Mild SS400 Hot Rolled Carbon Steel Plate

Ss400 is one of the most commonly used hot rolled general structural steel. We can regard Ss400 steel plate as carbon and low alloy steel Ss400 steel plate is one mainly of carbon and low alloy steel, SS400 steel plate would be used to built containers which can bear low temperature sea water.

As well as being available from stock all ss400 steel plate can be cut to size and shape according to your fabrication and design requirements. Our SS400 steel plate are sourced from the highest quality steel manufacturers in the world and, like all our suppliers, these manufacturers have been vetted and assessed by our procurement team.

Ss400 steel plate sheet is a kind of steel for general structure,and it is used in ship,house,bridge making and so on.This kind of steel plate sheet SS400 has some features,like its heat condition,excellent freezing,even structure with pressure resistance and its good mechanical properties.

This specification of SS400 steel plate covers carbon structural steel shapes, plates, and bars of structural quality for use in riveted, bolted, or welded construction of bridges and buildings, and for general structural purposes. Heat analysis shall be used to determine the required chemical composition for carbon, manganese, phosphorus, sulfur, silicon, and copper. Tensile strength, yield strength, and elongation shall be evaluated using tension test and must conform to the required tensile properties.

• Chemical Composition(max %) of SS400 Hot Rolled Carbon Steel Plate

  Carbon (C)	The content is ≤ 0.21%. It belongs to the category of low - carbon steel, endowing the steel with good weldability and cold - working properties.
  Silicon (Si)	The content is ≤ 0.30%, which can improve the strength and toughness of the steel.
  Manganese (Mn)	The content is ≤ 1.40%, helping to enhance the strength and other properties of the steel.
  Phosphorus (P) and Sulfur (S)	As impurity elements, their contents are both required to be ≤ 0.050% to improve the purity and performance of the steel.

• Mechanical Properties

  Tensile Strength	Generally, it ranges from 400MPa to 510MPa, enabling it to withstand significant tensile forces.
  Yield Strength	The yield strength varies with thickness. When the thickness ≤ 16mm, the yield strength ≥ 245MPa; When the thickness is between 16 - 100mm, the yield strength ≥ 235MPa; When the thickness > 100mm, the yield strength ≥ 205MPa.
  Elongation	Generally, it is ≥ 26%, maintaining good plasticity when subjected to tension.
  Impact Energy	≥ 27J, showing good impact resistance.

• Performance Characteristics

  Good Weldability	Carbon steel plate hot rolled can be connected and assembled through common welding methods such as arc welding and gas - shielded welding.
  Easy Machinability	SS400 hot rolled steel plates is easy to cut, bend, stamp, etc., meeting the requirements for the shape and size of steel in different fields.
  High Strength and Toughness	Hot rolled steel plate for shipbuilding has high strength and toughness, can resist fatigue, impact, and wear. After appropriate anti - corrosion treatment, it can also resist corrosion to a certain extent.

• Application Fields

  Construction Field	SS400 hot rolled steel plate is used for components such as beams, columns, stairs, and floor slabs in industrial plants, commercial buildings, and residential buildings. It is also widely used in steel structures and building walls.
  Bridge Engineering	JIS G3101 low carbon steel plate is suitable for manufacturing structures and components of bridges, such as beams, bridge decks, and piers.
  Machinery Manufacturing	Prime hot rolled steel plate is commonly used to manufacture mechanical parts and equipment such as light machinery, bearing supports, bearing blocks,  gears, connecting rods, and pins. It can also be used to manufacture key components such as gas turbines, turbine blades, diesel engine pistons, and generator rotors.
  Automotive Manufacturing	Hot rolled non alloy steel metal sheet low carbon steel plate can be used to manufacture automotive chassis, frames, and body parts.
  Shipbuilding	High quality hot rolled steel plate is used in the production of hull structures and some mechanical components.
  Petrochemical Industry	JIS hot rolled steel plate can be used to manufacture pressure vessels, pipelines, and other equipment.
