The weight of the ship plate can be set according to the weight required by the ship, so that neither the weight of the ship nor the speed of operation will be affected. The price of RINA grade D stern frame steel, medium and thick ship plates is determined according to the thickness and quality, which can be combined with the cost of shipbuilding to calculate the price, and then make a choice, so that it will not affect the cost of shipbuilding.
Iron and steel goods, including pig iron, ingots, all kinds of steel and so on. Therefore, logistics companies are required to load evenly and evenly in the process of transportation, prevent moisture and prevent corrosion. It is necessary to prevent the RINA grade D stern frame steel steel sheet from being mixed with water when transporting the steel; it is necessary to prevent the RINA grade D stern frame steel steel from being mixed with water when transporting the steel; it is necessary to prevent the steel from being mixed with water when transporting the steel; it is necessary to prevent the steel from being mixed with water when transporting the steel; it is necessary to prevent the steel from being mixed with water when loading the RINA grade D stern frame steel steel sheet on the truck Good luck.
After adding a small amount of niobium, vanadium and titanium to RINA grade D stern frame steel etc. steel, it is combined with the controlled rolling process to control the precipitation behavior of microalloying elements to achieve the purpose of improving the comprehensive properties of the steel, whether it is strength, toughness, ductile-brittle transition temperature, or Steel's process formability, welding performance, corrosion resistance and crack resistance have been significantly improved, while reducing production costs. Such steel products are widely used in oil and gas pipelines, vehicles, building structures, oil production platforms, pressure vessels, ship shells and many other fields.
Specification range of available steel RINA grade D stern frame steel: thickness ≤ 650mm, width ≤ 4500mm, length ≤ 18000mm. Larger specifications of steel plates are also available as required. Our steel plates RINA grade D stern frame steel can be supplied according to Chinese standard, American Standard AISI / ASME / ASTM, Japanese JIS, German standard DIN, French NF, British BS, European EN, international ISO and other standards. Heat treatment process: controlled rolling, normalizing, tempering, normalizing plus tempering, quenching and tempering, etc.
