Detailed Product Description

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

Frequently Asked Questions

What industries use this D16 2D welding tables?

Construction machinery, railway/automotive manufacturing, new energy (battery trays, storage cabinets), and general metal fabrication.

What is the lead time?

Standard sizes: 7-15 working days. Custom sizes: 15-25 working days.

What is the warranty?

12-month warranty against manufacturing defects.

Do you provide export documents?

Yes, including material test reports, heat treatment certificates, dimensional inspection reports, and CE declarations.

Do you provide technical support?

Yes, our team can provide guidance on table installation, accessory selection, and workpiece positioning via email, WhatsApp, or video call.

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.
