VAUTID WEAR PLATESThe three decisive

differences

1. Highly wear resistant means longlifetime

The decisive advantages: VAUTID wear plates can-not be compared with sheets hardfaced with theconventional method.

For their manufacture we employ the VAUTID-Metalarc-Process:

Characteristic Your advantage

1. Minimal dilution with Minimal riskbase material of breakage

2. Selection of alloys Maximumto suit the application reliabilitye.g., VAUTID-00,-43, -45, -50, -200

3. Rapid cooling of the Durable,highly alloyed smelting dependable partsbath

2. Deposited layer is tailored according to the application:Deposits of one or more layers available made with:VAUTID-90, VAUTID-00, VAUTID-00 K, VAUTID-00 T, VAUTID-43, VAUTID-45, VAUTID-50, VAUTID-76,VAUTID-200, VAUTID-300.

3. Easy to install due to simple fixing methods

t welding-on of stud

2. Plates cut to size

from 50 x 50 mm to 4000 x 4000 mm

square boring from 4 x 4 mmcircular boring from 3 mm ltear shape boring from 3 mm lslots from 1 mm

The plates are cut with plasma-, laser- and waterjets.

3. Formed platesSimple cold forming is possible only with VAUTIDwear plates because of their low dilution betweenweld deposit and base material.

The smallest cold-rolled diameter is 70 mm.

4. Ready-to-install constructions

Structure of a VAUTID wear plate[mm], with one layer of hardsur-facing by means of the VAUTID-Metal-Arc-process:

The structure of the hardfacinglayer shows a high content ofprimary chromium carbides al-ready close to the base metal.

A further important characteristicof quality is non-melted powderparticles, which proves that thewelding material is saturated withcomponents of the alloy.

Structure of a one layer flux-cored [mm] wire hardsurfacing:

The dilution with the base materialreduces the Cr and C content.This leads to a lower percentageof primary chromium carbides.These exist only close to the sur-face.
