coil products 09CUPCRNI-B steel equivalent have accurate size and uniform thickness, and the thickness difference of coil is generally less than 0.01-0.03mm or less, which can fully meet the requirements of high precision tolerance. The surface quality of cold rolled products 09CUPCRNI-B steel equivalent is superior, and there are no defects such as pockmarks, pressing iron oxide scale and so on, which often appear in hot rolled coils. According to the requirements of users, coils 09CUPCRNI-B steel equivalent with different surface roughness can be produced (glossy surface or matte surface, etc.).

TMCP process is an important means to improve the comprehensive properties of steel. It can be used to produce ship plate, vessel plate, boiler plate, bridge steel, etc. Compared with the normalized steel of the same strength grade, TMCP can reduce the alloy content of the 09CUPCRNI-B steel equivalent steel, reduce the carbon equivalent and improve the welding performance. TMCP is more and more widely used in various types of steel rolling industry.

Company through its own 09CUPCRNI-B steel equivalent website, multimedia, radio, newspapers, the group, the handbook of the corporate culture carrier, approved and publicity column, in-depth to carry out enterprise culture construction, also through photography, painting, calligraphy, cartoon, speech, and the songs of the enterprise design, various cultural and sports activities to carry out enterprise culture construction.
