SS400 is a low carbon steel with no specified carbon content. According to its mechanical properties, it is similar to A588 grade A high strength steel ASTM A36, which is widely used in engineering and industrial applications. The cost of JIS SS400 steel angle steel structure is low, and it has good performance in major projects. SS400 angle steel description:Item: SS400 angle steel.

The strengthening mechanisms in metals mainly include solid solution strengthening, dislocation strengthening, fine grain strengthening, and second phase (precipitation and dispersion) strengthening. Alloying elements have the most significant strengthening effect on steel in the quenched and tempered state, because it makes full use of all four strengthening mechanisms. Martensite is formed during quenching, and carbides are precipitated during tempering, resulting in a strong second phase strengthening and greatly improving toughness. Therefore, obtaining martensite and tempering it is the most economical and effective comprehensive strengthening method for A588 grade A high strength steel.
