Sieve insert 4 mm square perforation made of chromium-free steel ST12
Sieve inserts determine the fineness of a sample
Sieve inserts with trapezoidal perforation and square perforations are offered. Sieve inserts with square perforation are recommended for the grinding of brittle materials and materials of medium fineness with a narrow grain band. Sieve inserts with trapezoidal perforations improve size reduction through extra shearing action.
Sieve inserts made of chromium free steel ST 12 are especially recommended for the sample preparation according to RoHS and WEEE (for the poof of hexavalent chromium) and for the XRF-analysis. For all other applications, sieve inserts made of stainless steel may be used, since these are harder and therefore more resilient against abrasion.
