The company was established in 2000, covering an area of more than 4,500 acres. It has fixed assets of 200 million yuan, and employs more than 1,200 people. It has now formed coking, sintering, white ash, pellets, ironmaking, steelmaking, steel rolling, oxygen production, gas and waste heat The complete circular economy industrial chain including power generation, comprehensive utilization of slag, soot and dust treatment, sewage treatment and recycling, etc. It mainly produces hot-rolled steel plates and carbon structural steels, high-quality carbon structural steels, low-alloy high-strength steels, medium and wide-band steels for cold-rolled stamping, and hot-rolled coils.
EN10025-3 S275N steel is a normalized or normalized rolled weldable fine grain structural steel grade. S275N plates shall be under normalized delivery condition and be done low temperature impacting test at -20℃when rolling. If customers request the limited for some chemical compositions, such as P and S,our mill also can satisfy this strict request when processing owning to our highest technical. For the available thickness, , S275N plate is supplied up to 250mm,A514 grade M alloy steel plate.
Corrosion resistant steel plate, as a new generation of advanced steel material, has 2-5 times of atmospheric corrosion resistance as ordinary carbon steel such as A514 grade M alloy steel plate, and the longer the service time, the more prominent the corrosion resistance. Due to its characteristics of rust resistance, coating free, thinning and consumption reduction, labor saving and energy saving, corrosion resistant steel plate can be applied to steel structures exposed to the atmosphere for a long time, such as buildings, vehicles, bridges, towers, etc., and can also be used to manufacture structural parts such as containers, railway vehicles, oil derricks, seaport buildings, oil production platforms, etc.
A514 grade M alloy steel plate,Steel production and rolling technology and equipment also pursue the continuity between processes, such as the continuous process between continuous casting and rolling mills, continuous casting slabs hot transfer hot charging, increased direct rolling, and continuous cold rolling processes The development of controlled rolling and controlled cooling technology that combines rolling and heat treatment has played a huge role in improving the properties of rolled materials,A514 grade M alloy steel plate.
A514 grade M alloy steel plate,Heat treatment specification and microstructure of 12Cr1MoV alloy plate:Heat treatment specification: quenching 970 ℃, air cooling; tempering 750 ℃, air cooling.
