TISCO Receives Patent for Groundbreaking Low-Nickel Stainless Steel Welding Wire
TISCO has been granted a patent (CN120460847A) for an innovative austenitic welding wire that addresses key challenges in joining low-nickel, nitrogen-reinforced stainless steel.
This technology addresses a long-standing industry pain point: achieving high-strength, corrosion-resistant welds on cost-effective stainless steel.
Core Innovation
This patented welding wire utilizes a unique composition that reduces nickel content while maintaining weld integrity:
| Element | Range (wt%) | Function |
| Nickel | 5.0-5.5% | Cost reduction vs standard wires |
| Nitrogen | 0.15-0.25% | Strength compensator |
| Manganese | 8.5-9.5% | Austenite stabilizer |
| Chromium | 17.0-18.5% | Corrosion protection |
Solving Practical Welding Problems
Conventional low-nickel stainless steel welds often suffer from the following issues:
Weak heat-affected zone
Cracking in corrosive environments
Reduced ductility
Target Applications
Chemical processing tanks
Food equipment manufacturing
Structural components in coastal environments
Budget-sensitive construction projects
As a leading stainless steel supplier in Shanghai, Womei Group has established strategic partnerships with over 25 renowned domestic steel mills, including TISCO, ensuring superior product quality.
Walmay Steel believes this advancement is particularly important for manufacturers working with 201/202 series stainless steels, as weld quality in these series has historically been challenging.
