What is Hot Rolled Steel Plate SS400?

Hot rolled steel plate SS400 is a very common type of steel in the construction and manufacturing industries. SS400 is a Japanese industrial standard for structural steel. It's widely used because of its good mechanical properties and relatively low cost. The "hot rolled" part means that the steel plate is produced by heating the steel above its recrystallization temperature and then rolling it into the desired thickness. This process gives the steel plate certain characteristics. For example, it usually has a rougher surface compared to cold - rolled steel, but it can be made in larger thicknesses more easily.

Applications of Hot Rolled Steel Plate SS400

One of the main applications of hot rolled steel plate SS400 is in building construction. It can be used to make columns, beams, and other structural components. In factories, it is often used to fabricate large - scale machinery frames. For example, in a car manufacturing factory, SS400 hot rolled steel plates might be used to build the frames for heavy - duty machinery used in the production line. It is also suitable for making general - purpose containers, like storage tanks for water or other non - corrosive substances. Another application is in the shipbuilding industry, where it can be used for the hull and other parts of the ship.

Quality and Specifications of SS400

The quality of SS400 hot rolled steel plate is determined by several factors. The strength is an important aspect. Generally, it has a yield strength of around 235 MPa, which means it can withstand a certain amount of force before it starts to deform permanently. The elongation rate is also a key specification. This indicates how much the steel can be stretched before it breaks. In terms of thickness, SS400 hot rolled steel plates can range from a few millimeters to tens of millimeters, depending on the specific requirements of the application. The width and length of the plates can also be customized according to different manufacturing needs.

Question 1: Where can we find hot rolled steel plate SS400?

We can find hot rolled steel plate SS400 in many places. In construction sites, it is often used for building structures, so it can be found there. In manufacturing factories, especially those involved in heavy machinery production or large - scale fabrication, SS400 hot rolled steel plates are commonly used. Also, in steel product warehouses or steel mills where they are produced and stored.

Question 2: How is hot rolled steel plate SS400 different from other steels?

Hot rolled steel plate SS400 is different from other steels in several ways. Firstly, its strength and elongation characteristics are specific to its standard. For example, compared to some high - strength steels, its yield strength of around 235 MPa is relatively lower. Secondly, the production process of hot rolling gives it a different surface finish and microstructure compared to cold - rolled steels. And in terms of applications, while some steels are designed for specialized applications like aerospace or high - temperature environments, SS400 is mainly used in general construction, manufacturing, and some industrial applications.
