ġ ġ1. Brief Introduction ġ China Steel Corporation炷CSC炸was established in December 1971 and started its production in December 1977. After four consecutive stages of expansion, the annual production capacity of crude steel has reached 11.5 million metric tons. The major of products are include steel plates, steel bars, wire rods, hot-rolled coils, cold-rolled coils, coated coils, electrical steel coils, and electro-galvanized coils. All of these products are widely used in various downstream manufacturing industry enhancing competitiveness and forming a mutual beneficial interdependence between the CSC and customers. And CSC proved it to be a reliable and innovated supplier of steel products. The accreditation certificate of ISO 9001, ISO/TS 16949,IECQ,ELV,Taiwan Accrediation Foundation (TAF) and JIS mark approvals were obtained to demonstrate CSC's commitment to keep progressing in quality management system. Providing cost-effective and superior quality of products and services to diversity of satisfied customer is the original mission of CSC. The company has therefore put a great deal of effort in expanding and modernizing its facilities, and continually improving the products quality and developing new products as well to help customers to create more value-added products. The newly developed steel plate products such as ASTM A841 GR.B CL. 2 TMCP, JIS G3101 SS400 (Laser cut plate), CSC LYS100, CSC PZ30H, CNS 13812 SN490YB/YC, CSC PZ590T, CSC PH490TB, CSC SM570M and ASTM A516 HIC were introduced to meet the stringent market demands.

Remarks烉1. When the content of soluble aluminum is not less than 0.015%, the minimum required silicon content does not apply. 2. For Grade A, rimmed steel sections may be accepted up to and including 12.5 mm(0.5 in). 3. A maximum carbon content of 0.23% is acceptable for Grade A sections. 4. For Gr.B steel of cold flanging quality or when fully killed, the lower limit of manganese may be reduced to 0.60%. 5. Gr.D hull steel which is normalized, thermo-mechanical control processed or control rolled is to be marked AB/DN. 6. The contents of nickel, chromium, molybdenum and copper are to be determined and reported. When the amount does not exceed 0.02%, these elements may be reported asʀ0.02%. 7. For Grade A sections, the upper limit of tensile strength may be 550 N/mm2(56 kgf/ mm2炻80 ksi).

Remarks烉1. For SB450 of over 25mm in thickness, the content of C may be designated to be within 0.30%, and that of Mn may be within 1.00%. 2. For tension test pieces, No.1A test piece shall be used for the steel plates of 50mm or under in thickness and No.10 test piece for that over 50mm. However, for the steel plates over 40mm in thickness, No.10 test piece may be used. 3. The elongation of No.1A test piece cut off from the steel plate under 8mm in thickness shall be the values in the above Table reduced by 1% for every decrease of 1mm of thickness or its fraction. 4. The elongation of No.10 test piece cut off from the steel plate over 90mm in thickness shall be the values in the above Table reduced by 0.5% for every increase of 12.5mm of thickness or its fraction. However, the reduction shall be limited to 3%. 5. When the elongation of No.1A test piece cut off from SB450M and SB480M steel plates of over 6 mm to and excluding 20 mm in thickness is more than the value specified in the above Table subtracted by 3, the test piece shall be accepted despite the above specification provided that the value of elongation in the gage length of 50 mm including the broken part is 25% or over.

Remarks烉 1. The letter symbol ‘W’ denotes that the plates are usually used in the delivered condition or chemically treated against rusting, while ‘P’ denotes that they are usually used after coated. 2 .The elements effective for the atmospheric corrosion resistance, such as Mo,Nb,Ti,V and Zr may be added to any grade of plates, provided that the total content of these elements does not exceed 0.15%. 3. Pertaining to the charpy absorbed energy, the value higher than those shown in the above table may be agreed upon by the parties concerned. 4. Impact test is applied only to the plates exceeding 12.0mm in thickness.
