Special Grade Steel Plate

Special Grade Steel Plate

Leong Jin sells a wide range of special grade steel plates for a variety of industries in Thailand. Let's get to know hot rolled steel first.

Hot Rolled Steel

Hot rolled steel is a downstream steel industry that is obtained by passing flat steel bars (slabs) through The hot rolling process reduces the size at a temperature of about 1,100 – 1,250 degrees Celsius. With large ironing balls It looks like kneading dough, but the slab must be heated to a high temperature until it is in a plastic state.

Hot-rolled steel can be divided into two major groups: hot-rolled steel coils that are easy to store and easy to transport and hot-rolled steel coils that are rolled according to customer sizes and specifications. There are many types and grades of hot-rolled steel, depending on their chemical composition. The common types and grades of hot rolled steel are:

  • Carbon steel sheet: It is a basic type of hot rolled steel and is widely used. It has low carbon content (usually less than 0.3%) and is suitable for general processing and processing. Carbon steel plates can be further classified into ordinary carbon steel, which does not contain any other alloying elements, and low-dilution steels, which contain small amounts of other elements, such as manganese, silicon, copper, etc. Common grades of carbon steel plates include ASTM A36, SS400,ASTM A1011, ASTM A283, ASTM A570, ASTM A572, ASTM A573, etc.
  • Structural steel plate: also known as High tensile steel. It is a type of hot-rolled steel sheet designed for structural applications such as buildings, bridges, boats, sluices, etc. Structural steel plates can be further divided into mild steel, which has low carbon content and good toughness, and high-strength steel, which has high carbon content and high hardness. Common grades of structural steel plates include ASTM A36, SS400ASTM A572, ASTM A573, ASTM A588, ASTM A709, JIS G3101, JIS G3106, EN 10025, EN 10028, ABS EH36, S355J2N, Cor-Ten A, Cor-Ten B etc
  • High Strength Low Alloy Steel Plate (HSLA): Also known as Ultra-high tensile steel It is a type of steel plate, which has high strength and is better formed than ordinary carbon steel plate. It is the result of the addition of small amounts of rare earth alloys such as niobium, vanadium, titanium, etc., or by special heating of steel plates such as the TMCP process, or it may be the Quenched and Tempered process. HSLA steel plates are used for applications that require high strength. Good weld ability, heat resistance to a certain extent, and corrosion resistance. Common grades of HSLA steel plates include ASTM A656, ASTM A709, ASTM A1018, ASTM A572, ASTM A514, Perform700, JFE-Hiten780LELiftHi700 etc
  • Pressure vessel and boiler steel sheet: Also known as Pressure and heat resistant steel it is a type of hot rolled steel used to make pressure vessels, boilers, and other equipment that operates under high pressure and temperature. High strength It has good toughness and excellent resistance to heat and corrosion. Steel plates, pressure vessels and boilers can be divided into carbon steel. It depends on the chemical composition and properties of the steel plate. Common grades of boiler pressure vessels and steel plates include ASTM A285, ASTM A387, ASTM A516, ASTM A537, ASTM A662, ASTM A738, JIS G3115, JIS G3118, EN 10028, ASME SA516-70, 16Mo3 etc
  • Wear Resistant Steel Plate: Also known as Wear resistant steel It is a type of hot-rolled steel plate that is hard and wear-resistant. The friction and high impact are for applications involving abrasion, bumping, or sliding, such as mining, construction, and material crushes sub machinery. Wear-resistant steel plates are usually produced by adding alloyed elements such as chromium, nickel, molybdenum, boron, etc., or by special heat treatment on steel plates. Common grades of wear resistant steel plates include ASTM A514, ASTM A517, ASTM A128, JIS G4051, JIS G4052, EN 10083, Perdur400, Perdur450, Perdur500, กลุ่มเหล็ก EVERHARD จาก JFE เช่นเกรด JFE-EH-C400, JFE-EH-C450, JFE-EH-C500, CREUSABRO steel group from INDUSTEEL ArcelorMittal such as CreusabroM, Creusabro4800, Creusabro8000, WearTuf, etc.

The special grades of steel sheet that Leong Jin stocks and sells include the following grades ABS EH36, S355J2N, Cor-Ten A, Cor-Ten B, Perform700, JFE-Hiten780LE, LiftHi700, ASME SA516-70, 16Mo3, Perdur400, Perdur450, Perdur500, EVERHARD, JFE-EH-C400, JFE-EH-C450, JFE-EH-C500, CreusabroM, Creusabro4800, Creusabro8000, WearTuf
