Q355 low alloy steel plate
Q355 low alloy steel plate is a new type of high strength, low alloy structural steel plate with good mechanical properties and corrosion resistance. It is composed of carbon, silicon, manganese, phosphorus, sulfur and other elements, and is made through a special heat treatment process. Q355 low alloy steel plate is widely used in construction, bridges, ships, machinery manufacturing and other fields. Its unique properties make it an ideal choice to replace traditional steel.
Composition and properties
The main components of Q355 low alloy steel plate are carbon, silicon, manganese, phosphorus and sulfur. Among them, the carbon content is low, which can improve the strength and hardness of the steel plate while maintaining good weldability and processability. The addition of silicon and manganese can enhance the corrosion resistance and stress corrosion resistance of steel plates. Lower levels of phosphorus and sulfur reduce steel plate brittleness and susceptibility to hot cracking.
Q355 low alloy steel plate has high yield strength and tensile strength, excellent plasticity and toughness, as well as good wear resistance and corrosion resistance. It also has good weldability and processability, and can meet the processing needs of various complex shapes.
Application fields
Q355 low alloy steel plate is widely used in many fields. In the construction industry, it is often used to make steel structures, bridges, stairs, roofs, etc. In the field of shipbuilding, Q355 steel plates are used to manufacture hulls, decks and other structural components. In the machinery manufacturing industry, it is often used to manufacture heavy machinery equipment and construction machinery.
Q355 low alloy steel plate is also widely used in the energy industry, automobile manufacturing, petrochemical industry, metallurgy and other fields. Its high strength and corrosion resistance make it ideal for use in a variety of harsh environments.

Our heavy-duty forging presses support open-die forging and deformation of large-section forgings, including discs, shafts, blocks, and custom components. This capability enables us to meet the demanding forming requirements of heavy industrial applications.
Heat treatment is a critical step in achieving the mechanical properties required for heavy-duty forgings. Our process capabilities meet the strength, toughness, and structural stability requirements for forged components used under demanding operating conditions.
We offer machining capabilities for large forged shafts and long cylindrical components, supporting both rough and finish machining. This capacity is suitable for stepped shafts, rotor shafts, rollers, and other heavy-duty forged shaft components.
Our machining facilities are capable of handling large ring-shaped forgings and circular parts that require precise turning, face machining, boring, and contour control. This capability is suitable for industrial ring blanks, heavy-duty circular parts, and machined ring forgings.
We offer machining solutions for heavy-duty cylindrical, hollow, and tubular forgings. This capability supports the machining of sleeves, cylinders, and other thick-walled forged components used in pressure vessels, rotating systems, and general industrial applications.
Quality control is integrated into our production process through the inspection and testing of forged and machined parts. Our capabilities help verify the dimensional accuracy, condition, and quality consistency of industrial forgings prior to delivery.
Finished forgings are properly protected and packaged to minimize the risk of damage during storage and transportation. Our packaging methods ensure the safe domestic delivery and export shipment of machined and high-value forged components.
