Foreword
This standard replaces GB/T 908-1987 "Forged round and square steel size, shape, weight and tolerance" and GB/T 16761-
1997 "forged steel size, shape, weight and tolerance."
This standard compared with the original standards, the main amendments are as follows.
--- Standard name was changed to "forged steel bars size, shape, weight and tolerance";
--- Bar diameter increased from 250mm to 400mm, square steel side length increased from 250mm to 400mm, and a corresponding increase in foot
Inch tolerance;
--- Canceled GB/T 908-1987 standard "tool steel and bearing steel size deviation should be consistent with the provisions of Table 2 Group 1";
--- Cancel the GB/T 16761-1997 standard "size deviation tool steel shall conform to the provisions of Table 2 1 group."
The standard proposed by China Iron and Steel Association.
This standard is under the jurisdiction of the National Steel Standardization Technical Committee.
This standard was drafted. Dongbei Special Steel Group Co., Ltd. (Fushun), Metallurgical Industry Information Standards Institute.
