SS400 SM400A Steel Angle

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. SM400A belongs to the ordinary carbon structural steel plate in the hot rolled carbon steel plate, 400 represents the tensile strength of more than 400, SM is the name of the Japanese standard material, A represents the level, indicating that there is no impact. There's also SM400B, which stands for ambient shock. SM400C stands for normal temperature impact, SM400D stands for -20 degree impact, SM400E stands for -40 degree impact,

How Steel Channels are Made

A steel channel is a structure made of hot-rolled mild steel. The interior corners of steel channels have a specified radius. This provides the strength and rigidity they need to sustain steel angles and building projects. With the correct equipment and proportions, they're fairly simple to prepare. Steel channels are usually manufactured to ASTM 36 dimensional specifications.

Steel channels are usually subjected to extra inline fabrication after being hot-rolled. They are coated or galvanized after fabrication to make them corrosion-resistant. Steel channels can be cut, drilled, or machined according to given specifications. They can also be easily welded. The laser fusion technique is commonly used to create large channels.
