Castrol Hysol SL 50 XBB Case Study: How to Quadruple Coolant Lifespan in Machining

The problem: Frequent downtime and rising disposal costs

metal manufacturer was facing a common challenge in machining stainless steel and aluminum: its cooling lubricant lasted just 6 months. This translated into recurring plant downtime, constant fluid replacements, and a direct increase in disposal costs, impacting both productivity and the bottom line.

The solution: On-site trial with Castrol Hysol SL 50 XBB

Castrol proposed an on-site trial with Hysol SL 50 XBB, a high-performance soluble metalworking fluid formulated without boron or biocides, designed specifically for processing stainless steel and aluminum.

Results: Up to 2 years of service life without replacement

The trial results were decisive:

• Fluid lifespan extended to 1–2 years without the need for replacement
• Substantial reduction in plant downtime
• Lower used fluid disposal costs
• Improved cutting performance during machining
• Cleaner machine shops with high acceptance from the operator team

Why Castrol Hysol SL 50 XBB makes a difference

The boron- and biocide-free formulation of Castrol Hysol SL 50 XBB not only meets regulatory compliance and plant safety standards, but also sustains fluid performance over much longer lifecycles, reducing maintenance frequency and costs associated with waste management.

If your plant machines stainless steel or aluminum and suffers from frequent downtime due to coolant degradation, this case study applies directly to your operations.
