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 A572 grade 60 ms steel coil production, learning, research and marketing. Our company has passed ISO9001 quality management system certification and ISO10012 measurement management system certification.
The diameter of large diameter seamless steel pipe is 325mm-1220mm, and the maximum thickness that can be achieved is 200 mm. The diameter of small diameter seamless steel pipe is generally less than 89mm. The processing technology of large diameter seamless steel pipe is hot rolling or hot expanding. There are many materials for large diameter seamless steel pipe, such as A572 grade 60 ms steel coil, which can be processed and customized according to customer requirements. The large diameter seamless steel pipe is usually used in the chemical, petroleum, mechanical and other industries.
A572 grade 50 hot rolled plates and sheets are exhibiting features such as high tensile strength, oxidation and corrosion resistance, working ability, durability, long-lastingness, and formability. All these are responsible for making it the best selection. In addition to that these HR plates A572 grade 60 ms steel coil maintain the properties for a longer duration at the high temperature with no harm. The documents are also offered by us to our clients like MTC as per EN10204/3.1b, radiography test report, packaging list, size and quantity inspection and so on to give surety that only premium quality of the product is supplied to them.
Advantages of hot rolling: hot rolling can destroy the casting structure of ingot, refine the grain of steel and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the A572 grade 60 ms steel coil steel is no longer isotropic to some extent; the bubbles, cracks and looseness formed during pouring can also be welded under the action of high temperature and pressure.
Our A572 grade 60 ms steel coil, GB/T 1591-2008 Q460D plates are supplied with thickness up to 100mm. Below is our product stock list: 12*1730*8200, 28.58*2172*12100, 22.23*2181*12000, 28.58*2172*12300, 28.58*2171*12100, 35*2200*3500, 22.23*2182*12200, 28*3720*9400, 22.23*2182*12000, 35*2200*3800, 22.23*2125*12000, 24*3000*8850, 22.23*2075*12000, 14*2405*7610, 28.58*2172*12300, 48*2590*7000, 28.58*2172*11400, 75*1800*3500, 120*2040*9150.
