Cold rolled coil products SA573 Grade 70 structural carbon steel angle bar 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 SA573 Grade 70 structural carbon steel angle bar 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 SA573 Grade 70 structural carbon steel angle bar with different surface roughness can be produced (glossy surface or matte surface, etc.).

Japan is a typical shipping first, and its raw materials are imported from Oceania, central and South America and other Asian countries. Most of the SA573 Grade 70 structural carbon steel angle bar steel produced is exported to China and other Asian countries, and a small amount is exported to America. Shipping is the main way of its SA573 Grade 70 structural carbon steel angle bar steel international transportation. According to the data, steel goods account for about 20% of the total sea freight in Japan. The domestic transportation of Japanese steel is mainly truck.

Fatigue wear often occurs on the rolling or rolling and sliding friction surface of the wear-resistant plate, SA573 Grade 70 structural carbon steel angle bar. Under the action of alternating stress, the soft area of the surface will produce plastic deformation. When the stress exceeds the tensile strength of the material, cracks will appear in the weak places, and the cracks will continue to expand under the effect of stress. When the crack length reaches a certain value, it will cause fracture and cause the phenomenon of pitting and spalling.
