Introduction: When Standard Tools Fail
Every metalworker or builder has faced this situation at least once: you take a familiar cutting disc, start cutting stainless steel, and the tool quickly dulls, overheats, and produces an uneven cut. The problem isn't with technique or experience – it's the unique properties of stainless steel INOX that require a completely different approach to processing.
Modern industry uses stainless steel everywhere: from kitchen equipment to chemical reactors. But without understanding the specifics of this material and proper selection of abrasive tools, even an experienced craftsman can encounter serious difficulties.
What Makes Stainless Steel Special
Chemical Composition and INOX Structure
Stainless steel (from French "inoxydable" – stainless) contains a minimum of 10.5% chromium, which forms a thin protective film of chromium oxide on the surface. Additional alloying elements determine specific properties:
Main groups of stainless steels:
- Austenitic (304, 316, 321) – contain nickel, non-magnetic, high corrosion resistance
- Ferritic (430, 409) – magnetic, less alloyed, economical
- Martensitic (410, 420) – hardenable, high hardness
- Duplex – combination of austenitic and ferritic structures
Critical Properties for Processing
Low thermal conductivity – 3-4 times worse than carbon steel. Heat concentrates in the cutting zone, causing overheating of both tool and workpiece.
High toughness and plasticity – material "smears" onto abrasive grains, quickly clogging disc pores.
Work hardening – under mechanical loads, the surface layer becomes significantly harder, complicating further processing.
Tendency to stick – metal particles firmly adhere to the abrasive, forming "glazing" on the disc surface.
Why Standard Discs Don't Work for INOX
Rapid Clogging and Loss of Efficiency
Standard abrasive discs based on aluminum oxide or silicon carbide when working with stainless steel:
- Clog with metal particles within 2-3 minutes of active work
- Lose up to 70% of cutting ability due to surface "dulling"
- Require frequent dressing or replacement, increasing work costs
Thermal Problems
Heat concentration in the processing zone leads to:
- Metal structure changes – martensite formation in austenitic steels
- Heat tint appearance – sign of overheating and loss of corrosion resistance
- Microcrack formation – especially critical for critical components
- Thin workpiece warping due to thermal stresses
Surface Quality
Using unsuitable tools results in:
- Rough, non-uniform surface with deep scratches
- Waviness and geometric deviations
- Surface layer work hardening
- Residual stresses reducing fatigue strength

Optimal Operating Modes
Cutting speed: 20-30% lower than for carbon steel
Feed: slow, steady, without jerks or excessive pressure
Cooling: mandatory for thick workpieces, water-soluble coolants
Safety When Working with INOX
- Use protective goggles and respirator (stainless dust is toxic)
- Monitor workpiece temperature
- Regular breaks for tool cooling
- Check disc balance before operation

Frequently Asked Questions (FAQ)
How do NovoAbrasive stainless steel discs differ from standard ones?
Special NovoAbrasive discs contain unique abrasive grains (zirconia-alumina), modified bonding with anti-adhesion properties, and optimized pore structure. This provides 5-7 times longer service life and stable cutting quality when processing stainless steel.
Can one disc be used for different stainless steel grades?
Yes, modern universal NovoAbrasive PROFI series discs are suitable for most common stainless steel grades (304, 316, 430). However, for specific tasks (duplex steel processing, high-alloy materials), consultation with plant specialists is recommended.
What cooling is best when working with INOX?
Water-soluble cooling (emulsion) with 5-8% concentration is most effective. For thin workpieces, periodic air cooling is sufficient. Oil cooling is less effective due to low thermal conductivity of stainless steel.
How to determine when to replace a disc when working with stainless steel?
Main wear signs: sharp increase in cutting time, unusual color sparks, burns on workpiece, increased tool vibration. When working with INOX, disc replacement is needed earlier than wear is visually noticeable.
