Cold-formed steel (CFS) is the common term for steel products shaped by cold-working processes carried out near room temperature, such as rolling, pressing, stamping, bending, etc. Stock bars and sheets of cold-rolled steel (CRS) are commonly used in all areas of manufacturing.
Cold-rolled sheets and strips come in various conditions: full-hard, half-hard, quarter-hard, and skin-rolled. Full-hard rolling reduces the thickness by 50%, while the others involve less of a reduction. Cold rolled steel is then annealed to induce ductility in the cold rolled steel which is simply known as a Cold Rolled and Close Annealed.
The company procures hot rolled steel and processes it into CR and further into GP and colour-coated coils. [ 2 ] Uttam Galva group also runs two more plants in India: Uttam Galva Metallics Limited and Uttam Value Steels Limited (previously known as Lloyds Steel Industries Limited) both at Wardha , Maharashtra .
In 1938, the company brought online a single 4-high reversing cold reducing mill with ancillary facilities (annealing and finishing). Over the next few years, modifications were made to the equipment the company would gain capacity to roll 108,000 net tons of hot rolled products and 60,000 net tons of cold rolled products per year.
Ironworks at Port Talbot. Abbey Steelworks was planned in 1947, but today is correctly termed Tata Steel Strip Products UK Port Talbot Works.It is believed to be named after the Cistercian Margam Abbey that used to be on the site – a small amount of the original building still stands (protected) within the site that survived the dissolution of the monasteries.
International Steels was founded by Amir Sultan Chinoy in 2007 as a joint-venture between International Industries Limited, Sumitomo Corporation, and JFE Steel. [6] [3] Its plant was commissioned in 2010 at a cost of $162 million and it had a capacity to produce 280,000 tons per annum of cold rolled coil from hot rolled coil, including 150,000 tons per annum of galvanized steel.

The acquisition would also include a coke-making facility and interests in three joint ventures that process flat-rolled steel products. [1] Severstal also announced at that time that it would sell a separate steel-making facility in Columbus, Mississippi to Steel Dynamics for $1.63 billion.

41xx steel is a family of SAE steel grades, as specified by the Society of Automotive Engineers (SAE). Alloying elements include chromium and molybdenum , and as a result these materials are often informally referred to as chromoly steel (common variant stylings include chrome-moly , cro-moly , CrMo , CRMO , CR-MOLY , and similar).
