Main application of S690QL rockwell hardness

"Novel coronavirus pneumonia has been closed in recent years, and Pohang iron and Steel Co., Ltd. closed its overseas processing center in Italy, Malaysia, Philippines and India. At the request of the Italian government, all production activities will be stopped except for the necessary S690QL rockwell hardness products. POSCO-ITPC, an Italian stainless steel cold rolling mill near Verona in northeast Italy, is scheduled to close from March 26 to April 3. The center has an annual processing capacity of 40000 tons of S690QL rockwell hardness stainless steel processing plant. POSCO-MKPC in Malaysia and POSCO-PMPC in the Philippines have been closed on March 17 and 18 respectively, and will be closed to the end of March. In addition, POSCO's rolling plate processing center in India will also be closed to March 31 as instructed by the local government of India."

S690QL rockwell hardness smelting method
The smelting process of electric furnace + external refining and vacuum degassing can be used for secondary electroslag remelting smelting. The steel plate should be intrinsically fine-grained steel, belonging to the 1.25Cr-0.5Mo series of pearlite heat-resistant steel, with good high-temperature strength, oxidation resistance, and sulfide corrosion resistance below 500°C. It is widely used in coal chemical industry and petroleum High temperature and high pressure vessel installation in the chemical industry.

In November of 2015, Thailand one company contacted with us from Internet. They are find the trustable supplier of S355J2H seamless pipe S690QL rockwell hardness for there cable car supporter. Due to the special using of the pipes, they are very careful and servious when choosing the supplier. After one months contact and discussion by email, they come to our company. We drive to the pipe mill for visit of 2 days. Through this visit, they are very confident with our production ability and proucts quality. Finally, they accept the grade we suggest Q345D. After back to office, they put the order of 1400 tons pipe to us directly.

The company has a high-quality management, technology and R&D team, and adopts independent research and development, domestic innovative process optimization combination. Relying on advanced manufacturing technology and sophisticated production testing equipment, it has ensured the high quality of products S690QL rockwell hardness and won a good reputation. We can offer various kinds of steel materials in GB, ASME, ASTM, JIS, DIN, EN, API standards and specifications.
