Slabs
A slab is a rectangular solid with a greater width than thickness, typically exceeding 150 mm. It can be processed into plates and coils through hot-rolling, followed by cold-rolling, to achieve marketable forms.
Blooms
Blooms, as semi-finished stainless steel products, are created using smaller mould sizes. They feature a square or rectangular cross-section with a thickness of approximately 120 mm or more; their width is proportional to the thickness.
Hot-rolled Coil
Hot-rolling involves deforming the slab or bloom at elevated temperatures (900°C to 1200°C), ensuring uniformity and enabling significant thickness reductions up to 98%. The resulting long and thin sheets are then formed into coils, which are then allowed to cool. These are known as hot-rolled coils.
Cold-rolled Coil
Cold-rolling produces smooth sheets and strips with precise dimensions and improved surface finishes. They are available in various conditions (skinrolled, quarter-hard, half-hard and fullhard) based on the level of deformation and strain hardening. These thin sheets are then coiled into cold-rolled coils.
Plates
Plates are produced by continuously casting slabs, which are then hot rolled after undergoing annealing and pickling. Alternatively, plates can be created by cutting desired lengths from hot rolled annealed pickled coils.
