The EN10083-3 alloy steel 27MnCrB5-2 plate plasticity from BBN
The salesman of the company is familiar with all aspects of knowledge. Understand the company profile: group, company profile, various honor certification, enterprise's functional strength and other advantages analysis. Know the main product brand types and specifications of the company, and know the special knowledge of the product (production process and advantages of the product, simple identification method of product quality, etc.)
The surface quality of pickling coil is very good. Compared with ordinary hot-rolled plate, EN10083-3 alloy steel 27MnCrB5-2 plate, the surface quality of hot-rolled pickling coil is improved in addition to the oxide scale on the surface, which is convenient for welding, oiling and painting. The accuracy of pickling coil specification is high. After leveling, the shape of the plate changes to a certain extent, thus reducing the deviation of unevenness, improving the surface finish and enhancing the appearance effect of pickling coil.
