Hot continuous rolling can be divided into ordinary carbon structural steel, low alloy steel and alloy steel according to their different materials and properties. According to the different uses, A572 Gr 55 ms steel coil it can be divided into: cold forming steel, structural steel, automobile structural steel, corrosion-resistant structural steel, mechanical structural steel, welding gas cylinder steel and pressure vessel steel, pipeline steel, etc.
Our prime quality high strength structural stel plates retain the acidic attacks in tough climatic environments. These steel plates are heat-treated at very high temperatures of the heat; further, these are cold and hot workable steel. Our plates and sheets have excellent superior weldability. A572 Gr.50 dual certified plates A572 Gr 55 ms steel coil undergo many tests after the production such as corrosion test, pitting corrosion test, flattening test, flaring test, radiographic test and so on.
In order to further transform the operation mechanism, establish the operation concept of "market-oriented, customer-centric", strive to improve our core competitiveness and promote the rapid development of business; further strengthen customer marketing management, subdivide customer groups, establish a top-down, crisscross, hierarchical marketing mechanism of "everyone is a marketer", and provide for the needs of different levels of customers Corresponding services.
The deoxidation ability of Al is much stronger than that of Si and Mn when aluminum element (Al element) is added into steel as deoxidizer or alloying element. The main role of aluminum in A572 Gr 55 ms steel coil etc. steel is to refine grain size and fix nitrogen in steel, so as to significantly improve the impact toughness of steel and reduce the tendency of cold brittleness and aging. Al element can also improve the corrosion resistance of steel, especially when used with molybdenum, copper, silicon, chromium and other elements. The wear resistance of chromium molybdenum steel and chromium steel can be increased by containing Al element.
