Material Options & Surface Protection

Engineered for performance, built for longevity
Siegmund tables are available in a range of high quality materials, including standard steel, high grade tool steel and corrosion resistant stainless steel. Each material option can be enhanced with plasma nitriding, allowing users to match their table selection to specific performance and durability requirements.
The exclusive X8.7 and X8.8 tool steels offer significantly higher base hardness compared to conventional options, ensuring superior impact resistance and a longer service life. Combined with advanced plasma nitriding and BAR coating, these surfaces gain enhanced protection against wear, corrosion and weld spatter, ideal for demanding industrial environments.

Plasma Nitration
Proven surface treatment for long-lasting welding tables
Siegmund’s welding tables have been plasma nitrided as standard since 2009. With years of experience and ongoing process optimisation, we have developed a welding table that stands out for its robustness and durability, making it nearly unmatched by other products.
What is plasma nitration?
Plasma nitriding is a vacuum based heat treatment that hardens the surface by diffusing nitrogen into the material at around 500 °C, creating a wear and corrosion resistant layer. The process produces minimal distortion and is environmentally friendly, using only nitrogen, hydrogen and oxygen gases naturally found in air. At Siegmund, the process is powered entirely by electricity, avoiding fossil fuels commonly used elsewhere.

Higher Wear Resistance

Corrosion Protection

Minimised Warping

Reduced Weld Spatter Adhesion

Durable Protection No Re-Treatment
BAR-Coating
Unique to Siegmund is the BAR coating applied after plasma nitriding to welding tables and many tool parts. This Black Anti-Rust (BAR) Coating further smooths the surface and enhances protection against corrosion.
Reinforced rust protection
Additional grading and surface refinement
