This Standard modifies and adopts international standards ISO 3755.1991 "Cast Carbon Steels for General Engineering Purposes" and ISO 4S90.2003 "Steel Castings - General Technical Delivery Requirements". This Standard integrates, modifies and adopts ISO 3755.1991 and ISO 4990.2003.The differences of main technical contents are as follows. — Significant revision has been made to the structure, such as. Chapter 7 of ISO 3755.1991 has been revised; Table 1 permissible variation in chemical composition and Table 2 alternate material list in ISO 4990.2003 have been deleted. — Specification, sampling location and dimension of mechanical property test blocks in Annex B of ISO 4990.2003 have been revised. Comparison table between this Standard’s clauses and international standard’s clauses are given in Annex C for the convenient comparison. This Standard shall replace GB/T 11352-1989 "Carbon Steel Castings for General Engineering Purpose". Compared with GB/T 11352-1989, the following main technical contents are revised in this Standard. — Add the spectral analysis method for chemical composition analysis; — S and P controlling quantities of each designation are reduced; — Test blocks for mechanical property of attached castings and single-cast test block are listed for adoption. Annex A, B and C in this Standard are informative. This Standard was proposed by China Machinery Industry Federation. This Standard shall be under jurisdiction of the National Technical Committee of Standardization for Foundry Responsible drafting organization of this Standard. Shaoguan Foundry and Forging Group. Participating drafting organization of this Standard. Shanghai Zhongxing Jiqi Chang Co., Ltd. AND Shenyang Research Institute of Foundry. Chief drafting staffs of this Standard. Liu Qiping, Yu Zhengjiang, Yu Bo, Sun Shuqing and Ye Jianjun. The previous edition replaced by this Standard is. — GB/T 11352-1989. Carbon Steel Castings for General Engineering Purpose1 Scope

Designation of the carbon steel castings for general engineering purpose (hereafter abbreviated as castings) specified in GB/T 5613 comprises. ZG 200-400, ZG 230-450, ZG 270-500, ZG 310-570 and ZG 340-640.4 Technical requirements
Mechanical property shall be in accordance with the provisions of Table 2.If the purchaser has no requirement toward the shrinkage factor of cross-sectional area and impact ductility, the Supplier can choose one of them. Distortion of casting can be removed through straightening.5 Test methods
Tensile test shall be carried out according to the provisions of GB/T 228. Impact test shall be carried out according to the provisions of GB 229.6 Inspection rules
It is required to analyze chemical composition of casting according to melting furnace number or each batch; analysis result shall be in accordance with the provisions of Table 1. When results of mechanical test do not meet the requirements, and it is not caused by the reasons listed in 6.5.1.3, then supplier can conduct re-inspection. Results of test for mechanical property and chemical composition can be rounded off according to the rules of test methods or the provisions of GB/T 8170.7 Mark, packaging, transportation and storage
Casting shall be packed and treated with protective treatment after passing test. Cast surface protection, transportation and storage shall meet order agreement.8 Additional requirements
During inquiry and order, one or more items of the following additional requirements can be specified. The position and hardness range of metallic Brinell hardness test shall be determined by supplier and purchaser through negotiation. Brinell hardness test shall be carried out according to those specified in GB/T 231. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
