Nitrided Steel Welding Table
Application:Welding&Assemble
Process:CNC Machining
Surface treatment:Normal/Nitrided
Type:3D
Brand:Lemar
Product Description
Our Nitrided Steel Welding Table is a premium industrial work surface engineered for serious fabrication shops. Through advanced nitriding technology, the steel surface is hardened to HV 900–1200 - delivering 5–10 times the wear resistance of ordinary welding tables. The nitrided finish repels weld spatter, resists scratches and dents, and provides built-in rust protection, dramatically reducing maintenance time and extending service life to 10+ years. Combined with precision CNC-machined 100mm fixturing grids and heavy-duty Q355 steel construction, it's the durable, low-maintenance foundation your workshop deserves.

Product Advantages
💎Weld Spatter Wipes Right Off
Forget the chipping hammer and grinder. The nitrided surface creates a non-stick barrier that prevents weld spatter from bonding to the steel. Most spatter beads up and falls off on its own; the rest wipes away with a simple wire brush in seconds. Spend less time cleaning, more time welding.
💎 Extreme Surface Hardness - Scratch & Dent Resistant
At HV 900–1200 surface hardness, your table stands up to everything your shop throws at it: heavy steel parts sliding across the surface, clamp pressure, tool drops, sharp edges. No more dents, no more gouges, no more worn-out hole walls - the table stays flat, smooth, and precise shift after shift, year after year.
💎 Built-In Rust & Corrosion Protection
The nitrided layer combined with post-oxidation black oxide treatment creates a dual-layer corrosion barrier. Humid workshops, oily environments, and even occasional moisture exposure won't cause rust. No more daily oiling routines, no more rust spots creeping across your work surface. Low maintenance, high performance.
💎 Guaranteed Flatness - No Warping from Treatment
Unlike other hardening methods that distort the metal at high temperatures, our plasma nitriding process operates at moderate heat, preserving the table's dimensional accuracy. Every table is precision-measured after nitriding to ensure flatness within 0.1mm per meter - delivering the geometric stability your precision fabrication work demands.
Product Application

High-Volume Production Welding - Less cleanup time = more parts per shift
Precision Fabrication & Jig Work - Consistent flatness and hole accuracy for repeatable results
Automotive & Chassis Manufacturing - Heavy clamping, frequent part sliding, high-wear environment
Heavy Equipment & Agricultural Machinery - Big, heavy, abrasive parts that destroy ordinary tables
Robotic Welding Cells - Long-term precision and durability for automated production lines
Shipbuilding & Offshore Fabrication - Humid, corrosive environments where rust is a constant battle
Job Shops & Contract Fabrication - Impress clients with clean, professional work surfaces
Training Centers & Tech Schools - Withstands heavy student use with minimal maintenance
Nitrided vs. Regular Welding Tables - The Side-by-Side Difference
| Aspect | Standard Untreated Table | Our Nitrided Steel Welding Table |
|---|---|---|
| Surface Hardness | ~HV 150–200 (soft steel) | HV 900–1200 (5–10× harder) |
| Weld Spatter | Sticks firmly, requires grinding | Wipes off easily with a brush |
| Rust Resistance | Rusts easily, needs constant oiling | Dual-layer corrosion protection, virtually rust-proof |
| Wear Resistance | Holes wear out in 1–2 years | Hole walls stay precise for 8–10+ years |
| Flatness Retention | Dents & warps easily | Stays flat under heavy daily use |
| Maintenance | High - oiling, grinding, repairing | Low - just wipe clean |
| Lifespan | 2–3 years typical | 10+ years under daily industrial use |
| Total Cost of Ownership | High - frequent replacements | Low - one-time investment, decades of service |
