D28 28mm Nitrided Cast Iron 3D Welding Work Table with Clamps
Product Introduction
The D28 28mm Nitrided Cast Iron 3D Welding Work Table with Clamps is a five-sided modular fixture platform constructed from HT300 cast iron with complete gas nitriding finish. Features standard Φ28mm holes with 100×100mm grid pitch, delivering high precision flatness and perpendicularity. Complete with matched D28 clamping kits for flexible workpiece positioning and welding fixture setup. Widely used in heavy metal fabrication and batch welding production.
Materials and Craftsmanship
Base Material: HT300 high-grade gray cast iron (superior to HT250), cast with overall stress relief annealing. Reinforced structure with internal reinforcement provides deformation resistance and shock absorption far exceeding carbon steel platforms. Long-term heavy load flatness remains stable, with blank Brinell hardness of HB180~210.
Surface Treatment: Complete gas nitriding of the 3D welding table
Nitriding Specifications: Layer depth 0.25~0.3mm, surface hardness HV420~630
Advantages: High temperature resistance to welding slag splashing, rust and corrosion resistance, wear and scratch resistance, easy detachment of welding slag, prevention of platform rust and hole blockage. Standard process for high-end welding platforms.
Appearance: Matte black-gray nitriding surface layer, no paint peeling issues.
Processing Technology: Full table and four sides CNC precision milling and drilling, full-size one-time clamping processing ensures hole position, plane, and perpendicularity tolerances.

Core Advantages
- 3D Five-Sided Use: Top surface plus four full holes on facades enable clamping at any point in X/Y/Z 3D space
- Double Durability: Cast iron provides shock absorption and resistance to welding stress; nitriding resists welding slag and rust
- Universal Modularity: Worldwide compatibility with D28 system fixtures and accessories
- Cost Reduction: Replaces traditional marking and custom fixtures, reduces production time by over 60%
FAQ
Is nitriding treatment better than painted surface?
Yes. Nitriding layer resists high temperature welding spatter, rust and scratch effectively. Weld slag falls off easily without peeling, far more durable than ordinary painted carbon steel tables.
Can table legs be adjusted in height? Optional moving casters?
Standard support legs come with adjustable leveling feet. Brake-type moving casters are available as optional accessories for flexible workshop transfer.
What industries is this 3D welding table suitable for?
Widely used in heavy steel fabrication, machinery frames, agricultural parts, vehicle frames, sheet metal and automated equipment fixture welding.
What's your delivery term and lead time?
We support FOB, CFR, CIF and DDP terms. Standard stock items ship in 7-15 working days, customized tables need 15-25 working days production period.
