Malcomizing

In order to extend the life of your blades in abrasive environments, we can offer surface hardened blades sometimes referred to as DuraTuf. The hardened blades are prepared by the Malcomizing process. In this heat treating process the passive oxide surface film of the stainless steel is broken down to permit nitrogen diffusion into the steel, at relatively low temperatures. This increases the Hardness to around 64-68 Rockwell C.

Although resistance to wear is the primary consideration, unlike other processes for hardening stainless steels, Malcomizing improves the fatigue life of the steel under dynamic stress. This reduces the likelihood of cracks forming as a result of the blade flexing during mixing.

Our blade are used for both solvent and water-based coatings. Malcomized stainless steel retains corrosion resistance superior to that of stainless steel subjected to conventional nitriding, and far superior to nitrided low alloys.

The comparatively low temperatures involved in the process tends to minimizes distortion. Our Malcomized blades will show some distortion from the process, but this will not adversely affect operation.
