In the field coated steel in particular, the joint venture company Wheeling-Nisshin, Inc. was established in partnership with Wheeling-Pittsburgh Steel Corporation in the United States in June 1984 to manufacture galvanized and aluminized steel sheet. Its first production line went into operation in 1988, and operations are proceeding smoothly. To meet the growing demand for coated steel sheet in the American market, in 1991 the company began construction of a second production line, which came online in 1993. At present, the company maintains a combined monthly production of 50,000 tons. Chang Fu Stainless Steel Center(Suzhou), a Nisshin Steel joint venture, aims to help meet China's increasing demand for stainless and high-tech steel. EUROPE ACERINOX,S.A.

Over the years, our objective has been to develop innovative products and technologies. In the coated steel segment, the opportunities have been many as demand has grown and applications broadened. The result has been an increasing variety of Nisshin products. To manufacture these products, we have developed innovative processing technologies. The gas wiping technique which we developed has achieved superior coating uniformity for zinc-coated sheet. Additional advancement have enhanced other properties such as corrosion resistance, paint adhesion, and formability. 7 Nisshin Steel Quality Products ■ Zinc-Coated Products at a Glance ■ 1.GALVANIZED STEEL SHEET Cross-sectional composition of galvanized steel sheet Zn(zinc) Superior workability Moonstar brand galvanized steel sheets have a minimum iron-zinc alloy layer. This insures that the coating will not peel under normal forming methods. Regular Spangle Fe(iron) Uniform coating thickness Moonstar brand galvanized steel sheets are manufactured by Nisshin Steel's unique gas wiping process which assures the formation of a uniform zinc coating over the steel surface. Many problems of the conventional process have been completely overcome, greatly improving the quality of the finished product. Minimized Spangle High corrosion resistance Excellent appearance Zinc coating prevents corrosion by sealing off the steel surface from corrosive environments. If the coating is accidentally scratched the surrounding zinc then acts as a sacrificial anode and "heals the wound". This is called "sacrificial protection." This sheet has a beautiful, smooth surface due to the complete suppression of spangles by a special treatment right after galvanization. Its excellent appearance is ideal for uses which require high corrosion resistance without painting. 2.GALVANNEALED STEEL SHEET Variety of coating thicknesses available Galvannealed sheet is an iron-zinc alloy suitable for painting. Several different coating thicknesses are available to suit individual applications. Cross-sectional composition of galvannealed steel sheet Zn+Fe (zinc-iron alloy) High corrosion resistance Galvannealed sheet is specially galvanized by our unique gas wiping process, which forms a uniform zinc coating. If scratches occur during one of the primary forming processes or during transit, the galvanic action will prevent rust from occuring. Fe(iron) Strong paint adhesion This sheet's coarse surface induces paint adhesion far better than other coated steel sheets. Economical There is no need for chemical treatment when applying paint. This means great savings in labor, materials,and time. A broad range of applications Galvannealed sheet is ideal for a broad range of applications from construction materials to electrical appliances.

Guide to Ordering 1.Specification Select the most suitable grade from this brochure according to the desired degree or method of forming to be employed and the intended final use. 2.Surface Treatment Select the most appropriate surface treatment from this brochure according to the desired method of treatment after forming and the conditions under which the final products will be used. 3.Coating Mass Specify the proper coating mass according to the desired corrosion resistance, the conditions of use of the final products, the forming method to be employed and other relevant factors. 4.Oiling The application of rust-preventive oil may be specified regardless of the surface treatment. It is recommended to specify oiling in order to protect against rusting in intermediate processes and against fingerprints, smearing or damage during handling, as well as for lubrication during the forming process. Oiling is necessary for zinc-coated steel sheets without surface treatment. 5.Coils Specify delivery in coils or cut lengths according to the conditions of cutting or forming. Coils offer a higher material yield and assist in the automation of forming operations; however, some detective portions might remain because they cannot be removed through inspection. 6.Edge Finishing Select either mill edge or slit edge according to the conditions of use. Nisshin Steel Quality Products 24 Precautions in Use 1.Unloading and Storage (1)If zinc-coated steel sheets become wet during unloading or storage, white rust will occur. Keep zinc-coated steel sheets fully protected from rain, dew and seawater. Storage where humidity is high or in a sulfur dioxide atmosphere should be avoided. Store in a clean, dry place. (2)Any damage to packing paper should be repaired. Abrasion spots (black spots) ■Very occasionally, black stains of film 1mm to 5mm in diameter appear at regular intervals on the surface of zinc-coated steel sheets in coils as well as cut lengths. Such stains cannot be wiped off even with benzene, ethyl alcohol, or any other solvent. These stains, usually called abrasion spots or black spots, do not form during manufacturing but are caused by sheet-to-sheet friction due to repeated vibration during transit. Although it is true that abrasion spots spoil the appearance of zinc-coated steel sheets, they present no practical problem in use apart from appearance. ■How do abrasion spots occur? Zinc-coated steel sheets in transit are subjected to repeated vibration of various degrees, which causes sheet-to-sheet slippage. The long duration of this repeated slippage causes extremely minute projections and indentations on the sheet surface to enlarge, resulting in the formation of black or abrasion spots. Thus, to prevent abrasion spots, special devices are needed to ensure that steel sheets in transit are not subjected to repeated vibration. 2.Forming (1)Use lubricating oils if zinc coating sticks to the surface of the roll in roll forming or to the die in press forming. (2)Some lubricating oils containing an extreme-pressure additive are corrosive to zinc. Before using a lubricating oil, confirm that it is not corrosive. If the use of corrosive oil is unavoidable, perform degreasing or other post-treatment immediately after forming. 3.Welding When resistance welding is employed, zinc will stick to the electrodes, requiring them to be cleaned or replaced as appropriate. 4.Painting In order to obtain good paint-to-sheet adhesion,the surface of zinc-coated steel sheets should be subjected to chemical or similar treatments prior to painting. 5.Fabricating Chips such as metal dust which occur in fabricating spoil the appearance of the products. Remove chips from the products carefully. 25 Nisshin Steel Quality Products ISO Certification 1.All the Company's Works Achieve ISO 9002 Certification ISO 9002 certification was obtained by all Nisshin Steel's works by 1997/98. In acquiring this certification, the company's quality management systems have acquired a global assurance "passport" for all of its products and production technologies. 2.All Zinc-coated Steel Sheet Produced under ISO 14001 Certification To further promote the principle of "continuously improving the company's environmental management system,"Nisshin Steel has been actively seeking ISO 14001 certification. By March 1998 five of Nisshin Steel's works attained certification for this international environmental management standard. The certified works include the Kure works which serves as our melting center and the Sakai and Ichikawa works which produce coated steel. Thus, all Nisshin Steel's zinc coated steel sheets are manufactured in the works with ISO 14001 certification. The Sakai Works, our first works obtaining the certification, uses a variety of manufacturing processes to create a range of products-principally different types of surface-treated steel sheets. Moreover, the works' proximity to populous urban areas as well as the Seto Inland Sea National Park requires it to have all the more stringent controls in place. Keenly aware of the importance of promoting environmental protection, the works established an environmental management system, which directly led to the achievement of ISO 14001 certification. ISO 14001 Certificate of Registration awarded to the company's Sakai Works.
