Abstract

Disclosed is a method for manufacturing a 5Ni steel plate with a low remanence and an excellent surface quality to be used in a ship. The process flow thereof comprises: converter smelting→LF refining→RH high vacuum degassing→treatment with Ca→continuous casting→a slow cooling treatment to the slab→cleaning the surface of the slab→heating→rolling→quenching twice→tempering. The constituents comprise a low content of carbon, a low content of silicon, and 5% Ni, with V and Nb being added thereto, which improves the hardenability, improves the toughness at a low temperature, and improves the starting temperature of non-recrystallization of austenite. The steel plate can be subjected to high-temperature rolling and high-temperature quenching so as to significantly improve the shape of the plate, thus being applicable to the production of thin products.
