Cold Formed Hollow Section Kloeckner Metals UK

Cold formed (Circular / Rectangular / Square) hollow sections are formed at ambient temperature and are produced in accordance with standard EN10219-1 Multi-purpose applications The material is suitable for use in multi-purpose applications of a non-critical nature and is produced from fully-killed steel critical to formability and weldability. Cold Rolled and Hot Rolled VS. Cold Formed and Hot FormedCold Rolled and Hot Rolled VS. Cold Formed and Hot Formed, The misconception. There is a large misconception in the market and across all industries in South Africa regarding the terms cold and hot rolled and cold and hot formed. The difference in the terms is simple yet confusing. Cold Rolled and Hot Rolled Products refers to the type of steel

Cold-formed Square Hollow Sections Harris (Steels) Ltd

Hot finished hollow sections are first cold rolled to a circular profile as above but are then heated to the steels normalising temperature of around 900°c+, the tubes are then passed through forming rolls individually and air cooled to further relieve material stresses. Comparative experimental study of hot-formed, hot-finished Dec 01, 2016 · The tested hot-formed and hot-finished hollow sections were of dimensions 180 mm × 180 mm × 12.5 mm, while the cold-formed hollow section was of dimensions 200 mm × 200 mm × 12.5 mm. Surface discontinuities including rolled-in scale and pitting, indentations and roll marks, scratches and grooves, spills and silvers, blisters, sand patches, cracks, shell, and seams were examined.
