EQ70 shipbuilding steel plate,EQ70 steel chemical

Posted:12/8/2014 1:38:50 AM EQ70 shipbuilding steel plate is a kind of extra high strength shipbuilding steel, it is mainly used to built hull of vessels, ship body construction and oil off shore platform.. EQ70 shipbuilding steel plate specification:Length:6000mm-12500mm, Thickness:4mm-80mm, Wide:1500mm-4500mm Effect of adding yttrium on precipitation behaviors of Jan 01, 2020 · In the E690 liquid steel, the activity coefficient is related to the temperature and interaction coefficient of various elements in the liquid steel. However, E690 offshore platform steel belongs to high-strength low alloy steels, the mass fraction of each solute element tends to 0, and the mass fraction of the solvent iron approaches 1.

Effect of adding yttrium on precipitation behaviors of

Oct 01, 2020 · The mechanism of inclusions precipitation of the E690 offshore platform steel, with and without addition of yttrium, was studied using the thermodynamic calculation method. The results show that in the E690 steel in the absence of yttrium, the MnS inclusions were precipitated in the liquid phase at the solidification front. By adding the yttrium, MnS inclusions were replaced by spindle and Effect of cathodic potentials on the SCC behavior of E690 Aug 26, 2015 · E690 steel, as a type of newly-developed high-strength bainitic steel, presents great potential in offshore platforms in the near future because of its comprehensive mechanical properties. However, the resistance to corrosion and SCC of E690 steel still needs to be investigated.

Chloride and sulphide anions were found to diffuse across the rust layer following the evaporation of seawater splashed on the steel's surface.

Influence of Rust Permeability on Corrosion of E690 Steel

May 16, 2018 · So in industrial environment, rust layer of E690 steel performs an uneven electric field, which means that it also provides an uneven cation-selective property (Ref 21, 27). On the contrary, rust layer of E690 steel in non-industrial environment performs a good cation-selective property. NV E690 and DNV Grade E690 steel plate Supplier - Steel Feb 04, 2019 · NV E690 is applied to extra high strength steels, which is defined as steel with specified min yield stress of 420Mpa. The max yield is 690Mpa in NV E690. NV E690 steel grade shall be killed and find grain treated. Steel grade of strength levels up to and including 500Mpa should be supplied in Normalized, TM or QT condition.
