This Standard was drafted as per the rules specified in GB/T 1.1-2009. This Standard replaced GB/T 6653-2008 Steel Plates and Strips for Welded Gas Cylinders. Compared with GB/T 6653-2008, this Standard has the major technical
changes as follows. --- Modify the requirements for chemical compositions; --- Modify the requirements for impact performance; --- Modify the requirements for non-metallic inclusions; --- Modify the requirements for surface quality.
This Standard was proposed by China Iron and Steel Industry Association.
This Standard shall be under the jurisdiction of National Technical Committee for
Standardization of Steel (SAC/TC 183).
Drafting organizations of this Standard. Angang Steel Company Limited, China
Metallurgical Information and Standardization Institute, Shougang Corporation, and
Wuhan Iron and Steel (Group) Corporation.
Chief drafting staffs of this Standard. Guan Jichun, Pu Zhimin, Zhang Weixu, Shi Li,
Liu Meihong, Wu Chaohui, and Chen Xiaohong.
The historical editions replaced by this Standard are as follows. --- GB 6653-1986, GB 6653-1994, GB/T 6653-2008.
1 Scope
This Standard specifies the dimension, shape, weight and permissible deviation, technical requirements, test methods, inspection rules, package, mark and quality certificate of steel plates and strips for welded gas cylinders.
This Standard is applicable to the hot-rolled steel plates and strips with thickness of 2.0mm~14.0mm, and cold-rolled steel plates and strips with thickness of 1.5mm~4.0mm used for the welded gas cylinder.

3 Expression Method of Grade
The grade of steel consists of two parts, namely, the initial of Chinese Pinyin “welded
cylinder” of “HP”, and lower limit of lower yield strength.
Example. HP295, thereof.
HP - the initial of Chinese Pinyin “welded cylinder”;
295 – the lower limit of lower yield strength of steel, in MPa.
