1. Excellent mechanical properties
RINA GrE marine steel plate has excellent performance. Mechanical properties, yield strength of not less than 235MPa, to ensure the stability of the external force; tensile strength of 400 - 520MPa, can withstand large tensile force. 8-inch length elongation of not less than 21%, 2-inch length of not less than 24%, reflecting good plasticity and toughness. Especially in the low-temperature marine environment, need to have a good impact toughness to ensure stable performance.
2. controlled rolling delivery state
Delivery state is usually controlled rolling, the process of precise control parameters, improve the organizational structure and properties, so that the steel plate with excellent mechanical properties and high dimensional accuracy to meet the high standards of shipbuilding.
3. Wide range of applications
It is mainly used in the hull structure of ships and cranes and other key parts. Ship hulls need to withstand a variety of complex forces, the steel plate has high performance requirements in various aspects, RINA GrE marine steel plate can ensure the safe operation of the ship by virtue of its excellent comprehensive performance, widely used in icebreakers, polar transportation ships and other special ships.
4. Fine production process
The production process includes steelmaking, continuous casting, rolling and heat treatment. Strict control of chemical composition and reduction of impurity content in steelmaking; continuous casting to ensure the quality and uniformity of billets; precise control of rolling parameters to enhance the quality; heat treatment according to the need for normalizing, quenching, tempering and other treatments, to improve mechanical and corrosion-resistant properties to meet the stringent requirements.
5. Strict quality certification and inspection
The steel plate needs to be certified by Italian Classification Society, and various quality inspections are carried out during production, including chemical composition analysis, mechanical properties test, etc., to ensure that each steel plate meets the standard, which provides a reliable guarantee for the safety and quality of the ship.
