Q550B steel is a low-alloy high-strength structural steel grade. Steel Q550A is not required for impact toughness test; Q550B is for impact toughness test at room temperature (20℃); Q550C is for 0℃ impact toughness test; Q550D is for impact toughness test

Q550B steel is a low-alloy high-strength structural steel grade. Steel Q550A is not required for impact toughness test; Q550B is for impact toughness test at room temperature (20℃); Q550C is for 0℃ impact toughness test; Q550D is for impact toughness test at -20℃; Q550E grade is for impact toughness test Make impact toughness test at -40℃. The impact toughness test uses Charpy V-notch specimens. The impact toughness index is Akv.

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 SA573 Grade 65 steel shapes 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.

Hardfacing wear-resistant steel plate is a kind of wear-resistant steel plate with double-layer structure. In order to make it into wear-resistant parts better, it is necessary to weld and assemble the wear-resistant steel plate, SA573 Grade 65 steel shapes. In order to ensure the original comprehensive performance of hardfacing steel plate, the base layer, transition layer and clad layer should be welded respectively. During the welding of hardfacing wear-resistant steel plate, the welding shall be carried out in strict accordance with the drawing, welding process and relevant standards.

The results of adopting two-level SA573 Grade 65 steel shapes service system and implementing standardized management are mainly reflected in the formation of vigorous work style such as quick response and quick action. Our company's customer service center stipulates that employees must be accurate and quick in technical support and SA573 Grade 65 steel shapes after-sales service. Through the formation of this fast, agile, vigorous style, to provide users with satisfactory service.
