12mm thickness A572 Grade 60 grade steel hot rolled sheet

The company adheres to green development, supported by scientific and technological innovation and technological progress, vigorously advocates the A572 Grade 60 grade steel production and life style of saving, environmental protection, civilization and low carbon, adheres to the new industrialization road and the sustainable development road. Actively carry out international trade and maintain stable economic and trade relations with more than 80 countries and regions including the United States, Germany, France, the United Kingdom, Japan, South Korea and Australia.

Steel materials A572 Grade 60 grade steel can be classified not only by chemical composition, main quality grade, main performance or use characteristics, but also by habit into carbon steel and alloy steel. Carbon structural steel is easy to smelt, has good processability, low price and large output, and can meet the requirements of common parts of general engineering structure in performance. Carbon structural steel A572 Grade 60 grade steel is usually rolled into steel plates and various sections, which are used for mechanical parts such as factory buildings and bridges.

Low-alloy steel plates have low carbon content, and because ferrosilicon is not used for deoxidation, the silicon content in steel is often <0.07%. The outer layer of rimmed steel is crystallized in a rimmed state, so the surface layer is pure and dense, the surface quality is good, and the Zhengzhou low alloy steel plate A572 Grade 60 grade steel has good processing performance. Rimmed steel does not have large concentrated shrinkage cavities, uses less deoxidizer, and the cost of steel is low.

The cold bending method is mainly used to produce cold-formed section steel and welded pipe. The cold bending method is to bend the steel strip or steel plate into various cross-section shapes by the cold bending machine in the cold state. If the A572 Grade 60 grade steel steel pipe is bent into a circular, square or other hollow shape and welded by a proper welding method, it is a welded pipe. The advantages of cold bending: first, the cold-formed section steel is light in weight and large in bearing capacity, and it can save metal by replacing the hot-rolled section steel; second, it can produce all kinds of A572 Grade 60 grade steel extremely thin, extremely wide and complex section steel which can not be produced by hot rolling.

The quality grade of common carbon structural steel Q235 can be divided into A, B, C, D and E. Relatively, the quality of Q235A is poor and that of Q235E is the highest. Different grades of Q235 steel have different characteristics, which are mainly different from the impact temperature: Q235A does not require impact toughness test; grade Q235B is for room temperature (20℃); grade Q235C is for 0℃; grade Q235D is for - 20℃; grade Q235E is for - 40℃. The A572 Grade 60 grade steel, carbon structural steel Q235 has good combination of strength, plasticity and welding properties.

After-sales service is an important part of measuring a product good or not. After sales service can't be ignored. Good service can really make consumers feel relieved. We have always done a good job in after-sales service, so as to bring consumers a better reference when purchasing and a better experience during use of our steel materials. We will call back and follow up the performance of our steel products regularly.
