Ship Sheet Grades

Ship Sheet Grades

Ship sheet metal and other steel materials are among the materials used in shipbuilding. ship sheets is coming. The entire construction of a ship is made of steel. Steel is the most important raw material for shipbuilders. All parts of the ships made of steel, from the spine to the outer coating, are made of ship steel.

Shipbuilders generally prefer st 37 quality or st52 quality steel in the interior of the ship, which is called the backbone of the ship. Since these parts do not meet with sea water, it is not obligatory to use ship sheet metal here. Ship sheets are very close to commercial grade steels in chemical composition. A grade Ship plate When we compare the chemical components of the St 37 quality steel sheet in chemical components, the carbon ratio in the chemical composition of the A grade ship sheet is around 0.21, and the manganese value is higher in ship sheet metal than in commercial grade sheet metal.

As you can see in the table below, A grade ship sheet has chemical components.

As seen in the chemical component table of ship sheets, the main qualities are defined as A GRADE, B GRADE, C GRADE, D GRADE and E GRADE. When we look at the chemical structure of ship sheets, the difference in manganese value is striking. We know that the oxidation times of ship sheets differ from commercial quality sheets in terms of structure, and that their oxidation times are longer than st 37 quality sheets.

One of the only reasons for shipbuilding shipyards to use ship plate is the durability period. Ship construction steels are subjected to surface cleaning and painting before ship assembly. This is pissing ship sheet It is also called sandblasting painting. Steel balls are used to ensure surface cleaning and smoothness in sheet metal sandblasting painting processes, and after surface cleaning with steel balls, epoxy paint, which is called primer paint, is applied.

After the sandblasting and painting processes, the life of the steel material is extended. What is meant by prolonging the life of the steel is the slowing of the oxidation process. Steel does not change in strength. Another method of prolonging the life of steel is galvanizing. However, since the galvanizing method is compared to the cost of sandblasting painting, shipbuilders, that is, shipyard owners, prefer the sandblasting painting process because there is a very serious difference.

In addition, ship sheet metal grades are named differently according to European steel standards.

A class Ship Plate Thickness 5-60mm Width 1000-2500mm Length 3000-12000mm Package Standard export seaworthy package, suitable for all kinds of shipping or as required.

Graduated ship sheet Its plate is a flat steel bar or flat plate panel with a thickness of not more than 100mm and a width generally greater than 600mm. In practical applications, Containers and large equipment can use part about 5-20 mm thick. Better portability and good weldability, but poor corrosion resistance

a class Ship Plate Entry a class ship sheet Plate application range Class a Ship Plate is used for shipbuilding and oil platform purposes and has been approved by ABS, DNV, GL, BV, LR, NK, RINA and other classification societies. In addition, a quality Ship Plate can be used in the manufacture of the hull structure of the ship weighing less than 10000 tons. Chemical composition of a grade Ship Plate:

ASTM class A ship sheet plate is suitable for the steelmaking process. The nature of the work environment is challenging. Chemical composition is also a certain requirement. It must meet H2S resistance and performance requirements in low temperature, low pressure and high corrosion environments.

For thickness below 30mm, we mainly cut by laser cutting, for thickness above 30mm, we mainly cut by OXY cutting, flame cutting. For 200mm thick steel plate, the temperature is too high during flame cutting. Therefore, the cutting parts may break at the angle part of the steel plate. In this case, we can use pig iron to add more material to the broken pieces.

We expanded our production capacity and expanded the thickness and width range by increasing the number of sub-grades for each part of our product.

steel plate production line. The steel plate is thin enough to be rolled into large diameter welded pipes. Film is a process in which the steel plate is dipped in acid solution and then electroplated.

Continuous casting: The molten steel is poured into a rope about 20 meters long, which is quickly quenched to solidify it and lower its temperature to 200-300°C. The wire is guided by rollers and takes the form of a plate.

Ship Sheet Classification, Class Standard,

Shipbuilding steel plate refers to the hot rolled steel for the manufacture of ship structures produced in accordance with the requirements of the construction society. A ship, steel, etc., including steel order, scheduling, sales, ship plate, often used specifically.

ASTM A131 is the Standard Specification for Structural Steel for Ships. We offer higher strength shipbuilding steels with SA131 Grade A plate as standard. There are also higher strength shipbuilding steels such as AH36, DH36 and EH36.

A131 Grade DH32 marine steel plate is mainly used in the construction of ships sailing in low temperature oceans. A131 Grade DH32 should be made for heat treatment during TMCP or Normalized rolling and low temperature impact test below minus 20 degrees Celsius. A131 Grade DH32 steel plate should be subjected to low temperature impact test under minus 20 degrees Celsius.

These products are typically used for castings and forgings that require enhanced machinability, but use is not limited to such applications. Alloy 410S stainless steels are general-purpose martensitic stainless steels containing 11.5 percent chromium that provide good corrosion resistance properties.

Normalizing forms part of a heat treatment process that equalizes the steel's properties and creates a uniform ferrite and cementite grain size. It results in the material being more ductile, which allows for better shaping and bending. This is done by heating the steel above the upper critical temperature (austenitization temperature) and then cooling it to room temperature with still air as the medium.

Steel is everywhere in our lives. It is used to build bridges, hard hats, skyscrapers and thousands of other things we use every day. In fact, the strength and reliability of steel have made it a mainstay of the world economy for hundreds of years.
