07MnNiMoDR quenched and tempered cryogenic container plates Introduction

07MnNiMoDR quenched and tempered cryogenic container plates Introduction

In 2008, in the Tianjin Petrochemical Ethylene Project, the ethylene/propylene spherical tank with -50°C low temperature impact was made of domestic 07MnNiMoDR steel plate, replacing the imported Japanese JFE-HITEN610U2L steel plate. As a steel with low weld crack susceptibility, 07MnNiMoDR steel plate is widely used in high-end fields such as petroleum, chemical industry, power station, boiler, reactor and heat exchanger. spherical cans and other high-end products.
