Hardened and high tensile steel

Hardened and high-strength steel are used more and more frequently. This means that the right corrosion protection has to be available for products made from these types of steel.

Sherart can use adapted process temperatures to successfully protect hardened and high-strength types of steel while retaining their properties. The gradual warming and cooling of the products mean that sherardizing does not add internal stresses to the base material.

Sherardizing is a dry galvanizing process and this means no risk of hydrogen embrittlement. Any pretreatment involves shotblasting, which excludes the possibility of any hydrogen embrittlement.

During the sherardizing, diffusion galvanizing at temperatures lower than 420°C, no liquid metal embrittlement is introduced into the steel.
