Hard Inchromising for Ball Segment Valve Heads

In the (petro)chemical, pharmaceutical, and food industries, high-quality stainless steel alloys and nickel-based materials are frequently utilised. Although the choice of these materials may seem straightforward, they are unfortunately susceptible to corrosion and wear under certain conditions.

When these materials are used in dynamic components, conventional techniques and materials often fall short in aggressive and abrasive environments where both wear resistance and corrosion resistance are crucial. Corrosion-induced wear or wear-induced corrosion leads to rapid degradation of machine parts, causing unscheduled production downtimes and resulting in unnecessary costs and frustration.

If the chosen stainless steel material has sufficient corrosion resistance but wear or cold welding poses a challenge, Hard Inchromising may be the ideal solution. This treatment produces an exceptionally hard and wear-resistant surface while preserving corrosion resistance, with minimal effect on product dimensions. This treatment method is being widely adopted across various industries, including recent applications in the soldering sector.

This treatment method enhances product wear resistance by applying a ceramic chrome carbide (CrxCy) layer. Wherever abrasive or adhesive wear occurs, this unique layer greatly extends the service life of components. The treated surface is extremely hard-wearing, with a dense structure and excellent operational properties. Hard inchromising ensures a longer service life, less downtime, fewer costly production halts, and lower overall expenses.
