SPV490Q introduction of steel plate material for large oil storage tanks

Wugang SPV490Q is a Japanese standard steel plate for boilers and pressure vessels, and implements the JIS G3115 standard. Corresponding to the national standard 12MnNiVR steel plate. The technical requirements are very strict. SPV490Q steel is a low-alloy, high-strength steel used in the manufacture of pressure vessels, mainly in the manufacture of oil storage tanks. The traditional quenching and tempering process (reheating, quenching + tempering) is widely used at home and abroad for production. The large-scale and lightweight of modern engineering structures put forward higher requirements for the comprehensive performance of steel used in pressure vessels, so the use of direct quenching + tempering process at home and abroad is actively carried out to gradually replace the traditional offline quenching and tempering process2. Compared with the traditional off-line quenching + tempering, direct quenching has the following advantages: the balance of strength and toughness and weldability will be improved; The omission of the reheating and quenching process reduces energy consumption and production costs6. Because direct quenching simplifies the processing process, the process is more compact and reasonable, and the direct quenching-tempering process has been rapidly developed in various developed countries in the iron and steel industry in recent years.
