What is SS400 Steel Plate?
SS400 is a commonly used steel plate specification in the construction and manufacturing industries. It is a Japanese industrial standard for hot - rolled carbon steel plates, sheets, and strips. The "SS" stands for "structural steel," and "400" indicates the minimum yield strength of 400 megapascals (MPa) in its original state.
SS400 steel plates are known for their good ductility, weldability, and formability. They are often used in building structures such as bridges, buildings, and towers. For example, in the construction of a simple warehouse, SS400 steel plates might be used for the framework and roofing support.
Chemical Composition of SS400 Steel Plate
The chemical composition of SS400 steel plate mainly includes elements like carbon (C), silicon (Si), manganese (Mn), phosphorus (P), and sulfur (S). The carbon content is typically around 0.25% maximum. Silicon is present in a small amount, usually about 0.15 - 0.35%. Manganese content is around 0.60 - 1.60%. Phosphorus and sulfur contents are kept low, with phosphorus not exceeding 0.050% and sulfur not exceeding 0.050% as well. These elements contribute to the overall properties of the steel plate, such as strength and toughness.
Mechanical Properties of SS400 Steel Plate
As mentioned before, the minimum yield strength of SS400 steel plate is 400 MPa. The tensile strength is usually in the range of 490 - 610 MPa. The elongation is relatively good, which allows the steel plate to be bent and formed without cracking easily. For instance, when fabricating a curved beam for a bridge structure, the elongation property of SS400 ensures that it can be shaped properly.
Dimensions and Tolerances of SS400 Steel Plate
SS400 steel plates come in various thicknesses, widths, and lengths. Thickness can range from a few millimeters to several centimeters. The width can be several meters, and the length can be customized according to the specific requirements of the project. However, there are certain tolerances for these dimensions. For example, the thickness tolerance might be within plus or minus a certain percentage to ensure the quality and usability of the steel plate in construction.
Applications of SS400 Steel Plate
One of the major applications of SS400 steel plate is in the construction of high - rise buildings. The strong and durable nature of SS400 makes it suitable for bearing the heavy loads of the building structure. It is also used in the manufacturing of machinery parts, such as the base plates of large industrial machines. In the automotive industry, SS400 can be used for some non - critical components due to its cost - effectiveness and reasonable strength properties.
