Thickness
BPS-SB-2000C is supplied in standard thicknesses in accordance with the table below.
Finishes
Edges
Edges are slit and deburred.
Flatness
Maximum out-of-flatness across and along the steel belt is 0.30% of the nominal steel belt width.
Surfaces
Material is delivered white polished, free from oxide discoloration and with uniform colour and dust free.
Surface roughness
Maximum surface roughness values, cut-off 0.25 mm (.0098 inch), are shown in the table below.
Surface defects
A small number of surface defects, such as pits and roll marks, with a depth or height of up to 15 µm (400 µinch) maximum is allowed. The maximum scratch depth allowed is 22.0 µm (180 µinch).
Straightness
Out-of-straightness is defined as the maximum deviation from a straight-edge of specified length. The following values apply:

0.011 | Disclaimer
Recommendations are for guidance only, and the suitability of a material for a specific application can be confirmed only when we know the actual service conditions. Continuous development may necessitate changes in technical data without notice.
This data sheet is only valid for Biquick material. Other material, covering the same international specifications, does not necessarily comply with the mechanical and corrosion properties presented in this datasheet.
