Foreword
This Standard replaces GB/T 4226-1984 "Cold Finished Stainless Steel Bar".
Compared with the original standard, this Standard has the following major changes.
- ADD the requirements for "order contents", "classification and code" and
"smelting process";
- ADD the peeling and polishing delivery conditions for bright steel bar;
- MODIFY the requirements for dimension, shape and permissible deviation;
- DELETE the original chapter of "category and designation"; directly ADOPT the
designations specified in GB/T 1220-2007;
- REVISE "Mechanical property" TO agreed inspection items;
- ADD the macrostructure inspection items;
- ADD the agreed inspection items for "corrosion resistance";
- MODIFY the requirements for "surface quality".
This Standard is proposed by China Iron and Steel Association.
This Standard is under the jurisdiction of the National Technical Committee on Iron
and Steel of Standardization Administration of China.
Main drafting organizations of this Standard. Dongbei Special Steel Group Co., Ltd.,
Metallurgical Information and Standardization Institute, Changzhou Daping New
Stainless Steel Products Co., Ltd., Yongxing Special Stainless Steel Co., Ltd..

The previous edition of the standards replaced by this Standard is as.
- GB/T 4226-1984.
Cold Finished Stainless Steel Bar
1 Scope
This Standard specifies the order contents, classification and code, dimensions,
shape, weight and permissible deviation, technical requirements, test methods,
inspection rules, packing, marking and quality certificate for the cold finished stainless
steel bar (general term of round steel, square steel, hexagonal steel and flat steel,
hereinafter referred to as steel bar).
This Standard is applicable to the cold-rolled or cold-drawn round steel, square steel,
hexagonal steel, flat steel and bright round steel (peeling, burnishing and polishing)
whose dimensions (diameter, side length, distance or width of opposite side,
hereinafter referred to as dimension) are not greater than 100mm.
