In metalworking, the cleaning stage is one of the most critical steps to ensure final product quality.
For ferrous metal machining in particular, growing process complexity and higher precision requirements are making cleaning more challenging than ever.
If you work in these environments, you may have faced similar issues:
-
Residual oil and metal chips remain on the surface, leading to inconsistent tempering or coating performance.
-
Rust spots or flash rusting occur after cleaning—sometimes affecting appearance, other times causing full product scrap.
-
Excessive foaming, poor oil-water separation, and short bath life result in low equipment efficiency and unpleasant odors.
These problems don’t just affect quality—they disrupt production schedules and drive up costs.
So, how can we achieve fast, thorough, eco-friendly, and safe cleaning?
KERUN Industrial Fluids Co., Ltd. presents a proven solution: KR-F400H Water-Based Metal Cleaner—engineered specifically for high-performance cleaning of ferrous metals.
Why KR-F400H Stands Out in Industrial Metal Cleaning
01. Why KR-F400H Stands Out in Industrial Metal Cleaning
In ferrous metal processing, stubborn contaminants such as high-viscosity quenching oils, cutting fluids, rust-preventive oils, and mechanical lubricants often adhere firmly to the workpiece surface, making them difficult to remove. As component designs become more intricate, traditional cleaning agents frequently fall short.
KR-F400H is specifically formulated to tackle these common yet challenging contaminants. It delivers exceptional degreasing performance across various applications—including pre-cleaning before heat treatment, inter-process cleaning, and precision cleaning prior to packaging.
Notably, KR-F400H demonstrates superior oil separation and cleaning efficiency against notoriously difficult contaminants such as black quenching oils, ensuring a clean, residue-free surface ready for downstream processes.

02. In-Process Corrosion Protection – Eliminating Flash Rust Concerns
The appearance of rust spots within a short time after cleaning is one of the most frustrating issues on the production floor—especially during tempering or while waiting between process stages.
KR-F400H incorporates a stable corrosion-inhibition system, delivering excellent in-process rust protection. Even in humid or elevated-temperature environments, it ensures reliable short-term protection between stages, maintaining both process continuity and surface appearance quality of the parts.

03. Excellent Oil-Water Separation for Extended Bath Life and Lower Operating Costs
In industrial cleaning operations, as oil contaminants are continuously introduced, uncontrolled emulsification of the cleaning fluid can quickly degrade the bath—causing foul odors, reduced cleaning power, and more frequent fluid changes and maintenance. This not only affects workpiece cleanliness but also disrupts production schedules.
KR-F400H offers outstanding oil-water separation performance, effectively suppressing bath emulsification and maintaining long-term fluid stability. This extends service life, reduces fluid replacement frequency, and lowers operating costs.
Even when exposed to high-viscosity oils, KR-F400H maintains stable separation and consistent cleaning power. Its sodium-free formulation is compatible with a wide range of cleaning systems—including spray, bubbling, ultrasonic, and jet cleaning—providing safe, corrosion-free operation for equipment and ensuring stable, reliable performance.

04. Eco-Friendly and Safe – Cleaning with Confidence
KR-F400H is free from nitrites, phosphates, and other components that can pollute water systems, aligning perfectly with modern green manufacturing principles. Its formulation is both environmentally responsible and safe to use.
The product also offers excellent storage stability—even after long-term storage, it shows no sedimentation, no phase separation, and no loss in cleaning performance. This makes KR-F400H not only reliable in operation but also worry-free to store and manage.
It is an ideal choice for manufacturers committed to long-term environmental stewardship and clean production practices.
