Square steel is solid bar rolled or processed into square section.
Hot rolled square steel refers to steel rolled or processed into square sections. Square steel can be divided into hot rolling and cold rolling; The side length of hot-rolled square steel is 5-250mm, and the side length of cold drawn square steel is 3-100mm.
Cold drawn square steel refers to cold drawn steel forged in square shape. Cold drawn steel is to forcibly stretch the steel bar under normal temperature with a tensile stress exceeding the yield point strength of the original steel bar, so as to produce plastic deformation of the steel bar, so as to improve the yield point strength of the steel bar and save steel.
Cold drawn steel uses cold extrusion technology to pull out all kinds of round steel, square steel, flat steel, hexagonal steel and other special-shaped steel with high precision and smooth surface through accurate molds.
The specification of square steel is expressed in millimeters of side length. Generally, the specification of square steel is 5mm × 5mm~60 mm× 60mm.
Stainless steel square steel is mainly used to manufacture various structural parts and mechanical parts, and can also be used to roll billets of other small steels, such as rolling railway axles and spikes.
