Steel SS400 and SPHC are both types of steel commonly used in industrial applications, but they have some differences.
Steel SS400 is a structural grade steel that has a minimum yield strength of 235 MPa and a tensile strength of 400-510 MPa. It is primarily used for general structural purposes, such as buildings and bridges.
On the other hand, steel SPHC is a commercial quality hot-rolled steel with a maximum thickness of 2.4 mm. It has a lower carbon content compared to steel SS400, which makes it easier to form and weld. SPHC steel is often used in the manufacture of pipes, tubes, and other components in the automotive industry.
In terms of chemical composition, steel SS400 contains more carbon, silicon, and manganese compared to steel SPHC. Additionally, SS400 steel has better mechanical properties than SPHC steel due to its higher tensile strength and yield strength.
Overall, the choice between steel SS400 and SPHC depends on the specific application requirements, as well as factors such as cost and availability.
