About welding of hardox 500 plate for tube

ASTM A 53 HARDOX 500 plate for tube covers seamless and welded steel pipe with nominal wall thickness. The surface condition is usually black and hot-dipped galvanized. ASTM A 53 HARDOX 500 plate for tube is produced mainly for pressure and mechanical applications, and is also used for transport of steam, water, gas line pipes.

The company adheres to the "variety, quality and efficiency" road. We have established a technology center, a brand cultivation management system and a quality control system. Now the company has formed an independent innovation system integrating HARDOX 500 plate for tube production, learning, research and marketing. Our company has passed ISO9001 quality management system certification and ISO10012 measurement management system certification.

Both the cross rolling method and the extrusion method must first heat the tube blank or ingot, and the steel tube produced is called hot rolling tube. Steel pipes produced by hot working can sometimes be cold worked as required. There are two methods of cold working: one is cold drawing, that is, drawing the HARDOX 500 plate for tube steel pipe through the drawing die to make the steel pipe gradually thin and elongate; the other is cold rolling, which is the method of applying the hot rolling mill invented by the menesmann brothers to cold working. The cold working of HARDOX 500 plate for tube seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.

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 HARDOX 500 plate for tube 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.

We are willing to cooperate sincerely with you with high-quality HARDOX 500 plate for tube products and sincere service to expand the market and create brilliant!
