A573 gr 58 carbon structural steel shape 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.

A573 gr 58 carbon structural steel shape, Q345 and Q345B are steel numbers. The differences are as follows:1. Q345 is general and does not indicate the quality level; Q345B is clear and the quality level is B.2. Q345 does not require to inspect the impact performance; Q345B requires that the impact performance at room temperature is qualified (impact at 20 ℃).3. Q345 does not indicate carbon content of steel; Q345B carbon content is 0.20%.Q345 refers to carbon structural steel with yield point (σ s) of 345MPa. The following letters indicate the quality level, including A, B, C, D and E.

We supply 5800 tons A53 Gr B ERW pipes to Qatar for Qatar Integrated Railway Project - Green Line. This is the first Metro Line in Qatar, and it is located in Doha. We got the order by tender, launched by the Qatar Railways Company for designing, construction and completion of Green Line Project. Before putting order, a delegation from the A573 gr 58 carbon structural steel shape project side visited us and several other famous steel pipe mills in China for 15 days. Finally, we were chosen and finished the task exceeding their expectations.
