Terms and Conditions of Sale
A number of standard coatings are offered for different applications and operating environments. Ultra-low temperature variants, Hardide-LT and Hardide-LA, are available which are suitable for coating grades of steel and alloys sensitive to the 500OC / 932OF process temperature. Hardide-LT and Hardide-LA are produced at the significantly lower temperature of 350OC / 662OF. All Hardide coatings can be applied to external and internal surfaces including complex geometries.

‘the Rockwell (Rc) values are for illustration only as the Rc hardness test method uses high loads which are not suitable for coatings
Customer coatings can be developed for specific requirements. The capability of our in-house technical and engineering teams, and the flexibility of our coatings’ properties allows us to develop coatings for your specific needs.
We can engineer a solution for many complex applications and wear, erosion or corrosion problems that other coating technologies cannot solve e.g: Hardide-A was developed specifically to meet the needs of the aerospace industry and as a direct replacement for hard chrome plating (HCP which faces legislative EU restrictions. Hardide-A matches HCP in thickness (100 microns) and hardness (>800 Hv) and outperforms the material in several key properties including enhanced protection against corrosion, wear and chemically aggressive media. No significant changes are necessary in part dimension or drawings.
We recently developed a coating specifically for a customer who needed high chemical purity and enhanced thermal management properties but not coating hardness. The coating was therefore developed with low hardness, high purity and very low internal stresses to meet this customer’s needs.
