Our Materials

We offer welding tables crafted from diverse materials: ranging from standard steel to various grades of alloy nitrided steel. These alloy nitrided steels feature exceptionally high base material hardness, which is crucial for the welding table’s superior impact resistance and extended service life.

Additionally, we refine the surface through plasma nitriding. This innovative treatment significantly enhances surface hardness, delivering orders-of-magnitude improvements in surface hardness, wear resistance, and corrosion resistance. The core retains high strength and toughness with minimal deformation, effectively preventing scratches, corrosion, and weld spatter adhesion. This makes them ideal for precision, high-load friction components.

The unique combination of high base hardness and surface treatment results in exceptional surface wear resistance and durability, ensuring reliable operation even under the most demanding conditions.

Why Choose Plasma Nitriding?

464

High Hardness and Wear Resistance

The hardened surface provides exceptional scratch, dent, and abrasion resistance, maintaining flatness even under heavy-duty use and extending service life by 3 to 10 times.

容境，序号1-01

Superior Corrosion Resistance

The dense protective layer provides robust defense against moisture, welding residues, and corrosive environments, ensuring durability and longevity even under demanding conditions.

容境，序号1-012

High Bond Strength with Zero Peeling Risk

The nitrided layer exhibits exceptional stability and resistance to peeling, even under impact loads and high-frequency vibration conditions (e.g., engine camshafts, drive shafts).

Reduced Welding Spatter Adhesion

Plasma nitriding significantly diminishes the adhesion of welding spatter to surfaces. Since welding residues can be effortlessly removed, cleaning becomes easier and maintenance requirements are reduced.
