Particularities of production of goods |
Stripes on the other 14-1-3226-81 are supplied in heat-treated (Normalizing + Tempering), no oiling, etched, without cropping the side edges, without editing and without Stripping of surface defects. The maximum depth of defects shall not withdraw the strip beyond the minimum thickness. The consumer makes no claim to the appearance on the surface of the bands of spots of rust (corrosion). The type and mode of heat treatment is set by the supplier. The steel shall withstand the bend test at room temperature at an angle of 180° on a mandrel of diameter equal to two thickness of the steel strip. |
