hardnes of hardox 500 sheet can stand the test
The steel such as hardnes of HARDOX 500 sheet delivered in the hot-rolled state has a certain degree of corrosion resistance due to the high temperature, so it can be stored in the open air. However, this layer of oxide scale also makes the hot-rolled steel surface rough and the size fluctuates greatly. Therefore, the steel with smooth surface, accurate size and good mechanical properties is required to be produced by using hot-rolled semi-finished products or finished products as raw materials and then cold rolling.
Our company's hardnes of HARDOX 500 sheet power boilers, heating furnaces of double bars, double high lines and medium and thick plates all adopt heat storage technology, which can fully use blast furnace gas; the ladle baking, Maerz active lime kiln and medium and thick plate heat treatment furnace all burn converter gas, which can improve the hardnes of HARDOX 500 sheet utilization rate of secondary energy and realize negative energy steelmaking in steelmaking process.
Steel logistics takes “steel” as the carrier, “logistics” as the operation, and “information” as the core. It integrates steel trade, e-commerce, and tripartite logistics as one. The flow of funds, information, and logistics promote each other and integrate with each other. Construction industry, metallurgy industry, information industry, modern logistics cross-industry. Our logistics service team will make sure our goods delivered to the leaving port on time.Makes you worry-free after sales.
From the name, we can clearly know that seamless pipe is seamless steel pipe, which is different from welded pipe. Seamless pipe is actually a kind of steel with hollow section. hardnes of HARDOX 500 sheet, Seamless pipe has many advantages, such as: 1, the compressive capacity of seamless pipe is very good, the place with high bearing strength will not crack, and its bearing capacity is very good. 2. Seamless pipe has no welding point, so it is more corrosion-resistant and can bear larger pressure.
