steel bars and wire rods

Both steel bars and wire rods are rolled from reheated billets. CSCsupplies bars in two forms, namely straight bars and bars in coils, with the available nominal diameters from 5.5mm to 13mm for straight bars and from 14mm to 55mm for bars in coils.The rods are in a coil form only, with the available nominal diameters from 5.5mm to 13mm.The total annual production for both is around 1.77 million tons, of which the product assortmentsare 35% for low carbon steel, 18% for medium high carbon steel, 26% for cold heading steel, and 21% for low alloy steel. By the application of different processing techniques, steel bars and wire rods can be used for manufacturing general structures, machine structures, hard wires, and weld electrodes, and so on; they are also ideal materials for products which demand cold heading processing and hot forging processing.To meet the requirements of automated production and theupgrade of product quality for CSCs downstream customers, CSC has developed spheroidized products that are suitable for direct cold heading use.Theavailable products are SCM435 for automobile bolts, 50BV30 for hand tools, S2 for air-driven screwdriver heads, 36CrNiMo4 for air-driven sockets, and SNCM439 for cold forging chisels.CH1A and CH1T, extra low carbon cold heading steel with excellent cold heading and deep drawing quality, are suitable for the production of rivets and speaker tips. AISI 1018AK is a product with good internal cleanness and cold heading quality.NLP33K (for non-lead patented heat treatment steel) is a product with good quench strength and the feature of being able to be flattened easily. Both AISI 1018AK and NLP33K have helped to build Taiwan to become the kingdom for the production of tapping screws and umbrellas in the world.NLP77B and NLP82B are both materials for non-lead patented pre-reinforcing steel strand wires.AWS-EM12K and EH14 are materials for automatic submerged arc welding wires for steel structures, and SXXC S1 for resulfurized free cutting steel.All of the aforementioned products have been successfully developed to meet the demands of the downstream users, and they have all contributed a great deal to the upgrade of the industry in Taiwan.
