SS400 SM400B Carbon Steel Beam

SS400 SM400B Carbon Steel Beam

SS400 according to material grade and name defined in the JIS G 3101 standard, The first S stands for "Steel", the second S stands for "Structure", and 400 for the lower limit tensile strength of 400 MPa. Ordinary structural steel with a tensile strength of 400 Mpa. This steel is the most widely used in JIS standard. SM400B is rolled steel for welding structure, M(Marine escape welding), 400 is also the lower limit tensile strength 400MPa, equivalent to the domestic Q235B.

What is SS400 Material?

SS400 material is structural grade steel designed specifically for construction, engineering, and other related applications. This material is known for its excellent strength-to-weight ratio, high flexibility, and corrosion resistance. It also has good weldability characteristics and can be easily machined into specific shapes with minimal effort.

What is Mild Steel?

Mild steel is carbon steel with low amounts of alloying elements like manganese or chromium added to enhance its properties. This material offers superior strength compared to other common types of carbon steel while still maintaining its ductility, making it ideal for construction projects where weight needs to be kept down without sacrificing strength or durability. Its corrosion resistance isn't as good as SS400 material but can be improved with proper coating or galvanization.

Comparing Both Materials

When deciding between SS400 material vs mild steel, it's important to consider the specific requirements of your project. In general, SS400 material offers superior corrosion resistance and weldability compared to mild steel but may not be as strong in certain applications. On the other hand, mild steel provides better strength than SS400 but may not have the same level of corrosion protection or weldability. Ultimately, you will need to weigh all the pros and cons before making a decision about which material is best for your project.
