After the steel plate is produced from the original factory, it will pass through a series of transportation and storage links and then be delivered to the processing workshop. During this period of time, the steel plate surface will contact with the air continuously, which will inevitably produce a layer of oxide skin. The oxide skin is a difficulty in the treatment process. It has high melting point, is not easy to burn and dissolve, increases preheating time, reduces cutting speed. Therefore, the surface of the S460QL chemical composition plate should be derusted before cutting.

Advanced typical figures and typical deeds are the embodiment and symbol of S460QL chemical composition enterprise spirit, outstanding ideas and vivid images, with strong demonstration, radiation and transmission effect. Without distinctive typical characters, there is no unique enterprise culture. In carrying out the construction of enterprise culture, the advanced enterprise culture should be typified. Vigorously excavate, discover, cultivate and summarize the company's S460QL chemical composition advanced models.

Q345E steel plate is a low-alloy high-strength steel plate with good low-temperature impact performance. The steel grade is composed of three parts: Q (Qufu in Chinese spelling) representing yield strength, yield strength value, and quality grade symbol. S460QL chemical composition, Among them: Q represents the yield strength; 345 represents the yield strength value, unit MPa; E represents the grade (passed -40 degrees impact test).

Hot Rolled Plates S460QL chemical composition MachiningAfter final forging/forming and Heat treatment process, all the pipe Fittings, Flanges, Fasteners, Etc. are sent for machining i.e. and preparation, O/D and I/D matching as per dimensional codes. An Expert Q.C. engineer is involved and he keeps constant vigil on every machining operation. Step machining is carried out as required by the codes. GO and NO-GO gauges are used to check the O/D & I/D of the fittings, Flanges, etc.
