hardox 400 china manufacturer price per ton
The steel market is full of good and bad, and the quotation is chaotic. The price of HARDOX 400 china manufacturer, spiral welded pipe is fluctuating. It is better to understand the market price of spiral welded pipe before purchasing. If it is a large project, the required quantity of spiral welded pipe is large, the price selection should be particularly careful, and we can select several suppliers for comparison. In addition, we shall not only consider the price, but also put an eye on the quality, the actual weight.
BEBON Iron & Steel has fully passed the ISO9001 quality system certification, marine steel has passed 9 countries' classification societies, and construction steel has obtained the CE Lloyd's CE Mark certification. The main body of HARDOX 400 china manufacturer steel passed ISO14001 environmental management system certification and OHSAS18001 occupational health and safety management system certification. The main HARDOX 400 china manufacturer production processes and technical equipment of the enterprise have reached the international advanced level, the comprehensive competitiveness has entered the international advanced ranks, and the international influence has been significantly enhanced.
S355J2 steel plate HARDOX 400 china manufacturer rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the rolling speed is 1.6-2.0m/s, the HARDOX 400 china manufacturer single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.
The addition of Ca element in steel such as HARDOX 400 china manufacturer can refine grain size, partly desulphurize and change the composition, quantity and morphology of non-metallic inclusions. It is similar to that of adding rare earth in steel. It can improve the corrosion resistance, wear resistance, high temperature and low temperature resistance of steel, improve the impact toughness, fatigue strength, plasticity and welding performance of the steel, and increase the cold heading, shock resistance, hardness and contact endurance strength of the steel.
Respect customers and treat each other sincerely. Customers are always right. Always remember that the user is the God of the enterprise, respect the customer, and accept the customer's opinion modestly is the guarantee of the long-term development of the enterprise.
