20MnB5 carbon equivalent steel suppliers with certificates
Flat steel is divided into galvanized flat steel, carbon flat steel, stainless steel flat steel, etc. according to the material. Flat steel can be divided into hot-rolled flat steel and forged flat steel according to the forging process. 20MnB5 carbon equivalent steel, Hot-rolled flat steel is a potential-rolled long steel with a rectangular cross-section for general use. Forged flat steel is a long steel plate with a rectangular cross section that is forged. Hot-rolled spring flat steel is mainly used to manufacture leaf springs for automobiles, tractors, railway transportation and other machinery. The thickness of the flat steel is 8-50mm, the width is 150-625mm, and the length is 5-15m.
The research methods of isothermal treatment of 20MnB5 carbon equivalent steel, 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.
Rolling steel is the process of pressing to change the shape of the ingot and billet between the rotating rolls. The so-called steel rolling process is a combination of a series of steel rolling processes. The entire rolling production process is always composed of the following 20MnB5 carbon equivalent steel basic processes: ① billet preparation:Including the cleaning of surface defects, the removal of surface scale and the pre-heat treatment of billets. ② billet heating ③ steel rolling: it is the core of the entire rolling production process. ④ Finishing.
First of all, we should establish a correct concept of after-sales service. Service concept is an important part of corporate culture and a long-term enterprise value concept. Our company's after-sales service embodies the concept of "customer first, sincere service for customers". As long as we are in the "sincere service for users" under the guidance of the idea, I believe we will get rich returns.
