Technical delivery terms PRÄZI Flachstahl

( Dimensions in mm )

Range of application:
These specifications apply for fine-machinedbars in the followngi ranges of application:

  • from 10 to 500 mm width for flat steel dimensions
  • from 1 to 100 mm thickness for flat steel dimensions
  • 500, 1000 and 1030 mm length for flat steel dimensions
  • from 4 to 150 mm side length for square steel dimensions.
  • It does not apply to:
  • bright flat steel according to DIN EN 10278
  • bright squares according to DIN EN 10278
  • cold-rolled steel strip according to DIN EN 10140

Concept
Precision flat steel and square steel are sharp-edged bars with fine
machined longitudinal surfaces free of decarburisation.

Designation
The following are to be indicated in the designation in the seuqence given below:

  • Name (PRÄZI Flachstahl)
  • Delivery conditions (DIN 59350,mit Bearbeitungsaufmaß)
  • Abbreviation or material number
  • Nominal sizes (flat steel: width, thickness, length; square steel: thickness, length)

Example:

PRÄZI Flachstahl DIN 59350
1.2842 150 x 30 x 100 mm

PRÄZI Flachstahl mit Bearbeitungsaufmaß
1.2436 Vkt. 20,4 x 1030 mm

Dimensions, permissible dimensional deviations and deviations of form
The permissible deviations from the nominal sizes are as follows:

For PRÄZI- flat steel according to DIN 59 350

Thickness grounded / fine-machined Tol.: +0,05 / - 0 mm
Width grounded / fine-machined Tol.: +0,2 / - 0 mm

Length, one fine-machined end face,
one rough-machined end face

Tol.: +5 mm
 Square steel dimensions, thickness Tol.: +0,05 / - 0 mm

 

For PRÄZI- flat steel according to DIN 59 350 with machining allowance:

Thickness grounded / fine-machined Tol.: +0,2 / - 0 mm
Width grounded / fine-machined Tol.: +0,2 / - 0 mm

Length, one fine-machined end face,
one rough-machined end face

Tol.: +5 mm
Square steel dimensions , thicknessTol.: +0,20 / - 0 mm

 

Angular deviation for PRÄZI- flat steel according to DIN 59350
The permissible angular deviation between the side faces and between
the end faces and these faces 0°15´.

For PRÄZI flat steel with machining allowance:

Thickness grounded / fine-machined Tol.: + 0,25 / - 0 mm
Width grounded / fine-machined Tol.: + 0,4 / - 0 mm

Length fine-machined / sawn length 500 mm

Tol.: + 20 mm
Length fine-machined / sawn length 1030 mm Tol.: +/- 20 mm
Square steel dimensions , thickness Tol.: + 0,25 / - 0 mm

 

Angular deviation
The permissible angular deviation between the side faces is 0°15´.

Parallelism
The parallelism lies within the permissible dimensional tolerances. Deviations
therefrom are to be agreed when ordering.

Surface roughness
The figures for the peak-to-valley height relate in the case of

  • precision flat steel to the wide longitudinal sides
  • precision square steel bars to all longitudinal sides

It is for

  • bars without machining allowance     Ra ≤ 2 μm
  • bars with machining allowance           Ra ≤ 6 μm
  • bars with machining over-measure    Ra ≤ 6 μm

Heat treatment condition
The steels are normally delivered in a soft-annealed condition, other
heat treatment conditions are to be agreed when ordering.

Planeness and straightness
The deviation from the planeness and straightness are indicated in
the table below. They are measured on an individual piece along the
longitudinal and short sides with a feeler gauge. The test specimen is
to lie freely on a plane board.

Width (mm) thickness ( mm )
  >1 ≤2,2 >2,2 ≤5,2 >5,2 ≤10,4 >10,4 ≤20,4 >20,4
≤ 100,3 (1,0) 0,8 0,7 0,5 0,3
>100,3 ≤200,3 (1,5) 1,1 0,8 0,6 0,4
>200,3 ≤300,3 (2,0) 1,5 0,9 0,8 0,5
 >300,3 ≤500,3 (2,3)  2,0 1,2 1,0 0,8

For the small thicknesses, changes in planeness are possible.
Figures in brackets are only approximate values.
