Products Description
ABS EQ70 ship plate is an extra higher strength shipbuilding steel material which is mainly used for built hull of vessels,ship body construction and oil offshore platform.Normally when rolling,quenched and tempered would improve steel strength in yield and tensile points.Generally before using these ship plates ABS Grade EQ70,steel plate pretreatment is necessary.Pre-treatment including shot blasting and painting with shop primer.

What is the EQ70 steel plate?
EQ70 steel is a quenched and tempered high-strength steel plate for offshore platforms. The commonly used grades are EQ70 and EQ70-Z35.
Delivery status: quenched + tempered.
Application range of EQ70 high-strength steel plate for offshore platforms
Due to the erosion and destruction of natural forces such as sea waves, submarine earthquakes, and low temperatures, the requirements for various technical indicators of steel are extremely high, and the technical standards for steel for key parts such as racks and legs are more stringent. In order to realize the localization of steel for offshore platforms, GNEE steel began to develop 140mm thick quenched and tempered high-strength steel EQ70 in 2008, and it took 10 months to succeed. While the 140mm thick EQ70 achieved mass production, GNEE steel quickly invested in the research and development of this steel with a larger thickness. In 5 months, EQ70 high-strength steel with different thickness specifications such as 150mm, 180mm, 215mm, etc. have been developed and successfully passed the ABS classification society certification. This means that GNEE steel can produce all the thick plates of the high-strength steel series for offshore platforms in China.
