CHINA STEEL
SteelBar And WireRod Product
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
CSC’s 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.
