Scope

This Standard specifies the classification and code, ordering information,
dimension, shape, weight, allowable deviation, technical requirements, test
methods, inspection rules, packaging, marks and quality certificate of the hot-
rolled steel sheets and strips of higher yield strength with improved formability.
This Standard is applicable to the hot-rolled steel strips of higher yield strength
with good formability and the thickness of 1.0mm to 6.0mm, the steel sheets
produced by the crosscutting of steel strips, and the steel strips produced by rip
cutting (hereinafter referred to as “steel sheets and strips”).
