Foreword
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.
