Hot Rolled usage of hardox 500 sheet for oil tank

Steel S275J0 is a carbon structural steel grade. Our mill can produce S275J0 carbon steel plates up to 400mm thickness. Generally speaking, as rolled condition for S275J0 carbon steel plate is Ok. Our mill would like to provide customers' normalized delivery condition if they indicate in their purchase order. usage of HARDOX 500 sheet, Structural steel S275J0 has a specified minimum yield strength at ambient temperature of 275MPa when plates thickness less than 16mm.

Our company was founded in 2000, which initially committed to providing high-quality steel usage of HARDOX 500 sheet products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export usage of HARDOX 500 sheet steel to the international market, opening up the international steel market.

The main applications of normalizing are as follows:① For low carbon steel, usage of HARDOX 500 sheet. The hardness of low carbon steel after normalizing is slightly higher than that after annealing, and the toughness is also better, so normalizing can be used as the pretreatment of cutting.② For medium carbon steel, normalizing can be used as the final heat treatment instead of quenching and tempering treatment, or as the preparation treatment before surface quenching by induction heating.③ Normalizing can be used in tool steel, bearing steel, carburizing steel and so on, which can eliminate or inhibit the formation of network carbide, thus obtaining the good microstructure needed for spheroidizing annealing.④ Normalizing can refine the cast structure and improve the machinability of steel castings.

The steel such as usage 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.
