Surface Nitriding Treatment of D16 2D Welding Table
Product Overview
- Durable Precision: Positioning holes show no wear even after long-term use; hole spacing and flatness remain unchanged for years.
- Superior Wear Resistance: Frequent clamping and tooling changes will not cause scratches or roughening of the surface.
- Minimum Maintenance Required: No need for frequent application of rust-preventive oil; resistant to rust even in humid workshops or outdoor storage.
- Double lifespan: Surface Nitriding Treatment of D16 2D Welding Table is more than three times more durable than regular blackened countertops
- Premium Appearance: Uniform matte gray-black surface with superior texture.

Surface Nitriding Treatment Process
Process Principle
In a low-temperature sealed furnace at 500-580°C, ammonia gas (NH₃) or nitrogen gas is introduced to decompose active nitrogen atoms [N], which penetrate into the surface layer of the steel (depth 0.2-0.5mm) and combine with iron/alloy elements to form high hardness nitride layers.
Mainstream Process Types
- Gas Nitriding: Most commonly used, 510-550°C, NH₃ atmosphere, hardness HV600-700, takes 20-60 hours, suitable for mass production.
- Plasma/Ion Nitriding: Vacuum glow discharge, 350-450°C, N₂/H₂ plasma, hardness HV1000-1200, time-saving 30-50%, more environmentally friendly, suitable for high-precision/stainless steel parts.
- Corrosion Resistant Nitriding: Low temperature for short period, forming dense nitride film, salt spray resistance ≥500h, rust prevention is primary focus.
Core Performance (After Nitriding)
- Surface Hardness: HV600-700, 2-3 times higher than untreated steel (HV280-320)
- Wear Resistance Life: Increased by 3-5 times, positioning holes/tabletops less prone to wear and maintain accuracy long-term
- Corrosion Resistance: Dense nitride layer isolates water vapor/acid and alkali, increasing rust prevention ability by 5-10 times
- Dimensional Stability: Low temperature treatment, deformation ≤0.02mm/m, minimal change in flatness and hole spacing accuracy
- Fatigue Strength: Surface compressive stress (200-400MPa) increases fatigue life by 3-5 times

Maintenance and Lifespan
Routine Maintenance
Nitriding countertops do not require frequent brushing of rust proof oil. Daily cleaning of welding slag and iron filings is sufficient. Avoid prolonged scratching by hard objects. Regularly clean debris in positioning holes to prevent iron filings from blocking and affecting pin installation.
Service Life
Under normal operating conditions, the Surface Nitriding Treatment of D16 2D Welding Table service life can reach 8-10 years, which is more than three times longer than ordinary blackened versions (2-3 years), providing higher overall cost-effectiveness.
