SA516 Gr60 steel plate smelting method
It is smelted by electric furnace + out-of-furnace refining, which is essentially fine-grained killed steel, and its actual grain size is 5 or finer.

SA516 Gr60 steel plate delivery status: normalized. Specimen state: All steel plates should be subjected to simulated post-weld heat treatment for their inspection samples. Recommended simulated post-weld heat treatment temperature: 620+15℃, holding time: 8 hours, the temperature is above 400℃, and the temperature is above 400℃. , if it does not conform to the recommended heat treatment system, the specific simulated post-weld heat treatment system shall be indicated in the contract.
