Foreword
This Standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This Standard incorporates and revises GB 912-2008, Hot-rolled Sheets and Strips of
Carbon Structural Steels and High Strength Low Alloy Structural Steels, and GB/T
3274-2007, Hot-rolled Plates and Strips of Carbon Structural Steels and High Strength
Low Alloy Structural Steels.
Compared with GB 912-2008, Hot-rolled Sheets and Strips of Carbon Structural Steels
and High Strength Low Alloy Structural Steels, and GB/T 3274-2007, Hot-rolled Plates
and Strips of Carbon Structural Steels and High Strength Low Alloy Structural Steels,
the main technical changes of this Standard are as follows.
-- it changes the delivery length of steel strips with a defect into not more than 6%
of the total length of each roll of steel strip (see 5.6.4);
-- it adds intrinsic quality requirements (see 5.7); and
-- it extends inspection lot weight and changes into lot grouping by furnace (see 7.2).
This Standard was proposed by China Iron and Steel Industry Association.
This Standard shall be under the jurisdiction of China National Standardization
Technical Committee on Steels (SAC/TC 183).
The drafting organizations of this Standard. An Steel Co., Ltd., Chongqing Iron & Steel
(Group) Co., Ltd., Shougang Group Co., Ltd., China Metallurgical Information
Standardization Institute, HBIS Co., Ltd. Tangshan Branch, Ma Steel (Group) Holding
Co., Ltd., Fujian Sangang Group Co., Ltd. and Wuhan Iron and Steel (Group) Co., Ltd.
