Commonly used steel plates and their classification

Common Steel Plate and Its Classification

Steel plates are an essential structural material for industrial and building purposes. The most common steel plate materials are carbon steel, High Strength Low Alloy (HSLA) steel, alloy steel, and tool steel, which all have various grades and sizes.

Carbon Steel Plate

Carbon steel plate is one of the most commonly used materials due to its affordability. It is liked in applications such as cookingware, furnaces, boilers, fuel cells and bridges. The most common grades are A36, A1011 and A283.

High Strength Low Alloy (HSLA) Steel Plate

These steel plates are crafted with a combination of carbon and other alloying elements. When compared to conventional steel, HSLA steel offers an increased strength to weight ratio, better formability and increased corrosion resistance. The most common grades are A572 and A656.

Alloy Steel Plate

Alloy steel combines the best attributes of these two materials to create a superior steel alloy. These steel plates are designed for high-performance applications such as pressure vessels, boilers and pipelines. The most common grades are A387 and A514.

Tool Steel Plate

Tool steel plates are crafted with a variety of elements to produce a steel that is suitable for a targeting application. The primary elements used in tool steel include chromium, nickel, molybdenum and tungsten. Tool steel is often heat treated and comes in many grades such as O-1, A-2 and D-2.

These are the most common types of steel plates that are used in a variety of applications. When choosing a steel plate, it is important to remember the specific grades and types to ensure it meets the intended purpose.

Carbon steel is an economical option and is favored in applications such as cookware, furnace parts, and bridges. High Strength Low Alloy (HSLA) steel is also an economical option and is favored for its increased strength to weight ratio, formability and corrosion resistance.

Alloy steel combines the best elements from carbon and other alloying elements to create a superior steel alloy that is ideal for use in applications such as pressure vessels, boilers and pipelines. Tool steel is designed for specific applications and is often heat treated to meet specific requirements.

Regardless of the type of steel plate chosen, it is important to make sure it is of the right grade, thickness and size to meet the specific purpose. Further, ensuring the steel plate meets all safety requirements is also essential. The right selection of the right steel plate is an essential step for any industrial or construction project.

Steel plate refers to rolled steel plate, which is a flat or roughly flat shape after being rolled, with a thickness of 4-240 mm, a width of 16-3000 mm and a length of 500-12000 mm.

Steel plates are widely used in mechanical manufacturing and engineering structures, such as construction and bridge building, shipbuilding, pressure vessels and boilers, oil storage tanks, etc. The steel plates are divided into ordinary steel plates and high-quality steel plates according to different grades and characteristics. Common steel plates include carbon structural steel, low alloy high strength structural steel, low temperature pressure vessels and boiler steels, and special steel plates for ships.

1. Carbon structural steel: Generally, the yield strength is not more than 250MPa. It is mainly used for bridge beams, buildings, ships, vehicles, etc.

2. Low alloy high strength structural steel: Generally, the yield strength is more than 355MPa. It is used to manufacture various engineering structures such as factory buildings, bridges, towers, vehicles, ships, etc.

3. Low temperature pressure vessel and boiler steel: Its characteristics are good plasticity in cold state and good welding performance. It is mainly used to manufacture pressure vessels, boilers and pipes for low temperature working environment.

4. Specialized steel plate for ships: Used for manufacturing ships and off
