Thermal Spray and HFW 512 Coating: Up to 30x Increase in Service Life

At HFW, we don’t just talk about saving our customers time and money—we back it up with proven data. Contact our team to discuss how we can deliver transformative results for your operation. 

From Months to Years: A Proven Success Story

In the 1980s, a customer in the chemical processing industry approached HFW with a major challenge: its rolls were only lasting two months in service. Short lifespans like these can lead to high maintenance costs and expensive downtime within the chemical industry—problems that impact production efficiency and profitability.

HFW quickly improved roll performance to 4–5 months using our standard thermal spray coating processes. But we didn’t stop there.

The Power of the HFW 512 Alloy

The real breakthrough came when we began experimenting with HFW 512, our proprietary nickel-based alloy thermal spray powder that’s been successfully applied across multiple industries. Working in partnership with the customer’s metallurgist, we applied HFW 512 using our HVOF thermal spray process.

The results were significant:

• Roll lifespan increased from months to 5–6 years in service
• Long-term cost savings far exceeded the initial coating investment
• With over 40 years of documented performance data, this is a data-backed solution.

Why This Matters for Chemical Processors

In chemical manufacturing, downtime is more than an inconvenience. It’s an expense that can cost thousands of dollars per hour. By extending roll life with advanced thermal spray coatings, HFW helps customers:

• Reduce roll downtime and maintenance-related shutdowns
• Improve reliability and production efficiency
• Lower total cost of ownership for critical equipment
• For plant managers and purchasing teams, this is actionable data that justifies investment and drives measurable ROI

Real Results Backed by Decades of Data

It’s one thing to say you can improve equipment performance. It’s another to have decades of proof.

The attached graph shows the dramatic reduction in the number of rolls HFW rebuilt for our customer after adopting HFW 512. This is the power of combining metallurgical expertise with advanced thermal spray coating technology.
