1 Scope This standard specifies the basic criteria for classifying steel products by the production process, shape, dimension and surface condition. This standard is applicable to the classification of steel products by the production process, shape, dimension and surface condition. 2 Classification The steel products are usually divided into four categories: a) liquid steel (see clause 3); b) ingots and semi-finished products (see clause 4); c) rolled finished products and end products (see clause 5); d) other products (see clause 6). 3 Liquid steel Steel in the liquid state ready for pouring and obtained from the direct melting of raw materials, which is used for ingot casting, continuous casting or cast steel castings. 4 Ingots and semi-finished products 4.1 Ingots Products obtained by pouring liquid steel into moulds of a shape appropriate. The shape of ingot moulds shall be similar to that of products processed by hot rolling or forging. The ingots used for the profile to be rolled may have a cross section that is square, rectangular (of width up to twice the thickness), polygonal, round, oval, or shaped; The slab ingots used for the plate to be rolled shall have a rectangular cross section, with a width twice the thickness or over. For the needs of further processing, the following treatments may also be conducted without changing the original classification of ingots: a) cleaning all surface defects with grinding tools or spray guns; b) cutting the head and tail or cutting to a length convenient for further processing; c) cutting after surface cleaning. 4.2 Semi-finished product It refers to the product obtained by rolling or forging steel ingots, or by continuous casting. Semi-finished products are usually used for further rolling or forging into finished products. The cross sections may be of various shapes (see 4.2.1~4.2.8); the cross-sectional dimensions are constant along the length with wider tolerances than those of the corresponding flat or long products and side corners more or less rounded. The side surfaces of semi-finished products are allowed to be slightly convex or concave, retaining rolling, forging, or continuous casting marks and may be partly or totally dressed, e.g. by cutting, flame melting, or grinding.
