The material traditionally used for the structures of oil storage tanks – hot-rolled low-alloy plate steel 09G2S – rapidly decreases in strength with an increase in the thickness of the plates and becomes more susceptible to brittle fracture. The material does not provide the necessary resistance to the initiation of hydrogen-induced corrosion cracking and is not reliable or safe enough for use in storage tanks. The low strength of this steel makes it impossible to blast-proof these structures. The solution to these problems is the development and use of new rolled plates with excellent service properties. One steel that meets these needs is steel 08G2NMFB, of strength class 390. This steel has good weldability and is highly resistant to brittle fracture. Its use will ensure a high degree of reliability and safety in the operation of large storage tanks and provide significant technical-economic benefits.
